SN74HC125DRE4

Buffers, Drivers, Receivers, Transceivers Overview

The SN74HC125DRE4 is a quad bus buffer and line driver manufactured by Texas Instruments, belonging to the HC logic series. It features four non-inverting channels with three-state outputs housed in a 14-pin SOIC package. The device operates within a supply voltage range of 2 V to 6 V. Key electrical parameters include a high-level output current of -7.8 mA and a low-level output current of 7.8 mA. Propagation delay varies from 150 ns at 2 V to 25 ns at 6 V. The component supports surface-mount installation and functions reliably across an operating temperature range of -40°C to +85°C.
