74AVC2T45GD,125

Overview

The Nexperia 74AVC2T45GD,125 is a dual-bit, dual-supply voltage level translator and transceiver housed in an X2SON8 package (SOT1233-2). It supports bidirectional data translation between supply voltages 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 transmission flow, IOFF circuitry for partial power-down applications, and a suspend mode that forces high-impedance states when either supply is at ground potential.

Feature Summary

• Enables bidirectional voltage level 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.
• Includes IOFF circuitry to disable outputs and prevent damaging backflow current during partial power-down conditions.
• Provides a suspend mode that places both ports in a high-impedance OFF-state when one or both supply voltages are at GND level.

Applications

• Bidirectional logic level-shifting between systems operating at different voltage levels
• Partial power-down applications requiring protection against backflow current
• Interfaces connecting low-voltage microcontrollers to peripherals with varying supply requirements

Procurement Notes

Verify the specific ordering suffix GD,125 corresponds to the X2SON8 package variant SOT1233-2. Confirm the temperature range specification matches the design requirement of -40 °C to +85 °C. Ensure the DIR pin configuration aligns with the system's direction control logic. Check for any recent Product Change Notifications regarding marking codes or assembly changes.

Selection Notes

Select this component when designing interfaces that require bidirectional translation between dual supplies within the 0.8 V to 3.6 V range. The X2SON8 package offers a compact footprint suitable for space-constrained PCB layouts. Consider the IOFF functionality if the application involves partial power-down scenarios where preventing backflow is critical. Verify that the required data rates and propagation delays meet the system timing constraints.

Part Context

This part belongs to the 74AVC2T45 family of dual-bit, dual-supply translators. The 'GD' suffix specifically denotes the X2SON8 plastic thermal enhanced extremely thin small outline package with dimensions of 1.35 x 0.8 x 0.32 mm. This family provides solutions for translating between various low-voltage nodes while maintaining high noise immunity and compliance with JEDEC standards.
