74AHC244; 74AHCT244

Octal buffer/line driver; 3-state

Rev. 05 — 20 December 2007

Product data sheet

1. General description

The 74AHC244; 74AHCT244 is a high-speed Si-gate CMOS device.

The 74AHC244; 74AHCT244 has octal non-inverting buffer/line drivers with 3-state

outputs. The 3-state outputs are controlled by the output enable inputs (nOE). A HIGH on

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

2. Features

Balanced propagation delays

All inputs have a Schmitt-trigger action

Inputs accepts voltages higher than V

For 74AHC244 only: operates with CMOS input levels

For 74AHCT244 only: operates with TTL input levels

ESD protection:

HBM JESD22-A114E exceeds 2000 V

MM JESD22-A115-A exceeds 200 V

CDM JESD22-C101C exceeds 1000 V
