74ACT125PC

Buffers, Drivers, Receivers, Transceivers Overview

The Fairchild Semiconductor 74ACT125PC is a quad buffer and line driver belonging to the 74ACT logic series. It features four independent non-inverting buffers with three-state outputs, housed in a 14-pin plastic dual in-line package (PDIP-14). The device operates within a supply voltage range of 4.5 V to 5.5 V. Key electrical characteristics include a propagation delay of 9 ns at 5 V, high-level output current of -24 mA, low-level output current of 24 mA, and maximum static current of 2 µA. It supports an industrial operating temperature range from -40°C to +85°C.
