General description

The 74HC245; 74HCT245 is a high-speed Si-gate CMOS device and is pin compatible

with Low-Power Schottky TTL (LSTTL).

The 74HC245; 74HCT245 is an octal transceiver featuring non-inverting 3-state bus

compatible outputs in both send and receive directions. The 74HC245; 74HCT245

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.

The 74HC245; 74HCT245 is similar to the 74HC640; 74HCT640 but has true

(non-inverting) outputs.
