74FST3244DT

Buffers, Drivers, Receivers, Transceivers Overview

The onsemi 74FST3244DT is an 8-bit bus switch designed for high-speed data routing applications. It operates within a supply voltage range of 1.65V to 3.6V, supporting low-voltage logic systems. The device features eight independent bidirectional switches with active pull-up resistors and open-drain outputs, ensuring defined states during power-down conditions. It provides low on-resistance and fast switching speeds, making it suitable for portable electronics and battery-powered devices where power efficiency and signal integrity are critical.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Bidirectional data transfer capability across eight independent channels
• Active pull-up resistors maintain defined output states during power-off
• Low on-resistance minimizes signal attenuation and power loss
• Open-drain architecture supports mixed-voltage domain interfacing

Buffers, Drivers, Receivers, Transceivers Applications

• Portable consumer electronics requiring low-power signal switching
• Battery-operated devices needing efficient voltage level translation
• High-speed data buses in mobile communication equipment
• System boards requiring isolated signal routing between voltage domains

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'DT' corresponds to the TSSOP-20 package and tape-and-reel quantity as per the official datasheet. Confirm RoHS compliance status and lead times directly with authorized distributors. Ensure storage conditions meet moisture sensitivity level requirements before soldering. Cross-reference ordering information with the manufacturer's latest catalog to avoid obsolete packaging variants.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when bidirectional switching with defined power-down states is required. The active pull-ups distinguish it from standard switches lacking internal biasing. Consider the 1.65V minimum supply for compatibility with modern low-voltage logic families. Evaluate thermal performance if operating near maximum current limits in dense PCB layouts.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the FST (Fast Switching Technology) family, optimized for speed and low power consumption. It complements onsemi's broader portfolio of logic switches and bus transceivers. The 74FST series targets applications demanding faster transition times than standard CMOS while maintaining lower power dissipation than older bipolar technologies.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Check for direct pin-compatible alternatives such as the 74FST3244MT or similar FST-series parts from other manufacturers. Verify that substitute components support the same 1.65V to 3.6V operating range and possess equivalent active pull-up characteristics. Ensure package dimensions match the existing footprint to avoid mechanical rework.
