SN74LV4320AGKFR

Specialized Overview

The SN74LV4320AGKFR is a dual-supply bus transceiver from Texas Instruments designed for level translation between 1.65V and 5.5V logic domains. It features two independent bidirectional channels, allowing flexible data flow control via separate direction pins. The device utilizes CMOS technology and operates within a supply voltage range of 1.65V to 5.5V on both ports. It is housed in a 16-pin VQFN package with a 0.5mm pitch, suitable for space-constrained applications. Key electrical characteristics include low ON resistance and high noise immunity, ensuring reliable signal integrity during voltage conversion processes.

Specialized Feature Summary

• Dual independent bidirectional channels for simultaneous level translation
• Supports voltage translation between 1.65V and 5.5V domains
• Separate direction control pins for each channel

Specialized Procurement Notes

Verify the specific suffix 'GKFR' against the manufacturer's current datasheet to confirm package type and tape/reel specifications. Check for obsolescence status as Texas Instruments frequently updates product lifecycles. Ensure compatibility with your PCB footprint for the 16-VQFN package. Confirm RoHS compliance details if required by your manufacturing standards.

Specialized Selection Notes

Select this component when bidirectional level shifting between 1.65V and 5.5V is required. Consider the 16-VQFN package size for board space constraints. Evaluate the need for separate direction control per channel versus global control options. Compare propagation delay specifications against your system timing requirements to ensure adequate performance margins.

Specialized Part Context

This part belongs to Texas Instruments' Widebus+ family of level translators. It complements other LV series devices by providing robust voltage translation capabilities. The SN74LV4320A series is designed for high-volume consumer applications requiring reliable interface solutions between varying voltage domains.

Specialized Replacement Considerations

Check for direct pin-to-pin replacements such as the SN74LV4320AIDR or SN74LV4320APWR depending on package preference. Verify functional equivalence regarding voltage ranges and channel independence before substitution.
