74AC540SJ

Buffers, Drivers, Receivers, Transceivers Overview

The onsemi 74AC540SJ is an octal buffer and line driver featuring inverting outputs with three-state capability. Manufactured using silicon gate CMOS technology, it operates within a supply voltage range of 2 V to 6 V. The device provides high drive currents of 24 mA at both logic high and low states. It exhibits propagation delays of 7.5 ns at 3.3 V and 6 ns at 5 V. Designed for surface-mount applications, it is housed in a 20-pin SOIC package and supports operation across temperatures from -40°C to +85°C.
