1. General description
The 74LV4051 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).
2. Features and benefits
