Dual 4-channel analog multiplexer/demultiplexer with
injection-current effect control

Product data sheet
1. General description

2. Features
The 74HC4852 is a high-speed Si-gate CMOS device and is specified in compliance with
JEDEC standard no. 7A.
The 74HC4852 is a dual 4-channel analog multiplexer or demultiplexer with common
select inputs (S0 and S1). Both multiplexers have a common active LOW enable input (E),
four independent inputs/outputs (pins nY0 to nY3) and a common input/output (pin nZ).
The device features 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.
I Injection-current cross coupling < 1 mV/mA
I Wide supply voltage range from 2.0 V to 6.0 V
I ESD protection:
N HBM JESD22-A114E Class 2 exceeds 2000 V
N MM JESD22-A115-A exceeds 200 V
N CDM JESD22-C101C exceeds 1000 V
I Latch-up performance exceeds 100 mA per JESD 78 Class II
I Low ON-state resistance:
N 400 Ω (typical) at VCC = 2.0 V
N 215 Ω (typical) at VCC = 3.0 V
N 120 Ω (typical) at VCC = 3.3 V
N 76 Ω (typical) at VCC = 4.5 V
N 59 Ω (typical) at VCC = 6.0 V
