SN74LVC125ADBRG4

Buffers, Drivers, Receivers, Transceivers Overview

The SN74LVC125ADBRG4 is a quadruple bus buffer gate with 3-state outputs manufactured by Texas Instruments. It operates from a supply voltage of 1.65V to 3.6V and features independent line drivers for each buffer. The device accepts input voltages up to 5.5V, enabling compatibility with mixed 3.3V/5V systems. It is housed in a 14-pin SSOP package and supports operating temperatures ranging from -40°C to 85°C.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Features four independent non-inverting buffers with separate output-enable inputs
• Provides 3-state outputs that enter high-impedance when the associated OE input is high
• Inputs are overvoltage tolerant, accepting voltages up to 5.5V regardless of VCC level

• Cable modem termination systems
• IP phones: wired and wireless
• Optical modules
• Telecom base band units
• Wireless communications testers

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix 'G4' corresponds to the required lead finish and RoHS compliance status. Confirm the package type matches the design requirements, as the SN74LVC125A family includes multiple package options such as SOIC, TSSOP, and VQFN. Ensure the selected variant meets the necessary thermal resistance and moisture sensitivity ratings for the intended application environment.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when a quadruple bus buffer with 3-state control is required for low-voltage logic applications. The device is suitable for designs needing voltage translation between 3.3V and 5V domains due to its input tolerance. Consider the SSOP package dimensions and thermal characteristics during PCB layout to ensure proper heat dissipation and signal integrity.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the SN74LVC125A family of quadruple bus buffer gates. The 'DB' suffix indicates the 14-pin SSOP package, while 'G4' denotes environmental compliance. Other variants in the family include SOIC (D), TSSOP (PW), and VQFN (RGY) packages, offering flexibility for different board space and thermal management needs.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Direct replacements within the same family include SN74LVC125ADBR and SN74LVC125ADBR.A, which share identical electrical specifications and pinouts. Verify that any substitute maintains the same package style and temperature range requirements.
