1. General description

The 74LV4051-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). It is a low-voltage Si-gate CMOS device that is pin and function

compatible with 74HC4051 and 74HCT4051. 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.

VCC and GND are the supply voltage pins for the digital control inputs (S0 to S2, and E). The VCC

to GND ranges are 1.0 V to 6.0 V. The analog inputs/outputs (Y0 to Y7, and Z) can swing between

VCC as a positive limit and VEE as a negative limit. VCC - VEE may not exceed 6.0 V. For operation

as a digital multiplexer/demultiplexer, VEE 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.
