74AVCH2T45GN,115

Overview

The Nexperia 74AVCH2T45GN,115 is a dual-bit, dual-supply voltage level translator and transceiver housed in an XSON8 package (SOT1116). It supports bidirectional level translation between any low-voltage nodes ranging from 0.8 V to 3.6 V on both ports A and B. The device features a direction control input (DIR) to manage data flow, IOFF circuitry for partial power-down applications, and active bus hold circuitry to maintain valid logic levels on floating inputs without external resistors.

Feature Summary

• Enables bidirectional voltage level translation between independent supply domains
• Includes IOFF circuitry to prevent damaging backflow current during partial power-down
• Features active bus hold circuitry to eliminate the need for external pull-up or pull-down resistors

Applications

• Bidirectional logic level-shifting between systems with different supply voltages
• Unidirectional logic level-shifting applications
• Partial power-down mode operation in mixed-voltage designs

Procurement Notes

Verify the specific ordering suffix GN corresponds to the SOT1116 XSON8 package variant. Confirm that the required operating temperature range aligns with the -40 °C to +125 °C specification provided for this part number. Ensure design compatibility with the dual-supply architecture before procurement.

Selection Notes

Select this component when designing interfaces between mixed-voltage subsystems requiring bidirectional data transfer. The dual-supply capability allows flexible voltage node selection. Consider the XSON8 package dimensions for PCB space constraints. Verify DIR pin logic requirements for direction control implementation.

Part Context

This device belongs to the 74AVCH series of dual-supply translators. It shares functional similarities with other variants like the 74AVCH2T45GS but differs in physical packaging. The GN suffix specifically denotes the SOT1116 XSON8 package, distinguishing it from other package options within the same logical family.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Designers should consult official Nexperia resources for cross-reference information regarding alternative packages or updated revisions.
