Product data sheet
1. General description
The HEF4952B is a dual 3-channel analog multiplexer/demultiplexer with supplementary
switches and common select logic. Each switch features three independent inputs/outputs
(pins nY0, nY1 and nY2) an input/output nY3 that can be connected to nY2 or V_SS and an
input/output (nZ) common to nY0, nY1 and nY2. Three digital select inputs (S1, S2 and
S3) are common to both switches. Inputs include clamp diodes, this enables the use of
current limiting resistors to interface inputs in excess of V_DD.
V_SS and V_DD are the digital control supply pins.
The HEF4952B is suitable for use over the full industrial (−40 °C to +85 °C) temperature
range.
