74AVC1T45GN,132

Overview

The Nexperia 74AVC1T45GN,132 is a single-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 1-bit input-output ports (A and B), a direction control input (DIR), and dual supply pins (VCC(A) and VCC(B)). Pins A and DIR are referenced to VCC(A), while pin B is referenced to VCC(B). It supports maximum data rates up to 500 Mbit/s depending on the specific voltage translation configuration.

Feature Summary

• Bidirectional level translation capability between diverse low-voltage logic nodes
• IOFF circuitry enabling partial power-down mode operation to prevent backflow current
• Suspend mode functionality when either supply rail is at ground potential
• High noise immunity with overvoltage tolerant inputs

Applications

• Translating signals between mixed voltage domains in embedded systems
• Interfacing components operating at different supply voltages within portable devices
• Connecting peripherals with varying logic levels in industrial control environments

Procurement Notes

Verify that the ordering suffix matches the required package type, as the base part number covers multiple variants. Confirm the temperature range specification aligns with system requirements, noting that this specific variant supports extended industrial temperatures. Ensure compatibility with existing PCB footprint designs for the XSON6 package before finalizing procurement orders.

Selection Notes

Select this component when designing circuits requiring translation between widely varying low-voltage standards such as 0.8 V, 1.2 V, 1.5 V, 1.8 V, 2.5 V, and 3.3 V. It is suitable for applications demanding low power consumption and high noise immunity. Consider the XSON6 package dimensions if space-constrained layouts are necessary for the target electronic assembly.

Part Context

This device belongs to the 74AVC logic family, designed for advanced low-voltage applications. It serves as a bridge between different voltage domains without requiring external components for basic level shifting. The inclusion of IOFF support allows integration into systems where partial power-down states are critical for energy efficiency and signal integrity protection.

Replacement Considerations

Direct substitutes include other packages within the same family such as 74AVC1T45GW, 74AVC1T45GM, and 74AVC1T45GS. These alternatives share identical electrical characteristics but differ in physical package dimensions and lead configurations.
