74AVC2T45GN,115

Overview

The Nexperia 74AVC2T45GN,115 is a dual-bit, dual-supply voltage level translator and transceiver featuring 3-state outputs. It enables bidirectional level translation between any low-voltage nodes ranging from 0.8 V to 3.6 V. The device includes two data input-output ports (nA and nB), a direction control input (DIR), and dual-supply pins (VCC(A) and VCC(B)). Pins nA and DIR are referenced to VCC(A), while pins nB are referenced to VCC(B). A HIGH on DIR allows transmission from nA to nB, and a LOW allows transmission from nB to nA. It supports partial power-down applications using IOFF circuitry.

Feature Summary

• Supports bidirectional level translation between any low-voltage nodes within the 0.8 V to 3.6 V range.
• Features IOFF circuitry that disables outputs to prevent damaging backflow current during partial power-down.
• Includes suspend mode functionality where both ports enter high-impedance OFF-state when either supply is at GND level.

Applications

• Bidirectional logic level-shifting applications
• Unidirectional logic level-shifting applications
• Partial power-down system designs

Procurement Notes

Verify the specific ordering suffix GN corresponds to the XSON8 package with dimensions 1.2 x 1.0 x 0.35 mm and SOT1116 variant. Confirm the temperature range specification matches the -40 °C to +125 °C requirement for your application environment. Ensure compatibility with JEDEC standards JESD8-12 through JESD8-B as applicable to your voltage levels.

Selection Notes

Select this component for designs requiring flexible voltage translation across multiple low-voltage domains without fixed supply constraints. The dual-supply architecture allows independent voltage settings for each port. Consider the XSON8 package size if PCB space is limited. Verify that the DIR pin reference to VCC(A) aligns with your control logic requirements.

Part Context

This part belongs to the 74AVC2T45 family of dual-bit, dual-supply voltage level translators. The GN suffix specifically denotes the XSON8 package type (SOT1116) with body dimensions of 1.2 x 1.0 x 0.35 mm. Other variants in the family include DP (TSSOP8), DC (VSSOP8), GT (XSON8 different dimensions), GS (XSON8 different dimensions), and GX (X2SON8).
