SN74LV4320AZKFR

Specialized Overview

The SN74LV4320AZKFR is a dual-supply automatic bidirectional level-shifting translator from Texas Instruments. It facilitates voltage translation between two independent power domains, supporting input voltages from 1.65 V to 5.5 V and output voltages from 1.65 V to 5.5 V. The device features two independent channels for bidirectional data transfer. It operates within a commercial temperature range of 0°C to +70°C and is housed in a 10-pin Ultra Small Ball Grid Array (RZB) package with a pitch of 0.5 mm.

Specialized Feature Summary

• Automatic direction sensing eliminates the need for a direction control pin
• Supports bidirectional data transmission between dissimilar voltage domains
• Compatible with various memory interfaces including CompactFlash and SD cards

Specialized Applications

• Interfacing core processors to CompactFlash memory cards
• Connecting low-voltage controllers to 3.3V or 5V peripherals
• Level shifting in consumer electronics requiring mixed-voltage logic

Specialized Procurement Notes

Verify the specific suffix ZKFR against the manufacturer's current datasheet to confirm package type and tape-and-reel specifications. Ensure that the supply voltage requirements for both ports align with the target system design before integration.

Specialized Selection Notes

Select this component when bidirectional translation is required without explicit direction control signals. Confirm that the voltage levels on both sides fall within the 1.65 V to 5.5 V operating range. Consider the 10-pin RZB package constraints for PCB layout if space is limited.

Specialized Part Context

This part belongs to the SN74LV4320A family of widebus level shifters. It is designed to replace discrete resistor networks or manual switching circuits in mixed-voltage systems, simplifying board design for applications like mobile devices and embedded systems.

Specialized Replacement Considerations

Check for SN74LV4320AQKFR for automotive qualification variants. Verify pinout compatibility with other LV series translators if alternative packages are considered.
