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. WithE LOW, one of the eight switches is selected (low impedance ON-state) by S0 to S2. WithE HIGH, all switches are

in the high-impedance OFF-state, independent of S0 to S2.

Features

Optimized for low-voltage applications: 1.0 V to 6.0 V

Accepts TTL input levels between VCC= 2.7 V and VCC= 3.6 V

Low ON resistance:

  145Ω(typical) at VCC−VEE= 2.0 V

  80Ω(typical) at VCC−VEE= 3.0 V

  60Ω(typical) at VCC−VEE= 4.5 V

Logic level translation:

  To enable 3 V logic to communicate with±3 V analog signals

Typical ‘break before make’ built in

ESD protection:

  HBM JESD22-A114E exceeds 2000 V

  MM JESD22-A115-A exceeds 200 V
