SN74LVT125DRG4

Buffers, Drivers, Receivers, Transceivers Overview

The SN74LVT125DRG4 is a 3.3-V ABT quadruple bus buffer with 3-state outputs manufactured by Texas Instruments. It operates within a supply voltage range of 2.7 V to 3.6 V and features TTL-compatible CMOS inputs. The device provides four non-inverting channels in an SOIC-14 package. Key electrical parameters include a propagation delay of 2.1 ns at 3.3 V, a high-level output current of -32 mA, and a low-level output current of 64 mA. It functions within an operating temperature range of -40°C to +85°C.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Provides 3.3-V ABT technology for low-voltage operation while maintaining TTL interface compatibility with 5-V systems.
• Features 3-state outputs that allow direct connection to bus lines without additional pull-up or pull-down resistors.
• Includes bus-hold circuitry to maintain a valid logic level when no signal is actively driving the line.

Buffers, Drivers, Receivers, Transceivers Applications

• Buffering memory and data buses in 3.3-V microprocessor systems
• Driving capacitive loads on communication buses
• Interface bridging between 3.3-V logic and 5-V tolerant environments

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix DRG4 corresponds to the SOIC-14 package and tape-and-reel packaging configuration. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure the ordering part number matches the required temperature grade and pinout specifications for your PCB layout.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing 3.3-V systems requiring bus buffering with TTL input compatibility. The ABT technology offers improved performance over standard LVT families. Consider the SOIC-14 package constraints and thermal characteristics relative to your board space and power dissipation requirements.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the SN74LVTH125 family of quadruple bus buffers. It is distinct from the SN74LVT125 series which may lack specific ABT enhancements or bus-hold features depending on the revision. The DRG4 suffix specifically denotes the surface-mount SOIC package variant produced by Texas Instruments.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Direct substitutes include other SN74LVTH125 variants with compatible pinouts. Verify functional equivalence regarding bus-hold capabilities and output drive strength before swapping components.
