Data Sheet FEATURES Bandwidth: >4 MHz Low insertion loss and on resistance: 2.2 Ω typical On resistance flatness:.3 Ω typical Single 3 V/5 V supply operation Very low distortion: <.3% Low quiescent supply current: 1 na typical Fast switching times ton = 6 ns toff = 3 ns TTL-/CMOS-compatible Pb-free packages 16-lead QSSOP 16-lead 3 mm 3 mm body LFCSP GERAL DESCRIPTION The is a monolithic CMOS device comprising four 2:1 multiplexer/demultiplexers with high impedance outputs. The CMOS process provides low power dissipation yet offers high switching speed and low on resistance. The on resistance variation is typically less than.5 Ω over the input signal range. The bandwidth of the is typically 4 MHz and this, coupled with low distortion (typically.3%), makes the part suitable for switching of high speed data signals. The on resistance profile is very flat over the full analog input range ensuring excellent linearity and low distortion. CMOS construction ensures ultralow power dissipation. The operates from a single 3.3 V/5 V supply and is TTL logic-compatible. The control logic for each switch is shown in the truth table (see Table 5). Low Voltage, 4 MHz, Quad 2:1 Mux with 3 ns Switching Time FUNCTIONAL BLOCK DIAGRAM S1A S1B S2A S2B S3A S3B S4A S4B 1 OF 2 DECODER Figure 1. These switches conduct equally well in both directions when on. In the off condition, signal levels up to the supplies are blocked. The switches exhibit break-before-make switching action. PRODUCT HIGHLIGHTS 1. Wide bandwidth data rates of >4 MHz. 2. Ultralow power dissipation. 3. Low leakage over temperature. 4. Break-before-make switching prevents channel shorting when the switches are configured as a multiplexer. 5. Crosstalk is typically 7 db @ 1 MHz. 6. Off isolation is typically 65 db @ 1 MHz. 7. Available in compact 3 mm 3 mm LFCSP. D1 D2 D3 D4 2373-1 Rev. C Document Feedback Information furnished by Analog Devices is believed to be accurate and reliable.
