Overview
74AHC245; 74AHCT245 Octal bus transceiver; 3-state Rev.
6 — 3 July 2020 Product data sheet 1.
General description The 74AHC245; 74AHCT245 is an 8-bit transceiver with 3-state outputs.
The device features an output enable (OE) and send/receive (DIR) for direction control.
A HIGH on OE 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.
