74AHCT245APWJ

Buffers, Drivers, Receivers, Transceivers Overview

The Nexperia 74AHCT245APWJ is an octal bus transceiver with 3-state outputs, designed for TTL-compatible interfaces. It operates within a supply voltage range of 4.5 V to 5.5 V and supports mixed-mode voltage operation on all ports. The device features overvoltage tolerant inputs up to 5.5 V and includes Schmitt-trigger action for noise immunity. Typical propagation delay is 3.0 ns at 5 V. It incorporates IOFF circuitry for partial power-down applications, preventing backflow current. The component is specified for ambient temperatures from -40 °C to +125 °C and housed in a TSSOP20 package.
