1. General description

The HEF4066B is a quad single pole, single throw analog switch. Each switch features two

input/output terminals (nY and nZ) and an active HIGH enable input (nE). When nE is LOW, the

analog switch is turned off. Inputs include clamp diodes. This enables the use of current limiting

resistors to interface inputs to voltages in excess of VDD.

2. Features and benefits

• Wide supply voltage range from 3.0 V to 15.0 V

• CMOS low power dissipation

• High noise immunity

• Fully static operation

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

• Standardized symmetrical output characteristics

• Inputs and outputs are protected against electrostatic effects

• Complies with JEDEC standard JESD 13-B

• ESD protection :

• HBM JESD22-A114F exceeds 2000 V

• MM JESD22-A115-B exceeds 200 V

• Specified from -40 °C to +85 °C and -40 °C to +125 °C

3. Applications

• Analog multiplexing and demultiplexing

• Digital multiplexing and demultiplexing

• Signal gating
