HEF4952BT,118

Analog Switches, Multiplexers, Demultiplexers Overview

The HEF4952BT,118 is a dual 3-channel analog multiplexer/demultiplexer with supplementary switches and common select logic. It operates from VDD supply voltages of 5 V, 10 V, or 15 V, with VEE ranging from -15 V to 0 V relative to VSS. The device features Schmitt-trigger action at control inputs and includes input clamp diodes for interfacing signals exceeding VDD. Static characteristics include an OFF-state leakage current of up to 200 nA per channel at 15 V and a maximum ON resistance of 365 Ω at 10 V. Dynamic propagation delays range from 2 ns to 36 ns depending on the supply voltage.
