1. General description
74AHC1G66-Q100 and 74AHCT1G66-Q100 are high-speed Si-gate CMOS devices.
They are single-pole single-throw analog switches. The switch has two input/output pins
(Y and Z) and an active HIGH enab le input pin (E). When pin E is LOW, the analog switch
is turned off.
This product has been qualified to the Automotive Electronics Council (AEC) standard
Q100 (Grade 1) and is suitable for use in automotive applications.
