74FR16541SSC

Buffers, Drivers, Receivers, Transceivers Overview

The Fairchild Semiconductor 74FR16541SSC is a 16-bit non-inverting buffer and line driver featuring three-state outputs. Packaged in a 48-pin SSOP, this device contains two independent eight-bit buffers designed for high-speed memory and address bus driving applications. The component supports operation at supply voltages up to 5.5V, providing robust signal integrity for digital logic systems requiring isolated output control and reduced power consumption during idle states.

• Memory system data bus buffering
• Address bus line driving
• Digital logic interface isolation

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the exact suffix designation when ordering, as variants such as the 'X' suffix indicate tape and reel packaging options distinct from the standard SSOP unit. Confirm manufacturer lineage, noting that Fairchild Semiconductor assets have transitioned to ON Semiconductor; ensure the source document explicitly identifies Fairchild as the producer to avoid confusion with legacy or successor part numbers. Cross-reference the datasheet revision date to confirm pinout compatibility.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems requiring 16-bit wide non-inverting buffering with controlled output impedance. The three-state feature is critical for multiplexed bus architectures where multiple drivers share common lines. Ensure the application voltage does not exceed the specified 5.5V maximum rating. Consider the SSOP package constraints regarding thermal dissipation and board space compared to larger footprint alternatives.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the 74FR series of fast CMOS logic devices produced by Fairchild Semiconductor. It serves as a specialized buffer within the broader 74xx logic family ecosystem, offering higher speed performance than standard TTL equivalents while maintaining compatible logic levels. The specific model number indicates the 16-bit width and SSOP packaging format.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Check for direct substitutes like the 74ACT16541SSC, which shares similar functional characteristics but may differ in electrical specifications such as drive current or switching speed. Verify pin-to-pin compatibility before substitution. Note that ON Semiconductor may offer equivalent parts under updated naming conventions following the acquisition of Fairchild's semiconductor business.
