SN74F125N

Buffers, Drivers, Receivers, Transceivers Overview

The SN74F125N 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, each with a dedicated output-enable input. High-level output current reaches -15 mA, while low-level output current achieves 64 mA. Propagation delays are specified at 7.5 ns maximum from input to output and 8 ns maximum for enable/disable transitions.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Provides four independent non-inverting buffers with 3-state outputs
• Enables direct connection to bus lines or memory address registers
• Features TTL-compatible inputs for logic interfacing

Buffers, Drivers, Receivers, Transceivers Applications

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix 'N' corresponds to the PDIP-14 package and tube packaging configuration. Confirm RoHS compliance status and lead finish details via the manufacturer's official documentation before procurement. Ensure the application environment remains within the specified 0°C to 70°C operating temperature range.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems requiring high-drive capability for bus structures. The F-series technology offers faster switching speeds compared to standard LS equivalents. Verify that the required 64 mA low-level sink current meets the load requirements of the destination circuitry.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the SN74F series of high-speed TTL logic devices. It serves as a functional equivalent to other quadruple bus buffers in the industry but utilizes Texas Instruments' specific bipolar process technology. The N suffix designates the through-hole plastic dual in-line package variant.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Compatible substitutes include the SN74LS125 for lower speed requirements and the SN74ACT125 for CMOS compatibility. Verify pinout consistency and electrical parameter alignment before substitution.
