74AHCT245D

Octal bus transceiver; 3-state

The 74AHC245; 74AHCT245 is a high-speed Si-gate CMOS device.

The 74AHC245; 74AHCT245 is an octal transceiver featuring non-inverting 3-state bus compatible outputs in both send and receive directions.

The 74AHC245; 74AHCT245 features an output enable input (OE), for easy cascading, and a send and receive direction control input (DIR).

OE controls the outputs so that the buses are effectively isolated.
