Product specification

74HC4052; 74HCT4052

FEATURES

• Wide analog input voltage range from −5 V to +5 V

• Low ON-resistance:

– 80 Ω (typical) at VCC − VEE = 4.5 V

– 70 Ω (typical) at VCC − VEE = 6.0 V

– 60 Ω (typical) at VCC − VEE = 9.0 V

• Logic level translation: to enable 5 V logic to

communicate with ±5 V analog signals

• Typical “break before make” built in

• Complies with JEDEC standard no. 7A

• ESD protection:

– HBM EIA/JESD22-A114-B exceeds 2000 V

– MM EIA/JESD22-A115-A exceeds 200 V.

• Specified from −40 °C to +85 °C and −40 °C to +125 °C.

APPLICATIONS

• Analog multiplexing and demultiplexing

• Digital multiplexing and demultiplexing

• Signal gating.

DESCRIPTION

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.

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 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 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).
