Product Introduction

Overview

The 74AHC245PW,112 is an octal bus transceiver with 3-state outputs, manufactured by Nexperia USA Inc. This device is part of the 74AHC245 and 74AHCT245 series, designed to facilitate bidirectional data transmission between two buses. 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.
