Preliminary Datasheet Dual 4-channel Analog Multiplexer/Demultiplexer AZ4052 General Description The AZ4052 is high-speed si-gate CMOS device. The AZ4052 is dual 4-channel analog multiplexers or demultiplexers with common select logic. Each multiplexer has four independent inputs/outputs (pins nY0 to nY3) and a common input/output (pin nZ). The common channel select logics include two digital select inputs (pins S0 and S1) and an active LOW ___ ___ enable input (pin E). When pin E=LOW, one of the four switches is selected (Low-impedance On-state) ___ with pins S0 and S1. When pin E =HIGH, all switches are in the high-impedance Off-state, independent of pins S0 and S1. VCC and GND are the supply voltage pins for the digital control inputs (pins ___ S0, S1 and E). The VCC to GND ranges ar [ ... ]
