74AVCH2T45GF,115

Overview

The Nexperia 74AVCH2T45GF,115 is a dual-bit, dual-supply voltage level translator and transceiver featuring 3-state outputs. It enables bidirectional level translation between 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)). It supports maximum data rates up to 500 Mbps depending on the voltage translation configuration.

Feature Summary

• Bidirectional level translation with configurable direction via DIR pin
• Partial power-down protection using IOFF circuitry to prevent backflow current
• Active bus hold circuitry to maintain valid logic levels on floating inputs
• Suspend mode operation when either supply rail is at GND level

Applications

• Interfacing digital systems operating at different voltage levels
• Partial power-down applications requiring isolation during power loss
• Bidirectional data buses in mixed-voltage embedded designs

Procurement Notes

Verify the GF suffix corresponds to the specific XSON8 package variant required for your PCB layout. Confirm that the ordering information matches the desired temperature range and package dimensions against the official datasheet before finalizing procurement orders.

Selection Notes

Select this component when designing interfaces between systems with independent power supplies. Ensure both VCC(A) and VCC(B) remain within the 0.8 V to 3.6 V range. Consider the propagation delay characteristics relative to your system's timing requirements and verify compatibility with JEDEC standards for your target voltage nodes.

Part Context

This part belongs to the 74AVCH series of advanced CMOS logic devices. It is designed for high-speed applications requiring reliable voltage translation. The device is specified over extended temperature ranges, supporting industrial and automotive environments where robust signal integrity is critical.

Replacement Considerations

Check for compatible parts such as 74AVCH2T45DC or 74AVCH2T45GT if package variations are acceptable. Verify pinout compatibility and electrical specifications before substituting.
