HEF4066B
Quad single-pole single-throw analog switch
Rev. 9 19 April 2016 Product data sheet
1. 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.
2. 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
3. Applications
Analog multiplexing and demultiplexing
Digital multiplexing and demultiplexing
Signal gating
