SN74F125DRG4

Buffers, Drivers, Receivers, Transceivers Overview

The SN74F125DRG4 is a quadruple bus buffer gate with 3-state outputs manufactured by Texas Instruments. It operates within a supply voltage range of 4.5 V to 5.5 V and supports an operating temperature range of 0°C to 70°C. The device features four independent non-inverting line drivers housed in a 14-pin SOIC package. Electrical characteristics include a high-level output current of -15 mA and a low-level output current of 64 mA at 5 V. Propagation delays are specified as 7.5 ns maximum for both high-to-low and low-to-high transitions under standard test conditions.

• Driving bus lines
• Buffering memory address registers

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify that the ordering suffix 'R' corresponds to tape-and-reel packaging and 'G4' indicates lead-free and RoHS compliance per manufacturer standards. Confirm the specific package drawing (D) matches the required footprint dimensions. Ensure the component status is active for production use, as obsolete variants may lack long-term availability guarantees.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component for applications requiring F-series speed performance with a fixed 5 V logic interface. The device is suitable for systems where a 4.5 V to 5.5 V supply rail is available. Consider the 14-pin SOIC form factor for surface-mount assembly constraints. Evaluate thermal dissipation requirements based on the package thermal impedance if multiple units operate simultaneously.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the SN74F125 family of quadruple bus buffer gates. It shares functional compatibility with other members of the series but differs in packaging and manufacturing revisions. The DRG4 designation specifically identifies the tape-and-reel, lead-free variant in the SOIC-14 package, distinguishing it from tube-packaged or older generation equivalents.

Buffers, Drivers, Receivers, Transceivers FAQ

How is the output state controlled?

Each output is disabled when its associated output-enable (OE) input is high. When OE is low, the output follows the A input.

What is the recommended operating supply voltage?

The recommended operating supply voltage (VCC) ranges from 4.5 V to 5.5 V, with a nominal value of 5 V.
