Product data sheet
1. General description
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.
