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.
