74AVC2T45GT,115

Overview

The Nexperia 74AVC2T45GT,115 is a dual-bit, dual-supply voltage level translator and transceiver housed in an XSON8 package (SOT833-1). It supports bidirectional data translation between two independent supply domains, VCC(A) and VCC(B), both ranging from 0.8 V to 3.6 V. The device features a direction control input (DIR) to manage transmission flow between ports A and B. It includes IOFF circuitry for partial power-down protection and a suspend mode that forces high-impedance states when either supply is at GND. The component operates within a temperature range of -40 °C to +125 °C.

Feature Summary

• Bidirectional level translation between dual supply domains
• IOFF circuitry prevents backflow current during partial power-down
• Suspend mode ensures high-impedance state on low supply
• Complies with JEDEC standards for various low-voltage nodes

Applications

• Partial power-down applications requiring isolation
• Translation between low voltage nodes such as 0.8 V, 1.2 V, 1.5 V, 1.8 V, 2.5 V, and 3.3 V
• Systems requiring controlled bidirectional data transmission via DIR pin

Procurement Notes

Verify the ordering suffix GT corresponds to the XSON8 package (SOT833-1) and the -40 °C to +125 °C temperature range. Confirm the specific revision of the product data sheet matches the required specifications. Ensure compatibility with system ground references and supply voltage limits before integration.

Selection Notes

Select this component for designs requiring dual-supply level shifting with explicit direction control. It is suitable for applications needing robust protection against backflow currents during power-down sequences. Consider the XSON8 package constraints for PCB layout and thermal dissipation requirements relative to the maximum power dissipation derating curves provided in the datasheet.

Part Context

This part belongs to the 74AVC series of logic ICs, specifically designed as voltage level translators. It shares functional similarities with other dual-bit translators but is distinguished by its specific package type and extended industrial temperature rating. The AVCH variant offers similar functionality but may differ in specific electrical characteristics or package options.
