Overview
The 74AHCT245PW,118 is an 8-bit bus transceiver with 3-state outputs, manufactured by Nexperia USA Inc. This device is part of the 74AHCT245 series and is designed for bidirectional data transmission. It features an output enable (OE) and a send/receive (DIR) pin for direction control, allowing the outputs to assume a high-impedance OFF-state when OE is HIGH. This makes it suitable for use in mixed voltage environments as a translator.
