A 4- The AG78/AG79 are low voltage, CMOS analog multiplexers comprising eight single channels and four differential channels, respectively. The AG78 switches one of eight inputs (S to S8) to a common output,, as determined by the 3-bit binary address lines A, A, and A2. The AG79 switches one of four differential inputs to a common differential output as determined by the 2-bit binary address lines A and A. An EN input on both devices is used to enable or disable the device. When disabled, all channels are switched off. SB S4B OF 4 ECOER A A EN Figure 2. B 4-2 Low power consumption and an operating supply range of.8 V to 5.5 V make the AG78/AG79 ideal for batterypowered, portable instruments. All channels exhibit breakbefore-make switching action preventing momentary shorting when switching channels. These switches are designed on an enhanced submicron process that provides low power dissipation yet gives high switching speed, very low on resistance, and leakage currents. On resistance is in the region of a few ohms and is closely matched between switches and very flat over the full signal range. These parts can operate equally well as either multiplexers or demultiplexers and have an input signal range that extends to the supplies. PROUCT HIGHLIGHTS. Single-/dual-supply operation. The AG78/AG79 are fully specified and guaranteed with 3 V and 5 V single-supply and ±2.5 V dual-supply rails. 2. Low RON (3 Ω typical). 3. Low power consumption (<. μw). 4. Guaranteed break-before-make switching action. 5. Small 6-lead TSSOP package. The AG78/AG79 are available in a 6-lead TSSOP. Rev.

APPLICATIONS INFORMATION POWER SUPPLY SEQUENCING When using CMOS devices, take care to ensure correct power supply sequencing. Incorrect power supply sequencing can result in the device being subjected to stresses beyond the maximum ratings listed in Figure 4. Always apply digital and analog inputs after power supplies and ground. For single-supply operation, tie VSS to GN as close to the device as possible. Rev. C Page 9 of 2
