The AG76 switches one of 6 inputs ( 6) to a common output,, as determined by the 4-bit binary address lines A,,, and. The AG77 switches one of eight differential inputs to a common differential output as determined by the 3-bit binary address lines A,, and. An input on both devices is used to enable or disable the device. When disabled, all channels are switched OFF. Low-power consumption and operating supply range of.8 V to. V make the AG76 and AG77 ideal for battery-powered, portable instruments. All channels exhibit break-before-make switching action preventing momentary shorting when switching channels. These devices are also designed to operate from a dual supply of ±2. V. These multiplexers 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. The AG76 and AG77 are available in small 28-lead TSSOP packages. CMOS, +.8 V to +. V/ 2. V, 2.

Electrostatic charges as high as 4 V readily accumulate on the human body and test equipment and can discharge without detection. Although the AG76/AG77 features proprietary ES protection circuitry, permanent damage may occur on devices subjected to high energy electrostatic discharges. Therefore, proper ES precautions are recommended to avoid performance degradation or loss of functionality. WARNING! ES SSITIVE EVICE
