CD74HCT4066E TI Analog Switch | 14-PDIP | Quad SPST, 5V Logic

Product Overview

The CD74HCT4066E from Texas Instruments is a high-speed CMOS quad bilateral switch designed for analog or digital signal switching. It features four independent SPST switches with low ON resistance (typically 70Ω at 5V) and wide operating voltage range (2V to 10V). The device is pin-compatible with the CD4066B but offers higher speed due to HCT technology. Housed in a 14-pin PDIP package, it is ideal for multiplexing, signal gating, and sample-and-hold circuits.
