SN74ALVC164245DLR

Translators, Level Shifters Overview

The SN74ALVC164245DLR is a 16-bit bidirectional level-shifting transceiver from the Texas Instruments ALVC logic family. It features two independent VCCA and VCCB power supplies, enabling voltage translation between 2.3V to 3.6V on Port A and 3V to 5.5V on Port B. The device supports data rates up to 300 Mb/s with a propagation delay of 2.4 ns at 3.3V. It operates within an extended temperature range of -40°C to +85°C and utilizes a 48-pin SSOP package.

Translators, Level Shifters Feature Summary

• Dual-supply architecture allows flexible voltage translation between low-voltage (2.5V/3.3V) and standard (3.3V/5V) logic domains.
• High-speed performance supports data transfer rates up to 300 Mb/s for demanding digital interfaces.
• Compliant with JESD17 standards, ensuring robust latch-up protection exceeding 250 mA.
• Input levels are referenced to the VCCA supply rail, simplifying interface design across different voltage environments.

Translators, Level Shifters Applications

• Mobile phones and portable consumer electronics
• Consumer appliances and white goods
• Personal digital assistants (PDAs)
• Peripherals and printer interfaces

Translators, Level Shifters Procurement Notes

Verify the specific suffix 'DLR' corresponds to the tape-and-reel packaging format required for automated assembly processes. Confirm that the 48-SSOP footprint matches the target PCB layout dimensions. Ensure the selected component meets the necessary RoHS compliance standards for the intended market region.

Translators, Level Shifters Selection Notes

Select this component when interfacing systems requiring simultaneous translation between 2.5V, 3.3V, and 5V logic families. The dual-supply design eliminates the need for external level-shifting circuits. Consider the 48-SSOP package constraints regarding board space and thermal dissipation requirements for high-density designs.
