74HC245; 74HCT245

Octal bus tranceiver; 3-state

Rev. 03 — 31 January 2005

Product data sheet

1. 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.

2. Features

Octal bidirectional bus interface

Non-inverting 3-state outputs

Multiple package options

Complies with JEDEC standard no. 7A

ESD protection:

HBM EIA/JESD22-A114-B exceeds 2000 V

MM EIA/JESD22-A115-A exceeds 200 V

Speciﬁed from
