SN74F240NSR

Buffers, Drivers, Receivers, Transceivers Overview

The SN74F240NSR is an octal buffer and line driver from the Texas Instruments SN74F logic family. It features eight inverting channels with three-state outputs, housed in a 20-pin SOIC package. The device operates within a supply voltage range of 4.5 V to 5.5 V. Key electrical characteristics include a propagation delay of 7 ns at 5 V, a low-level output current capability of 64 mA, and a high-level output current of -15 mA. It supports through-hole or surface-mount installation styles depending on the specific variant configuration.
