74HC245 datasheet


The 74HC245, 74HCT245 is a high-speed Si-gate CMOS device and is pin compatible with Low-Power Schottky TTL (LSTTL).

The device is an octal transceiver featuring non-inverting 3-state bus compatible outputs in both send and receive directions. The features an output enable input (OE) for easy cascading and a send/receive input (DIR) for direction control. OE controls the outputs so that the buses are effectively isolated.
