74AHC244PW/AUJ

Buffers, Drivers, Receivers, Transceivers Overview

The NXP USA Inc. 74AHC244PW/AUJ is an octal buffer and line driver featuring three-state outputs, housed in a 20-pin TSSOP package. It operates on a supply voltage range of 2.0 V to 5.5 V. The device contains two independent four-bit buffers controlled by separate output enable inputs (1OE and 2OE). Inputs are overvoltage tolerant up to 5.5 V, allowing use as translators in mixed-voltage environments. All inputs feature Schmitt-trigger action for high noise immunity.
