MC74LVX125DR2

Overview

The MC74LVX125DR2 is a quad buffer and line driver manufactured by onsemi, belonging to the LVX logic series. It features four non-inverting channels with three-state outputs in a SOIC-14 package. The device operates within a supply voltage range of 2 V to 3.6 V. Key electrical parameters include a high-level output current of -4 mA and a low-level output current of 4 mA. Static current is specified at 4 uA, with a maximum power dissipation of 180 mW. Propagation delay is 13.6 ns at 2.7 V and 9.7 ns at 3.3 V. The operating temperature range extends from -40 C to +85 C.

Feature Summary

• Provides four independent non-inverting buffer channels for signal conditioning.
• Features three-state outputs to facilitate bus-oriented connections.
• Operates with low static current consumption suitable for battery-powered applications.

Applications

• Bus-oriented systems requiring signal buffering
• Clock distribution networks
• Memory data line drivers

Procurement Notes

Verify the exact suffix DR2 against official onsemi documentation to confirm tape-and-reel packaging and specific manufacturing lot details. Ensure compatibility with existing PCB footprints for SOIC-14 packages. Confirm RoHS compliance status through the latest datasheet revision. Check for any obsolescence notices or lifecycle changes directly from the manufacturer before finalizing procurement plans.

Selection Notes

Select this component when designing circuits that require low-voltage operation between 2 V and 3.6 V. The LVX series offers a balance of speed and power efficiency. Compare propagation delays and output drive capabilities against other LVX variants if higher performance is needed. Ensure the SOIC-14 package fits the thermal and spatial constraints of the design.

Part Context

This part belongs to the 74LVX125 family of quad buffers. It shares functional similarities with other LVX series devices but is distinct in its specific pinout and electrical characteristics. It serves as a standard solution for interfacing low-voltage logic families in digital communication systems.

Replacement Considerations

Direct substitutes may include MC74LVX125DTG or MC74LVX125MTCX, depending on required packaging such as TSSOP or SOIC. Verify pin compatibility and electrical specifications before substitution.
