The 74HC4852; 74HCT4852 are high-speed Si-gate CMOS devices and are specified in compliance with JEDEC standard no. 7A. The 74HC4852; 74HCT4852 are dual 4-channel analog multiplexers/demultiplexers with common select inputs (S0 and S1). Both multiplexers have a common active LOW enable input, four independent inputs/outputs (nY0 to nY3) and two common inputs/outputs (1Z, 2Z). The devices feature injection-current effect control, which has excellent value in automotive applications where voltages in excess of the supply voltage are common. With enable input LOW, two of the eight switches are selected (low impedance ON-state) by S0 and S1. With enable input HIGH, all switches are in the high-impedance OFF-state, independent of S0 and S1.
