74LVC2T45HK3-7

Translators, Level Shifters Overview

The 74LVC2T45HK3-7 is a dual-bit, dual-supply translating transceiver with tri-state outputs manufactured by Diodes Incorporated. It facilitates bidirectional voltage translation between logic domains ranging from 1.2V to 5.5V. The device features an independent direction control pin (DIR) referenced to VCC(A), allowing data flow configuration between Port A and Port B. It supports maximum data rates up to 420Mbps for 3.3V to 5V translations. The component operates within ambient temperatures of -40°C to +85°C or -40°C to +125°C and utilizes the X2-DFN1410-8 package.

Translators, Level Shifters Feature Summary

• Dual-port architecture enabling universal low-voltage translation across independent power rails
• IOFF feature ensures high-impedance state during partial power-down to prevent backflow currents
• Direction control input allows configurable data flow between Port A and Port B
• High noise immunity with ESD protection exceeding JESD 22 standards

Translators, Level Shifters Applications

• Voltage level translation between logic types operating at different voltages
• Power-down signal isolation in multi-domain systems
• Portable electronics such as cell phones, tablets, and e-readers
• Networking equipment including routers and gateways
• Computer peripherals and storage devices like hard drives

Translators, Level Shifters Procurement Notes

Verify the specific ordering suffix HK3 corresponds to the X2-DFN1410-8 package when sourcing. Confirm RoHS compliance and halogen-free status requirements against project specifications. Ensure supply chain channels are authorized to guarantee product authenticity and adherence to standard terms of sale.

Translators, Level Shifters Selection Notes

Select this component for applications requiring bidirectional translation between any voltages within the 1.2V to 5.5V range. Consider the X2-DFN1410-8 package dimensions for PCB layout constraints. Evaluate thermal resistance characteristics if operating near maximum temperature limits. Verify that the required data rate aligns with the specific voltage translation scenario.

Translators, Level Shifters Part Context

This part belongs to the 74LVC series of logic integrated circuits designed for low-voltage CMOS applications. It functions as a bus transceiver specifically engineered for asynchronous communication between buses operating at different voltage levels. The device integrates direction control and tri-state capabilities into a compact surface-mount form factor.

Translators, Level Shifters Replacement Considerations

The 74LVC2T45RA3-7 serves as a functional substitute utilizing the X2-DFN1210-8 package instead of the X2-DFN1410-8 format.
