1.7 Analog switch circuit HEF4053BP
1.7.1
Description
The HEF4053 is a triple 2-channel analog multiplexer/demultiplexer with a common enable input (
Each multiplexer/demultiplexer has two independent inputs/outputs (Y
input/output (Z), and select inputs (Sn). Each also contains two-bidirectional analog switches, each
with one side connected to an independent input/output (Y
common input/output(Z). selected (low impedance ON-state) by Sn. With
