Description

Product Overview

The CD74HC4066M96 is a quad bilateral analog switch from Texas Instruments (formerly Harris/RCA CD4000 series), packaged in a 14-pin SOIC (M96) package. It contains four independent single-pole single-throw (SPST) analog switches with low on-state resistance and wide analog signal range. The HC version operates from 2V to 10V and supports both analog and digital signal switching.

Key Specifications

Features

  • Four independent SPST bilateral analog switches
  • Low on-state resistance (50Ω typical at 6V)
  • Wide analog signal range from 0V to VCC
  • High bandwidth of 50MHz for video and audio signals
  • Bilateral signal flow — switch handles signals in either direction
  • Extended temperature range: -55°C to +125°C

Applications

  • Analog signal routing and multiplexing
  • Audio and video signal switching
  • Sample-and-hold circuits
  • Programmable gain amplifier switching
  • Battery-operated equipment signal routing

The CD74HC4066 is a quad bilateral analog switch from Texas Instruments, descended from the classic CD4066 design but implemented in high-speed CMOS (HC) technology. It contains four independent SPST switches, each controlled by a separate digital input. The bilateral design allows analog signals to pass in either direction, and the wide signal range (0V to VCC) supports both analog and digital switching applications. With 50Ω on-state resistance and 50MHz bandwidth, the HC version offers significantly improved AC performance over the original CD4066 while maintaining pin compatibility. The extended -55°C to +125°C temperature range suits demanding industrial and military applications.

Each of the four switches in the CD74HC4066 consists of a transmission gate built from a parallel pair of N-channel and P-channel MOSFETs. When the control input (A, B, C, or D) is high, both MOSFETs are turned on, creating a low-resistance bidirectional path between the signal pins. The parallel N/P structure ensures that the on-state resistance remains relatively constant across the full analog signal range from 0V to VCC. When the control input is low, both MOSFETs are off, creating a high-impedance state that blocks signal transmission. The bilateral nature of the MOSFET transmission gate allows signals to flow in either direction through the switch, making it ideal for analog signal routing.
