HEF4053 (DS01/DS02)
Triple 2-channel Analog
Multiplexer/Demultiplexer
1. Description
The HEF4053 is a triple 2-channel analog
multiplexer/demultiplexer with a common enable
input (E). Each multiplexer/demultiplexer has two
independent inputs/outputs (Y
common input/output (Z)
Each also contains two-bidirectional analog
