CD74HCT125M

Overview

The CD74HCT125M is a high-speed CMOS logic quad buffer with three-state outputs manufactured by Texas Instruments. It operates within a supply voltage range of 4.5 V to 5.5 V and supports an operating temperature range from -55 °C to +125 °C. The device utilizes a 14-pin Small Outline Integrated Circuit (SOIC) package, specifically identified as SOP14 with a .25-inch body width. It functions as a unidirectional bus driver controlled by a low-enable signal.

Feature Summary

• Provides four independent buffering channels for signal transmission
• Features three-state output capability for bus line management
• Operates using high-speed CMOS technology compatible with HCT logic standards

Applications

• Bus driver applications in digital systems
• Signal buffering between logic circuits
