TEXAS INSTRUMENTS SN54AHCT245 SN74AHCT245 handbook
The document describes the SN54AHCT245 and SN74AHCT245 octal bus transceivers, designed for asynchronous two-way communication between data buses. These devices allow data transmission from the A bus to the B bus or vice versa, depending on the logic level at the direction-control (DIR) input. An output-enable (OE) input can be used to disable the device to isolate the buses.

Questions answered in these manuals
What is the function of the OE input?
The output-enable (OE) input can be used to disable the device so that the buses are effectively isolated.
How is data direction controlled?
Data transmission direction depends on the logic level at the direction-control (DIR) input.
How should the output‑enable (OE) pin be handled during power‑up?
OE should be tied to VCC through a pull‑up resistor to ensure a high‑impedance state.

What input voltage range is allowed for TTL‑compatible operation?
Inputs are TTL‑voltage compatible, typically from –0.5 V to VCC + 0.5 V.
