74ACTQ244SJ

Buffers, Drivers, Receivers, Transceivers Overview

The onsemi 74ACTQ244SJ is an octal buffer and line driver featuring 3-STATE outputs, designed for memory address driving, clock distribution, and bus-oriented transmission or reception. It utilizes Quiet Series technology to ensure quiet output switching and improved dynamic threshold performance. The device incorporates GTO output control and an undershoot corrector alongside a split ground bus architecture. Operating at a supply voltage of 4.5V to 5.5V, it provides enhanced PC board density and faster propagation delays compared to standard AC/ACT244 devices.
