1. General description
The 74HC4051-Q100; 74HCT4051-Q100 is a high-speed Si-gate CMOS device and is pin
compatible with Low-power Schottky TTL (LSTTL). The device is specified in compliance
with JEDEC standard no. 7A.
The 74HC4051-Q100; 74HCT4051-Q100 is an 8-channel analog
multiplexer/demultiplexer with three digital select inputs (S0 to S2), an active-LOW enable
input (E
), eight independent inputs/outputs (Y0 to Y7) and a common input/output (Z).
With E
LOW, one of the eight switches is selected (low impedance ON-state) by S0 to S2.
With E
HIGH, all switches are in the high-impedance OFF-state, independent of S0 to S2.
V
CC
and GND are the supply voltage pins for the digital control inputs (S0 to S2, and E).
The V
CC
to GND ranges are 2.0 V to 10.0 V for 74HC4051-Q100 and 4.5 V to 5.5 V for
74HCT4051-Q100. The analog inputs/outputs (Y0 to Y7, and Z) can swing between V
CC
as a positive limit and V
EE
as a negative limit. V
CC
V
EE
may not exceed 10.0 V. For
operation as a digital multiplexer/demultiplexer, V
EE
is connected to GND (typically
ground).
This product has been qualified to the Automotive Electronics Council (AEC) standard
Q100 (Grade 1) and is suitable for use in automotive applications.
