SN74LVC2T45QDCURQ1

Translators, Level Shifters Overview

The SN74LVC2T45QDCURQ1 is a dual-supply bus transceiver from the SN74LVC2T45-Q1 series, designed for asynchronous bidirectional voltage translation between two independent buses. It operates with VCCA and VCCB supply voltages ranging from 1.65V to 5.5V, supporting logic levels of 1.8V, 2.5V, 3.3V, and 5V. The device features a data rate up to 420Mbps at 3.3V-to-5V conversion, with a propagation delay of 7.9ns. It includes Ioff support for partial power-down mode and Vcc isolation to prevent current backflow. Packaged in an 8-VSSOP (DCT) housing, it is qualified under AEC-Q100 standards for automotive applications.

Translators, Level Shifters Feature Summary

• Dual-supply architecture enabling configurable voltage translation across 1.65V to 5.5V ranges on both ports
• Vcc isolation feature ensures high-impedance state on both ports if either supply input is grounded
• Ioff circuitry supports partial power-down mode by disabling outputs to prevent damaging back-current
• Direction control (DIR) input activates specific port output based on logical level relative to VCCA

Translators, Level Shifters Applications

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

Translators, Level Shifters Procurement Notes

Verify component authenticity through authorized distribution channels. Confirm AEC-Q100 qualification status matches project requirements. Ensure packaging type aligns with assembly specifications. Check RoHS compliance documentation for regulatory adherence. Validate operating temperature range suitability for target environment conditions.

Translators, Level Shifters Selection Notes

Select this component when bidirectional translation between 1.65V and 5.5V domains is required. Consider the 420Mbps data rate capability for high-speed interface needs. Evaluate the 8-VSSOP package size against board space constraints. Verify DIR pin configuration compatibility with system control logic. Assess thermal performance within the -40°C to +125°C operational window.
