CD74HC125MT

Overview

The CD74HC125MT is a high-speed CMOS logic quad buffer with three-state outputs manufactured by Texas Instruments. It operates within a supply voltage range of 2 V to 6 V and features four non-inverting buffers. The device utilizes a 14-pin Small Outline Integrated Circuit (SOIC) package, specifically SOP14 with a .25-inch width. It supports unidirectional data flow with low-level enable control. The component is designed for industrial temperature ranges from -55°C to +125°C and includes a load capacitance specification of 50 pF.
