SN74LVC2T45DCUR

Translators, Level Shifters Overview

The SN74LVC2T45DCUR is a dual-bit, dual-supply bus transceiver from Texas Instruments featuring configurable voltage translation and three-state outputs. It operates within a supply voltage range of 1.65V to 5.5V on both ports. The device supports asynchronous communication between two data buses with maximum data rates up to 420Mbps at 3.3V to 5V conversion. It utilizes an SM8 (SSOP-8) surface-mount package and includes VCC isolation to prevent high-impedance states when inputs are grounded.

Translators, Level Shifters Feature Summary

• Configurable dual-rail design supporting independent power supply voltages for each port
• VCC isolation feature ensures high-impedance state if either VCC input is grounded
• Supports partial power-down mode via Ioff circuitry to prevent backflow current damage

Translators, Level Shifters Applications

• Personal electronics systems requiring low-voltage bidirectional translation
• Industrial control interfaces utilizing mixed voltage logic levels
• Enterprise networking equipment connecting disparate voltage domains
• Telecommunications infrastructure managing asynchronous data bus communication

Translators, Level Shifters Procurement Notes

Verify the specific suffix 'DCUR' corresponds to the SM8 package and tape-and-reel orientation required for your assembly line. Confirm RoHS compliance status and lead-free manufacturing details against the latest manufacturer datasheet revision. Ensure ESD handling protocols are followed during storage and installation to maintain component integrity.

Translators, Level Shifters Selection Notes

Select this component when designing circuits that require bidirectional level shifting between 1.65V and 5.5V domains. It is suitable for applications needing VCC isolation protection and low quiescent current. Consider the SM8 package dimensions for PCB layout constraints and verify that the 420Mbps data rate meets system timing requirements.

Translators, Level Shifters Part Context

This part belongs to the SN74LVC2T45 family of dual-bit bus transceivers. It shares functional similarities with the SN74AVC2T45 series but differs in speed and voltage specifications. The DCUR suffix indicates a specific reel packaging format within the broader LVC logic family designed for portable and battery-powered applications.

Translators, Level Shifters Replacement Considerations

SN74LVC2T45DCTT offers identical electrical characteristics in a different reel packaging format. SN74LVC2T45DCU provides the same functionality in a VSSOP-8 package variant. Verify pinout compatibility and thermal performance before substituting these alternatives.
