SN74LVC2T45DCTR

Translators, Level Shifters Overview

The SN74LVC2T45DCTR is a dual-bit voltage-level translator and bus transceiver manufactured by Texas Instruments. It facilitates bidirectional data translation between two independent power domains, supporting VCCA and VCCB supply voltages ranging from 1.65V to 5.5V. The device operates with a single direction-control pin to determine signal flow. Key electrical parameters include a maximum propagation delay of 3.9ns at 5V and 4.4ns at 3.3V under standard loading conditions. It features 3-state outputs and supports an output drive current of up to 50mA. The component is housed in an 8-pin SSOP package and is rated for operation within a temperature range of -40°C to +85°C.

Translators, Level Shifters Procurement Notes

Verify the specific suffix 'CTR' corresponds to the tape-and-reel packaging format required for automated assembly processes. Confirm that the SSOP-8 package dimensions align with the target PCB footprint. Ensure the selected variant meets the necessary RoHS compliance standards for the intended market. Cross-reference the manufacturer's latest datasheet to validate any recent design or material changes.

Translators, Level Shifters Selection Notes

Select this component when interfacing logic circuits operating at different voltage levels, such as translating between 1.8V and 3.3V domains. The LVC series offers a balance of speed and low power consumption suitable for general-purpose applications. Consider the 50mA drive strength if driving moderate capacitive loads. Verify that the 1.65V minimum supply voltage covers the lowest operating rail in the design.

Translators, Level Shifters Part Context

This part belongs to the SN74LVC2T45 family of dual-supply bus transceivers. It serves as a bridge for digital signals crossing voltage boundaries without requiring complex external circuitry. The device is designed for high-density applications where space is limited, utilizing the compact SSOP-8 package to minimize board area while maintaining reliable signal integrity across varying supply voltages.

Translators, Level Shifters Replacement Considerations

The SN74LVC2T45DCTT is a functional equivalent offering the same electrical characteristics but packaged in SM8 (MSOP) instead of SSOP. Designers must verify pin-to-pin compatibility and ensure the mechanical height constraints of the application can accommodate the alternative package style.
