General description

The HEF4066B provides four single-pole, single-throw analog switch functions. Each switch has two input/output terminals (nY and nZ) and an active HIGH enable input (nE). When nE is LOW, the analog switch is turned off. The HEF4066B is pin compatible with the HEF4016B but exhibits a much lower ON resistance. In addition the ON resistance is relatively constant over the full input signal range.

Features and benefits

■ Fully static operation

■ 5 V, 10 V, and 15 V parametric ratings

■ Standardized symmetrical output characteristics

■ Inputs and outputs are protected against electrostatic effects

■ Specified from 40 C to +85 C and 40 C to +125 C

■ Complies with JEDEC standard JESD 13-B

Applications

■ Analog multiplexing and demultiplexing

■ Digital multiplexing and demultiplexing

■ Signal gating
