SN74F125DR

Buffers, Drivers, Receivers, Transceivers Overview

The SN74F125DR 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.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix 'DR' corresponds to the tape-and-reel packaging format required for automated assembly processes. Confirm that the active production status aligns with long-term availability needs, as component lifecycle stages can impact future supply continuity. Ensure compatibility with existing PCB footprints designated for the SOIC-14 package variant.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems requiring robust bus buffering with defined 3-state capabilities. The F-series technology offers specific drive strengths suitable for moderate-speed digital interfaces. Consider the operating temperature range and voltage specifications to ensure alignment with the target application environment and power supply constraints.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the SN74F125 family of quadruple bus buffer gates. It is distinct from other variants like the SN74AHC125 or SN74ABT125 due to its specific bipolar F-series technology and associated electrical characteristics. The DR suffix indicates a specific manufacturing configuration optimized for high-volume surface-mount production environments.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Direct pin-compatible substitutes within the same logic family include the SN74F125D (tube packaging). Cross-family replacements such as the SN74AHC125 or SN74ABT125 require careful evaluation of voltage levels, drive currents, and propagation delays to ensure functional equivalence.
