HEF4051B datasheet

Description :

The HEF4051B is an 8-channel analog multiplexer/demultiplexer with three address inputs (S1 to S3), an active LOW enable input (E), eight independent inputs/outputs (Y0 to Y7) and a common input/output (Z).

The device contains eight bidirectional analog switches, each with one side connected to anindependent input/output (Y0 to Y7) and the other side connected to a common input/output (Z). With ELOW, one of the eight switches is selected (low-impedance ON-state) by S1 to S3. With EHIGH, all switches are in the high-impedance OFF-state, independent of S1 to S3. If break before make is needed, then it is necessary to use the enable input.

Features : 

1. Fully static operation

2. 5 V, 10 V, and 15 V parametric ratings

3. Standardized symmetrical output characteristics

4. Complies with JEDEC standard JESD 13-B



1. Analog multiplexing and demultiplexing

2. Digital multiplexing and demultiplexing


3. Signal gating
