DESCRIPTION
The 74AHC1G/AHCT1G07 is a high-speed Si-gate CMOS
device.
The 74AHC1G/AHCT1G07 provides the non-inverting
buffer.
The output of the 74AHC1G/AHCT1G07 devices is
open-drain and can be connected to other open-drain
outputs to implement active-LOW wired-OR or
active-HIGH wired-AND functions. For digital operation
this device must have a pull-up resistor to establish a logic
HIGH-level.
