Description
The Nxp 74HC4052N 74HC4052 is a high-speed Si-gate CMOS device that is pin compatible with the HEF4052B. It is a dual 4-channel analog multiplexer/demultiplexer with common select logic. The device is specified in compliance with JEDEC standard no. 7A and has four independent inputs/outputs and a common input/output. It also has digital select inputs and an active LOW enable input. The supply voltage ranges from 2.0 V to 10.0 V for the 74HC4052 and 4.5 V to 5.5 V for the 74HCT4052. The analog inputs/outputs can swing between VCC and VEE, with VCC - VEE not exceeding 10.0 V. For digital operation, VEE is connected to GND.
The 74HC4052 is a high-speed Si-gate CMOS device and is pin compatible with the HEF4052B. The device is specified in compliance with JEDEC standard no. 7A.
The 74HC4052 is a dual 4-channel analog multiplexer/demultiplexer 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 are 2.0 V to 10.0 V for the 74HC4052 and 4.5 V to 5.5 V for the 74HCT4052. The analog inputs/outputs (pins nY0 to nY3 and nZ) can swing between VCC as a positive limit and VEE as a negative limit. VCC - VEE may not exceed 10.0 V.
For operation as a digital multiplexer/demultiplexer, VEE is connected to GND (typically ground).
