74LVC2T45GM,125

Translators, Level Shifters Overview

The Nexperia 74LVC2T45GM,125 is a dual-bit translating transceiver with 3-state outputs. It features two 2-bit input-output ports (nA and nB), a direction control input (DIR), and dual supply pins (VCC(A) and VCC(B)). Both supplies operate between 1.2 V and 5.5 V. The device supports bidirectional level translation between low voltage nodes including 1.2 V, 1.5 V, 1.8 V, 2.5 V, 3.3 V, and 5.0 V. Pins nA and DIR are referenced to VCC(A), while pins nB are referenced to VCC(B).

Translators, Level Shifters Feature Summary

• Bidirectional level translation capability between different voltage domains.
• Supports partial power-down applications using IOFF circuitry to prevent backflow current.
• Includes suspend mode functionality when either supply voltage is at GND level.

Translators, Level Shifters Applications

• I²C bus interfaces
• Cell phone communication modules
• LCD TV signal processing
• Set-top box data transmission
• Personal computing peripheral connections

Translators, Level Shifters Procurement Notes

Verify the specific package suffix GM corresponds to the required XSON8 footprint during procurement. Confirm that the ordering code includes the correct temperature range designation for the target application environment. Ensure compatibility with existing PCB layout constraints regarding the extremely thin small outline package dimensions before finalizing orders.

Translators, Level Shifters Selection Notes

Select this component when interfacing logic circuits operating at distinct voltage levels within the 1.2 V to 5.5 V range. The dual-supply architecture allows independent power domain management. Consider the 3-state output feature for bus sharing applications. Evaluate propagation delay requirements against the specific voltage translation scenario to ensure signal integrity.

Translators, Level Shifters Part Context

This device belongs to the 74LVC family of low-voltage CMOS logic components manufactured by Nexperia. It functions as a translating transceiver designed for mixed-voltage system integration. The part provides a compact solution for connecting digital subsystems that require voltage level shifting without external discrete components.

Translators, Level Shifters Replacement Considerations

The 74LVCH2T45 series serves as a functional alternative offering active bus hold circuitry. Verify pinout compatibility and electrical specifications before substitution. Check if the bus hold feature is required for the specific application design.
