Overview
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.
