Overview
The SN74AHC4066PW is a quadruple bilateral analog switch manufactured by Texas Instruments. It operates within a supply voltage range of 2 V to 5.5 V and features four independent channels configured as single-pole single-throw (SPST) switches. The device utilizes AHC logic series technology, providing a maximum on-resistance of 75 Ohms. It supports switching currents up to 50 mA and exhibits typical turn-on and turn-off times of 12 ns. Designed for surface-mount applications, it is housed in a TSSOP-14 package and functions reliably across an operating temperature range from -40°C to +85°C.
