Figure 1. 8-Lead LFCSP 1137-1 SWITCHES SHOWN FOR A LOGIC PUT. Figure 2. 8-Lead MSOP 1137-11 GENERAL ESCRIPTION The is a monolithic industrial, complementary metal oxide semiconductor (CMOS) analog switch containing a latchup immune single-pole/double-throw (SPT) switch. Each switch conducts equally well in both directions when on, and each switch has an input signal range that extends to the power supplies. In the off condition, signal levels up to the supplies are blocked. The exhibits break-before-make switching action for use in multiplexer applications. The ultralow on resistance and on-resistance flatness of these switches make them ideal solutions for data acquisition and gain switching applications where low distortion is critical. The latch-up immune construction and high ES rating make these switches more robust in harsh environments. PROUCT HIGHLIGHTS 1. Trench isolation guards against latch-up. A dielectric trench separates the P channel and N channel transistors, thereby preventing latch-up even under severe overvoltage conditions. 2. Low RON of 13.5 Ω. 3. ual-supply operation. For applications where the analog signal is bipolar, the can be operated from dual supplies up to ±22 V. 4. Single-supply operation. For applications where the analog signal is unipolar, the can be operated from a single-rail power supply up to 4 V. 5. 3 V logic compatible digital inputs: VH = 2. V, VL =.8 V. 6. No VL logic power supply required. 7. Available in 8-lead MSOP and 8-lead, 2 mm 3 mm LFCSP packages. Rev.

ata Sheet TERMOLOGY I I represents the positive supply current. ISS ISS represents the negative supply current. V, VS V and VS represent the analog voltage on Terminal and Terminal S, respectively. RON RON is the ohmic resistance between Terminal and Terminal S. ΔRON ΔRON represents the difference between the RON of any two channels. RFLAT (ON) The difference between the maximum and minimum value of on resistance as measured over the specified analog signal range is represented by RFLAT (ON). IS (Off) IS (Off) is the source leakage current with the switch off. I (Off) I (Off) is the drain leakage current with the switch off. I (On), IS (On) I (On) and IS (On) represent the channel leakage currents with the switch on. VL VL is the maximum input voltage for Logic. VH VH is the minimum input voltage for Logic 1. IL, IH IL and IH represent the low and high input currents of the digital inputs. C (Off) C (Off) represents the off switch drain capacitance, which is measured with reference to ground. CS (Off) CS (Off) represents the off switch source capacitance, which is measured with reference to ground. C (On), CS (On) C (On) and CS (On) represent on switch capacitances, which are measured with reference to ground. C C represents digital input capacitance. ton (EN) ton represents the delay time between the 5% and 9% points of the digital input and switch on condition. See Figure 33. toff (EN) toff represents the delay time between the 5% and 9% points of the digital input and switch off condition. See Figure 33. ttransition ttransition represents the delay time between the 5% and 9% points of the digital inputs and the switch on condition when switching from one address state to another. t t represents the off time measured between the 8% point of both switches when switching from one address state to another. Off Isolation Off isolation is a measure of unwanted signal coupling through an off channel. Charge Injection Charge injection is a measure of the glitch impulse transferred from the digital input to the analog output during switching. Crosstalk Crosstalk is a measure of unwanted signal that is coupled through from one channel to another as a result of parasitic capacitance. Bandwidth Bandwidth is the frequency at which the output is attenuated by 3 db, from its dc level. Total Harmonic istortion + Noise (TH + N) TH + N is the ratio of the harmonic amplitude plus noise of the signal to the fundamental. AC Power Supply Rejection Ratio (ACPSRR) ACPSRR measures the ability of a device to avoid coupling noise and spurious signals that appear on the supply voltage pin to the output of the switch. The dc voltage on the device is modulated by a sine wave of.62 V p-p. The ratio of the amplitude of signal on the output to the amplitude of the modulation is the ACPSRR. See Figure 23. Rev.

ata Sheet APPLICATIONS FORMATION The AG54xx family of switches and multiplexers provide a robust solution for instrumentation, industrial, aerospace, and other harsh environments that are prone to latch-up, which is an undesirable high current state that can lead to device failure and persists until the power supply is turned off. The high voltage switch allows single-supply operation from 9 V to 4 V and dual-supply operation from ±9 V to ±22 V. The (as well as other select devices within this family) achieves an 8 kv human body model ES rating, which provides a robust solution, eliminating the need for separate protection circuitry designs in some applications. TRENCH ISOLATION In the, an insulating oxide layer (trench) is placed between the NMOS and the PMOS transistors of each CMOS switch. Parasitic junctions, which occur between the transistors in junction-isolated switches, are eliminated, and the result is a completely latch-up immune switch. In junction isolation, the N and P wells of the PMOS and NMOS transistors form a diode that is reverse-biased under normal operation. However, during overvoltage conditions, this diode can become forward-biased. The two transistors form a silicon-controlled rectifier (SCR) type circuit, causing a significant amplification of the current that, in turn, leads to latch-up. With trench isolation, this diode is removed, and the result is a latch-up immune switch. TRENCH NMOS PMOS P-WELL N-WELL BURIE OXIE LAYER HANLE WAFER Figure 36. Trench Isolation 1137-3 Rev.
