74AHC1G66; 74AHCT1G66 Single-pole single-throw analog switch Rev. 04 — 18 December 2008 Product data sheet 1. General description 74AHC1G66 and 74AHCT1G66 are high-speed Si-gate CMOS devices. They are single-pole single-throw analog switches. The switch has two input/output pins (YandZ) and an active HIGH enable input pin (E). When pinE is LOW, the analog switch is turned off. 2.
