74LVC4T3144PWJ

Overview

The Nexperia 74LVC4T3144PWJ is a 4-bit dual-supply level translating buffer with 3-state outputs, housed in a TSSOP14 package. It translates three inputs from VCC(A) to VCC(B) and one input from VCC(B) to VCC(A). Operating voltages for both ports range from 1.2 V to 5.5 V. Maximum data rates reach 200 Mbps during 3.3 V to 5.0 V translation. The device supports partial power-down via IOFF circuitry and operates within an ambient temperature range of -40 °C to +125 °C.

Feature Summary

• Dual-supply architecture supporting independent voltage domains
• Integrated IOFF circuitry prevents backflow current during power-down
• Suspend mode automatically disables outputs when supply rails are grounded

Applications

• Unidirectional logic level-shifting between mixed-voltage systems
• Partial power-down applications requiring isolation
• Interfaces connecting microcontrollers to peripherals operating at different voltage levels

Procurement Notes

Verify the specific ordering suffix against official Nexperia documentation to confirm package type and temperature grade. Ensure compatibility with system voltage requirements before integration. Confirm RoHS compliance status through authorized distributors. Validate pinout alignment with PCB layout specifications.

Selection Notes

Select this component for designs requiring bidirectional voltage translation between two distinct power domains. The asymmetric channel configuration suits applications needing three signals translated in one direction and one in the reverse. Verify that the required data rate falls within the specified limits for the target voltage translation pair.

Part Context

This device belongs to the 74LVC family of low-voltage CMOS logic. It functions as a buffer and line driver designed for high-speed digital interfaces. The TSSOP14 package provides a compact solution for surface-mount assembly. It complements other level translators by offering dedicated asymmetric translation capabilities.

Replacement Considerations

Check for direct equivalents such as the 74AVC4T3144GU12X or 74LVC4T3144PW-Q10J. Verify pin compatibility and electrical specifications before substitution.
