SN74ALVC125PWR

Buffers, Drivers, Receivers, Transceivers Overview

The SN74ALVC125PWR is a quadruple bus buffer gate with 3-state outputs manufactured by Texas Instruments. It operates from a supply voltage range of 1.65 V to 3.6 V and features independent line drivers. The device provides ±24-mA output drive at 3.3 V and achieves a maximum propagation delay (t_pd) of 2.8 ns at 3.3 V. It is housed in a 14-pin TSSOP package and supports an operating free-air temperature range of -40 °C to 85 °C.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Features four independent non-inverting buffers with 3-state outputs for bus-oriented systems.
• Provides high-speed performance with a maximum propagation delay of 2.8 ns at 3.3 V.
• Supports robust output drive capability of ±24 mA at 3.3 V.
• Includes latch-up protection exceeding 250 mA per JESD 17 standards.

Buffers, Drivers, Receivers, Transceivers Applications

• Bus-oriented systems requiring signal buffering
• Clock drivers and timing circuits
• Memory and data register applications

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix 'PWR' corresponds to the tape-and-reel packaging format and the TSSOP-14 physical outline. Confirm that the -40 °C to 85 °C operating temperature range aligns with your system requirements, as other variants may offer extended industrial or automotive ratings. Ensure compatibility with standard surface-mount assembly processes for the PW package type.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing low-voltage logic interfaces requiring fast switching speeds and strong drive capabilities. The ALVC series is suitable for bridging different voltage domains within the 1.65 V to 3.6 V range. Consider the TSSOP package if space constraints on the PCB favor a smaller footprint compared to SOIC or SOP alternatives while maintaining similar pin counts.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the SN74ALVC125 family of quadruple bus buffers. It shares functional similarities with the SN74LVC125 but offers faster switching characteristics due to the Advanced Low-Voltage CMOS technology. The PWR suffix specifically denotes the tape-and-reel version of the TSSOP package, distinguishing it from tube-packaged variants like the SN74ALVC125PW.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Public confirmed substitute part numbers include SN74ALVC125PW and SN74ALVC125DR. These parts share identical logical functions and electrical specifications but differ in packaging style or reel quantity.
