74AHCT17APWJ

Buffers, Drivers, Receivers, Transceivers Overview

The Nexperia 74AHCT17APWJ is a hex buffer with Schmitt-trigger inputs, designed for operation within a supply voltage range of 4.5 V to 5.5 V. It features TTL-compatible inputs and supports mixed-mode voltage operation on all ports. The device includes IOFF circuitry for partial power-down applications, preventing damaging backflow current when powered down. It operates from -40 °C to +125 °C and provides ESD protection exceeding 3000 V (HBM) and 2000 V (CDM). Latch-up performance exceeds 250 mA per JESD 78 Class II.
