74HC240; 74HCT240

Octal buffer/line driver; 3-state; inverting

Rev. 03 — 2 August 2007

Product data sheet

1. General description

The 74HC240; 74HCT240 is a high-speed Si-gate CMOS device and is pin compatible

with Low-Power Schottky TTL (LSTTL).

The 74HC240; 74HCT240 is a dual octal inverting buffer/line driver with 3-state outputs.

The 3-state outputs are controlled by the output enable inputs 1OE and 2OE. A HIGH on

nOE causes the outputs to assume a high impedance OFF-state.

The 74HC240; 74HCT240 is similar to the 74HC244; 74HCT244 but has inverting

outputs.

2. Features

Inverting 3-state outputs

Multiple package options

Complies with JEDEC standard no. 7 A

ESD protection:

HBM JESD22-A114-D exceeds 2000 V

MM JESD22-A115-A exceeds 200 V

Speciﬁed from
