Overview
74HC245; 74HCT245 Octal bus transceiver; 3-state Rev.
6 — 6 September 2021 Product data sheet 1.
General description The 74HC245; 74HCT245 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 include clamp diodes.
This enables the use of current limiting resistors to interface inputs to voltages in excess of VCC.
