SN74LVC2T45MDCTTEP

Translators, Level Shifters Overview

The SN74LVC2T45MDCTTEP is a dual-bit, dual-supply bus transceiver from Texas Instruments' LVC logic family. It facilitates asynchronous communication between two buses operating at different voltage levels ranging from 1.65V to 5.5V. The device features VCC isolation, ensuring high-impedance states if either supply is grounded. It supports partial power-down via Ioff and includes ESD protection exceeding JESD22 specifications. Packaged in an SM-8 (MSOP) format, it operates within a temperature range of -55°C to +125°C.

Translators, Level Shifters Feature Summary

• Dual-supply architecture with independent VCCA and VCCB rails for flexible voltage translation
• VCC isolation feature forces both ports to high impedance when any supply is grounded
• Ioff support enables partial power-down mode to prevent backflow current damage
• Direction control input activates specific port outputs for bidirectional data transfer

Translators, Level Shifters Applications

• Personal electronics requiring low-voltage level shifting
• Industrial systems utilizing mixed voltage domains
• Enterprise infrastructure equipment
• Telecommunications hardware

Translators, Level Shifters Procurement Notes

Verify the complete part number including the EP suffix, which indicates enhanced plastic packaging. Confirm the package type corresponds to the SM-8 designation. Ensure the manufacturer is Texas Instruments. Check RoHS compliance status as specified in the official datasheet. Validate the operating temperature range requirements against your specific application environment before procurement.

Translators, Level Shifters Selection Notes

Select this component when bidirectional translation between 1.65V and 5.5V domains is required. The dual-supply design allows A and B ports to track respective voltages independently. Consider the VCC isolation capability for safety-critical applications where ground faults must trigger high-impedance states. The wide operating temperature range suits harsh environments. Verify that the direction control logic aligns with system timing requirements.

Translators, Level Shifters Part Context

This device belongs to the SN74LVC2T45 series, designed for low-voltage CMOS applications. It serves as a key interface solution for connecting legacy 5V systems with modern 1.8V or 3.3V digital logic. The dual-port configuration simplifies board layout by handling two bits simultaneously. It replaces older translation methods by integrating direction control and isolation into a single compact package.

Translators, Level Shifters Replacement Considerations

Compatible substitutes include SN74LVC2T45DCUR and SN74LVC2T45DCTR. These variants share identical electrical characteristics but differ in packaging and reel specifications. Verify pin compatibility and thermal performance before substitution.
