74AHC245; 74AHCT245
General description
The 74AHC/AHCT245 is a high-speed Si-gate CMOS device.
The 74AHC/AHCT245 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 (OE) input for easy cascading and a send/receive (DIR) input for direction control.
OE controls the outputs so that the buses are effectively isolated.
