74HC4052

The 74HC4052 and 74HCT4052 are high-speed Si-gate CMOS devices and are pin compatible with the HEF4052B. They are specified in compliance with JEDEC standard no. 7A.

The 74HC4052 and 74HCT4052 are 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.

V_CC and GND of the 74HC4052 are the supply voltage pins for the digital control inputs (pins S0, S1, and E). The V_CC to GND ranges are 2.0 V to 10.0 V for 74HC4052 and 4.5 V to 5.5 V for 74HCT4052. The analog inputs/outputs (pins nY0 to nY3 and nZ) can swing between VCC as a positive limit and V_EE as a negative limit. V_CC − V_EE may not exceed 10.0 V.

For operation as a digital multiplexer/demultiplexer, V_EE is connected to GND (typically ground).
