74AHCT244PW,112

Buffers, Drivers, Receivers, Transceivers Overview

The 74AHCT244PW,112 is an octal buffer and line driver with 3-state outputs manufactured by Nexperia. It operates within a supply voltage range of 4.5 V to 5.5 V. The device features TTL-compatible input levels and includes two output enable inputs (1OE and 2OE) that control four outputs each. Inputs are overvoltage tolerant up to 5.5 V. Propagation delay is typically 7.4 ns at 4.5 V to 5.5 V with a 15 pF load. The component is housed in a TSSOP20 package.
