MC74HC125ADTR2G

Overview

The MC74HC125ADTR2G is a quad buffer and line driver from the HC logic series, manufactured by onsemi. It features four non-inverting inputs with three-state outputs, operating within a supply voltage range of 2 V to 6 V. The device utilizes a TSSOP-14 surface-mount package. Key electrical parameters include a high-level output current of -7.8 mA and a low-level output current of 7.8 mA. Static current is specified at 4 uA, with a maximum power dissipation of 450 mW. Propagation delay varies from 90 ns at 2 V to 15 ns at 6 V. The component supports an operating temperature range from -55 C to +125 C.

Feature Summary

• Provides four independent non-inverting buffer channels with three-state control for bus-oriented applications.
• Operates across a wide supply voltage range from 2 V to 6 V, ensuring compatibility with various digital logic families.
• Features robust output drive capabilities with defined high and low level currents suitable for driving loads.

Applications

• Bus-oriented memory and signal switching
• Clock distribution buffers
• Driving capacitive loads in digital systems

Procurement Notes

Verify the specific ordering suffix ADTR2G to confirm the TSSOP-14 package and reel packaging configuration. Ensure the procurement documentation references the active status of the MC74HC125A series. Confirm RoHS compliance details through official manufacturer datasheets or certified component databases prior to finalizing acquisition.

Selection Notes

Select this component when a quad non-inverting buffer with three-state functionality is required for 2 V to 6 V logic systems. The HC series offers standard CMOS performance characteristics. Consider the TSSOP-14 package constraints for PCB layout. Verify that the propagation delay specifications meet the timing requirements of the target application circuit.

Part Context

This part belongs to the MC74HC125A family of quad buffers with 3-state outputs. It is part of onsemi's broader 74HC logic portfolio, designed for high-speed CMOS operations. The device serves as a fundamental building block for digital signal routing and isolation in complex integrated circuits.

Replacement Considerations

Compatible substitutes include other quad 3-state buffers from the same logic family, such as the MC74HC125DTR2G in alternative packages. Cross-reference pinouts and electrical specifications carefully to ensure functional equivalence without modifying existing board designs.
