Manufacturer Part Number

SN74LVC1T45DBVTG4

Description

Bidirectional voltage level translator IC by Texas Instruments. Provides reliable voltage shifting for digital signals. Offers fast data rate of 420Mbps in a small SOT-23-6 package. RoHS3 compliant and suitable for compact or densely populated PCBs.

Specifications

1 channel (bidirectional), 1 circuit. Translation voltage range VCCA: 1.65V to 5.5V, VCCB: 1.65V to 5.5V. Output type is tri-state and non-inverted. Maximum data rate of 420Mbps. Operating temperature from -40°C to +85°C. Surface mount with SOT-23-6 case. Moisture Sensitivity Level 1, unlimited floor life.

Device Structure

Single-circuit integrated circuit. SOT-23-6 surface-mount package. Supports bidirectional signal translation. Tri-state logic output.

Performance Characteristics

Handles voltage-level translation between different logic circuits. High-speed data rate up to 420Mbps. Wide voltage compatibility for both sides (1.65V to 5.5V). Low power operation. Robust operation over industrial temperature range.

Application Environments

Used in systems needing logic-level voltage matching, such as interfaces between microprocessors and FPGAs, portable devices, consumer electronics, industrial controls, and communication equipment.

Selection Guidelines

Choose this model when compact size, high speed, and wide input/output voltage flexibility are needed. Suitable for designs requiring voltage translation in both directions and low-power applications. Check compatibility with application voltage levels and speed.

Usage Considerations

Ensure voltage supplies (VCCA and VCCB) are set correctly for proper translation. Observe ESD handling guidelines. Confirm thermal and soldering profiles match device requirements. Check that channel direction matches translation needs. Not recommended for new designs as the part is discontinued; consider alternatives if starting a new project.
