74HC125DTR2G

Overview

The onsemi 74HC125DTR2G is a quad 3-state noninverting buffer manufactured using high-performance silicon-gate CMOS technology. It operates within a DC supply voltage range of 2.0 V to 6.0 V and supports an operating temperature range from -55°C to +125°C. The device features four separate active-low output enables, allowing independent control of each buffer channel. It provides an output drive capability equivalent to 15 LSTTL loads and ensures low input current characteristics typical of CMOS devices.

Feature Summary

• Provides four independent noninverting buffers with dedicated active-low output enable controls for precise bus management.
• Features high noise immunity and robust ESD protection rated at 2000 V via Human Body Model standards.
• Ensures direct interface compatibility with standard CMOS, NMOS, and TTL logic families.

Applications

• Memory address drivers
• Clock signal distribution
• Bus-oriented system interconnects

Procurement Notes

Verify the specific package suffix 'DT' corresponds to the TSSOP-14 form factor required for your PCB layout. Confirm that the RoHS compliance status aligns with your manufacturing environmental regulations. Ensure the active-low enable logic matches your system design requirements before finalizing procurement.

Selection Notes

Select this component when a quad buffer configuration with individual output control is necessary. The HC series offers a balance of speed and power consumption suitable for general-purpose digital applications. Verify that the 2.0 V to 6.0 V supply range covers your system's operational voltage needs.

Part Context

This part belongs to the 74HC family of high-speed CMOS logic devices. It shares pinout compatibility with LS125 equivalents while offering improved switching speeds and lower power dissipation. The device is designed for modern digital systems requiring reliable signal buffering and isolation.

Replacement Considerations

Check for compatible alternatives such as the 74HC125DR2G if SOIC-14 packaging is acceptable instead of TSSOP-14. Verify electrical specifications match exactly when substituting with parts from other manufacturers in the 74HC125 category.
