74AC240SJX

Buffers, Drivers, Receivers, Transceivers Overview

The Fairchild Semiconductor 74AC240SJX is an octal buffer and line driver belonging to the AC logic series. It features eight inverting inputs with three-state outputs housed in a 20-pin SOP package. The device operates within a supply voltage range of 2 V to 6 V, supporting low-level output currents of 24 mA and high-level output currents of -24 mA. Propagation delay is specified at 8 ns at 3.3 V and 6.5 ns at 5 V. Static current consumption is 4 uA, and it functions reliably across temperatures from -40 C to +85 C.
