SN74LVCC3245ADBRE4

Translators, Level Shifters Overview

The SN74LVCC3245ADBRE4 is a voltage-level translating bus transceiver manufactured by Texas Instruments. It features eight bidirectional channels with three-state outputs, designed to facilitate data transfer between different logic families. The device supports dual power supplies: VCCA operates within the 2.3 V to 3.6 V range, while VCCB accommodates voltages from 3 V to 5.5 V. This configuration enables seamless translation between low-voltage and standard CMOS logic levels. The component is housed in a 20-pin SSOP package and is rated for operation across an extended temperature range of -40°C to +85°C.

Translators, Level Shifters Feature Summary

• Supports bidirectional data transmission between two independent buses with separate supply domains
• Provides automatic direction sensing to control signal flow without external direction pins
• Features three-state outputs that isolate the bus when disabled
• Enables direct interface between 2.3V–3.6V and 3V–5.5V logic systems

Translators, Level Shifters Applications

• Connecting microprocessors operating at lower voltages to memory or peripheral devices at higher voltages
• Interfacing low-voltage controllers with standard 5V I/O ports
• Bidirectional data routing in mixed-voltage embedded systems

Translators, Level Shifters Procurement Notes

Verify the complete part number including the E4 suffix to confirm lead-free compliance and specific packaging details. Ensure the SSOP-20 package variant matches your PCB footprint requirements. Confirm that the voltage levels on both A and B ports fall within the specified operational ranges before integration. Check for any recent product change notices regarding pinout or electrical characteristics updates.

Translators, Level Shifters Selection Notes

Select this component when bidirectional level shifting is required between dissimilar voltage domains. It is suitable for applications needing automatic direction control rather than manual pin-based direction setting. Consider the SSOP-20 package constraints for board space. Verify that the input/output current capabilities meet the load requirements of the connected devices.

Translators, Level Shifters Part Context

This part belongs to the SN74LVCC3245A family of voltage-level translators. It shares functional similarities with other LVCC series devices but is distinguished by its specific dual-supply capability and bidirectional architecture. The RE4 suffix indicates environmental compliance and specific manufacturing traceability standards defined by Texas Instruments for this component line.
