CD74HCT4066E

Analog Switches, Multiplexers, Demultiplexers Overview

The CD74HCT4066E is a quad single-pole single-throw (SPST) analog switch manufactured by Harris Corporation. It utilizes high-speed CMOS logic technology and features four independent bilateral switches, each with an active HIGH enable input. The device operates on a single supply voltage ranging from 2.0 V to 6.0 V. Key electrical parameters include a maximum on-resistance of 80 Ohms, a typical bandwidth of 200 MHz, and a maximum power supply current of 2 uA. It supports a wide operating temperature range from -55°C to +125°C and is housed in a 14-pin DIP package.
