74AHC244; 74AHCT244

Octal buffer/line driver; 3-state

Rev. 6 — 2 July 2020

Product data sheet

1. General description

The 74AHC244; 74AHCT244 is an 8-bit buffer/line driver with 3-state outputs. The device can be

used as two 4-bit buffers or one 8-bit buffer. The device features two output enables (1OE and

2OE), each controlling four of the 3-state outputs. A HIGH on nOE causes the outputs to assume

a high-impedance OFF-state. Inputs are overvoltage tolerant. This feature allows the use of these

devices as translators in mixed voltage environments.

2. Features and benefits

•

Wide supply voltage range from 2.0 V to 5.5 V

•

Balanced propagation delays

All inputs have Schmitt-trigger action

Overvoltage tolerant inputs to 5.5 V

High noise immunity

CMOS low power dissipation

Input levels:

•

For 74AHC244: CMOS level

For 74AHCT244: TTL level

•

ESD protection:

•

HBM JESD22-A114F exceeds 2000 V

MM JESD22-A115-A exceeds 200 V

CDM JESD22-C101E exceeds 1000 V

•

Latch-up performance exceeds 100 mA per JESD 78 Class II Level A
