74AHC244D,118

Buffers, Drivers, Receivers, Transceivers Overview

The Nexperia 74AHC244D,118 is an octal buffer and line driver featuring three-state outputs. It operates within a supply voltage range of 2.0 V to 5.5 V and supports an ambient temperature range from -40 °C to +125 °C. The device contains two independent output enable inputs (1OE and 2OE), each controlling four outputs. Inputs are overvoltage tolerant up to 5.5 V, allowing use in mixed-voltage environments. The component utilizes Schmitt-trigger action on all inputs for high noise immunity.
