74HC4852; 74HCT4852
Dual 4-channel analog multiplexer/demultiplexer with
injection-current effect control
Rev. 03 — 2 September 2008
Product data sheet
1. General description
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 (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.
