74AHCT245A Octal bus transceiver; 3-state Rev.
2 — 26 October 2016 Product data sheet 1.
General description The 74AHCT245A 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.
The 74AHCT245A is designed to operate over a VCC range from 4.
5 V to 5.
5 V.
The inputs are TTL compatible, which allows the device to be used to translate from 3.
3 V to 5 V.
Schmitt-trigger action at all inputs makes the circuit tolerant of slower input rise and fall times.
This device is fully specified for partial Power-down applications using IOFF.
