74HC4852-Q100; 74HCT4852-Q100

Dual 4-channel analog multiplexer/demultiplexer with

injection-current effect control

Rev. 1 — 12 July 2012

Product data sheet

1. General description

The 74HC4852-Q100; 74HCT4852-Q100 are high-speed Si-gate CMOS devices and are

specified in compliance with JEDEC standard no. 7A.

The 74HC4852-Q100; 74HCT4852-Q100 are dual 4-channel analog

multiplexers/demultiplexers with common select inputs (S0 and S1). Both multiplexers

have a common active LOW enable input (E), 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 E LOW, two of the eight switches are selected (low impedance ON-state) by S0 and

S1. With E HIGH, all switches are in the high-impedance OFF-state, independent of S0

and S1.

The injection-current effect control allows signals at disabled analog input channels to

exceed the supply voltage without affecting the signal of the enabled analog channel. This

eliminates the need for external diode/resistor networks typically used to keep the analog

channel signals within the supply-voltage range.

This product has been qualified to the Automotive Electronics Council (AEC) standard

Q100 (Grade 1) and is suitable for use in automotive applications.
