TXB0101DCKRG4

Translators, Level Shifters Overview

The TXB0101DCKRG4 is a single-channel bidirectional voltage-level translator manufactured by Texas Instruments. It operates with dual power supplies: VCCA ranging from 1.2 V to 3.6 V and VCCB from 1.65 V to 5.5 V. The device supports data rates up to 100 Mb/s with a propagation delay of 7.4 ns. It features three-state outputs and automatic direction detection, eliminating the need for a direction control pin. Packaged in a compact SC-70 (SOT-363) footprint measuring 2.15 x 1.4 x 1 mm, it functions within an industrial temperature range of -40 °C to +85 °C.

Translators, Level Shifters Feature Summary

• Automatic direction sensing eliminates external control pins
• Supports mixed 1.2-V to 3.6-V and 1.65-V to 5.5-V I/O systems
• High-speed translation capability up to 100 Mb/s
• Three-state output configuration for bus isolation

Translators, Level Shifters Applications

• Connecting low-voltage processors to higher-voltage peripheral buses

Translators, Level Shifters Procurement Notes

Verify the suffix 'R' indicates tape-and-reel packaging. Confirm the 'G4' suffix denotes lead-free and RoHS compliance per Texas Instruments standards. Ensure the SC-70 package matches your PCB footprint requirements. Check for moisture sensitivity level constraints during assembly. Validate that the operating voltage ranges align with your specific circuit design needs.

Translators, Level Shifters Selection Notes

Select this component when a single channel of bidirectional translation is required between dissimilar voltage domains. It is suitable for applications needing high speed without dedicated direction control logic. Consider the SC-70 package size for space-constrained designs. Compare against the TXS0101 if automotive qualification or different voltage thresholds are necessary.

Translators, Level Shifters Part Context

This part belongs to the TXB01xx series of voltage translators. It shares functional similarities with the TXS0101 but lacks automotive qualification. It differs from multi-channel variants like the TXB0104 by providing only one translation path. The SC-70 package offers a smaller footprint compared to TSSOP options.
