TCA39416DTWR

Translators, Level Shifters Overview

The TCA39416DTWR is a 2-bit bidirectional voltage-level translator designed for I3C, I2C, SMBus, and SPI applications. It operates with supply voltages (VCCA and VCCB) ranging from 0.72 V to 1.98 V, requiring VCCA ≤ VCCB. The device supports MIPI I3C speeds up to 12.5 MHz in SDR mode and 25 Mbps in HDR-DDR mode. It features internal 10-kΩ pull-up resistors on Ax and Bx pins, rise and fall time accelerators, and an OE input for disabling outputs. The DTWR suffix indicates an X2SON (8) package measuring 1 mm × 1.35 mm.

Translators, Level Shifters Feature Summary

• Auto-direction-sensing architecture eliminates the need for a direction-control pin.
• Integrated rise and fall time accelerators enhance signal slew rates for high-speed data integrity.
• Internal 10-kΩ pull-up resistors function as high-keepers when bus lines are high.
• VCC isolation ensures high-impedance states if either supply rail is at ground potential.

Translators, Level Shifters Applications

• Servers
• Wearables
• Personal electronics

Translators, Level Shifters Procurement Notes

Verify the specific ordering suffix DTWR corresponds to the X2SON (8) package configuration required for your PCB layout. Confirm that the reel packaging aligns with your automated assembly equipment specifications. Ensure design compatibility with the 0.72 V to 1.98 V operating voltage range and the mandatory VCCA ≤ VCCB constraint before finalizing procurement.

Translators, Level Shifters Selection Notes

Select this component when interfacing logic levels between devices operating within the 0.72 V to 1.98 V range. It is suitable for I3C, I2C, and SMBus buses where bidirectional translation without direction control is required. Consider the X2SON package size for space-constrained designs and verify that the system can accommodate the necessary bypass capacitors close to the power pins.

Translators, Level Shifters Part Context

This part belongs to the TCA39416 family of ultra-low-voltage translators from Texas Instruments. The family includes variants like the TCA39416DDFR, which differs primarily in packaging (SOT-23-T vs. X2SON). These devices are engineered for modern low-power interfaces, providing robust translation capabilities while maintaining compatibility with strict voltage constraints found in portable and edge computing systems.

Translators, Level Shifters Replacement Considerations

The TCA39416DDFR serves as a functional equivalent with identical electrical characteristics but utilizes an SOT-23-T (8) package instead of the X2SON (8) form factor. Verify footprint compatibility before substitution. No other direct substitutes are documented in the provided source material.
