74ACT240SC

Buffers, Drivers, Receivers, Transceivers Overview

The Fairchild Semiconductor 74ACT240SC is an octal buffer and line driver featuring inverting 3-state outputs. It belongs to the AC/ACT logic series, designed for memory address driving, clock distribution, and bus-oriented transmission or reception applications. The device provides improved printed circuit board density by reducing ICC and IOZ currents by 50% compared to standard equivalents. Outputs are capable of sourcing and sinking 24mA, while inputs remain TTL-compatible.
