74HC245D GENERAL DEs criptIONS

The 74HC/HCT245 are high-speed Si-gate CMOS devices

and are pin compatible with low power Schottky TTL

(LSTTL). They are specified in compliance with JEDEC

standard no. 7A.

The 74HC/HCT245 are octal transceivers featuring

non-inverting 3-state bus compatible outputs in both send

and receive directions. The “245” features an output

enable (OE) input for easy cascading and a send/receive

(DIR) for direction control. OE controls the outputs so that

the buses are effectively isolated. The “245” is similar to

the “640” but has true (non-inverting) outputs
