Technical Summary: HCC/HCF4066B Quad Bilateral Switch

Overview

The HCC4066B and HCF4066B are monolithic integrated circuits belonging to the "B" series of CMOS devices. These components are quad bilateral switches designed for analog or digital signal switching applications. The HCC4066B is specified for extended temperature ranges, while the HCF4066B is intended for intermediate temperature ranges. Both variants are housed in 14-lead packages, making them suitable for a wide range of industrial and consumer applications.

These devices feature low ON resistance and high OFF impedance, making them ideal for signal routing, multiplexing, and modulation/demodulation circuits. The 4066B series is an improved version of earlier designs, offering better performance and reliability.

Features

• Quad bilateral switch: Four independent switches in a single package.
• Low ON resistance: Typically 80 ohms at V_DD = 10V.
• High OFF impedance: Minimal signal leakage when switches are open.
• Wide supply voltage range: 3V to 15V operation.
• Low power consumption: Typical standby current of 1nA at 25°C.
• High noise immunity: CMOS technology provides excellent noise rejection.
• Matched switch characteristics: Consistent performance across all four switches.
• Break-before-make switching: Prevents signal shorting during transitions.
• Temperature ranges: HCC (-40°C to +125°C), HCF (-40°C to +85°C).
