SN74LVC2T45DCUTE4

Translators, Level Shifters Overview

The SN74LVC2T45DCUTE4 is a dual-bit, dual-supply bus transceiver from Texas Instruments' LVC logic series. It features configurable voltage translation between two independent power rails ranging from 1.65 V to 5.5 V. The device supports bidirectional data transfer with a maximum data rate of 420 Mbps when translating between 3.3 V and 5 V systems. It operates within an ambient temperature range of -40°C to +85°C and utilizes a VSSOP-8 package.

Translators, Level Shifters Feature Summary

• Configurable dual-rail design allowing independent power supply settings for each port across the full 1.65 V to 5.5 V range
• Vcc isolation capability ensures both ports enter a high-impedance state if either Vcc input is grounded
• Supports partial power-down mode via Ioff circuitry to prevent back-current damage during standby
• Direction control (Dir) input logic level activates specific port outputs based on Vcca power supply

Translators, Level Shifters Applications

• Personal electronics requiring low-voltage interconnects
• Industrial control systems needing robust signal translation
• Enterprise infrastructure equipment
• Telecommunications network devices

Translators, Level Shifters Procurement Notes

Verify the DCUT suffix indicates cut-tape packaging rather than reel-only supply. Confirm RoHS compliance status through official documentation as indicated by the E4 suffix. Ensure the VSSOP-8 footprint matches the target PCB layout dimensions. Check for any specific handling requirements related to moisture sensitivity levels before assembly.

Translators, Level Shifters Selection Notes

Select this component for applications requiring asynchronous communication between buses operating at different voltage levels. The LVC series offers CMOS and TTL compatible inputs suitable for mixed-logic environments. Consider the 3-state output capability for bus sharing scenarios. Evaluate the propagation delay specifications against system timing requirements to ensure signal integrity.

Translators, Level Shifters Part Context

This part belongs to the SN74LVC2T45 family of dual-supply bus transceivers. The E4 suffix typically denotes lead-free and RoHS-compliant manufacturing variations within the Texas Instruments portfolio. It shares functional characteristics with other members like the SN74LVC2T45DCU but may differ in packaging or environmental certifications.

Translators, Level Shifters Replacement Considerations

SN74LVC2T45DCUT serves as a direct functional substitute within the same series. SN74AVC2T45DCUTG4 offers faster performance but requires lower voltage supplies. Verify pin compatibility and electrical parameters before swapping components in existing designs.
