SN74LV125ATDB

Buffers, Drivers, Receivers, Transceivers Overview

The SN74LV125ATDB is a quadruple bus buffer gate manufactured by Texas Instruments, featuring non-inverting logic and three-state outputs. It operates within a supply voltage range of 2.0 V to 5.5 V and supports input lines up to 3.6 V for 5-V tolerant applications. The device provides high drive capability with output currents of ±16 mA at 5 V and ±8 mA at 3.3 V. It functions reliably across an industrial temperature range from -40°C to +85°C and is housed in a TSSOP-14 package.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Provides four independent non-inverting buffers with three-state control for bidirectional bus holding
• Accepts 3.6-V inputs while operating on 5-V supplies, enabling direct interfacing between 5-V and 3.3-V systems
• Delivers strong output drive capabilities suitable for driving capacitive loads on high-speed data buses

Buffers, Drivers, Receivers, Transceivers Applications

• Bidirectional bus holding and level shifting between 5-V and 3.3-V logic domains
• Clock distribution and buffering in high-speed computing systems
• Data register and driver implementations in industrial control environments

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'A' indicates automotive qualification or specific grading per Texas Instruments documentation. Confirm the TSSOP-14 package dimensions match your PCB footprint requirements. Ensure the operating voltage range aligns with your system's power rails. Check RoHS compliance status if required for your manufacturing standards. Validate that the 3.6-V input tolerance meets your interface signal levels.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when interfacing 5-V logic with 3.3-V systems requiring robust drive strength. Consider the SN74LV125ATDB for applications needing bidirectional bus holding with low standby current. Evaluate the TSSOP-14 package for space-constrained surface-mount designs. Compare propagation delay specifications against your system timing requirements. Ensure the 3.6-V input tolerance is sufficient for your source logic levels.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the LV (Low-Voltage CMOS) family, designed for high-speed operation with reduced power consumption. It complements other bus buffer solutions like the SN74LVC125 series but offers distinct voltage tolerance characteristics. The quadruple configuration allows multiple signal paths to be managed within a single integrated circuit, simplifying board layout.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

The SN74LV125ADBR serves as a pin-compatible alternative in a SOIC-14 package. The SN74LV125APWR is available in a TSSOP-14 package with similar electrical characteristics. Verify functional equivalence regarding input voltage tolerance and output drive current before substitution.
