2N7001TDCKR

Overview

The Texas Instruments 2N7001TDCKR is a single-bit dual-supply buffered voltage signal converter housed in a 5-pin SC-70 package. It translates unidirectional signals between supply rails ranging from 1.65 V to 3.6 V, supporting data rates up to 100 Mbps. The device features a maximum quiescent current of 14 µA and operates within a temperature range of –40°C to +125°C. It includes VCC isolation for high-impedance states below 100 mV, Ioff support for partial-power-down modes, and ESD protection exceeding 2000 V (HBM) and 1000 V (CDM).

Feature Summary

• Supports bidirectional voltage translation across 1.65 V to 3.6 V rails.
• Includes VCC isolation feature for automatic high-impedance output when supplies are low.
• Enables partial-power-down operation via Ioff leakage current specifications.
• Provides integrated ESD protection meeting JESD 22 standards.

Applications

• MCU/FPGA/processor GPIO translation
• Communications modules to processor translation
• Push-pull I/O buffering

Procurement Notes

Verify the specific ordering suffix 'DCKR' corresponds to the SC-70 package with tape-and-reel packaging containing 3000 units per reel. Confirm that the component status is listed as Active Production. Ensure the operating temperature range matches the required environmental conditions for the target application.

Selection Notes

Select this component for designs requiring a compact solution to replace discrete four-component translators. It is suitable for interfacing devices operating at different logic levels such as 1.8 V, 2.5 V, and 3.3 V. Consider its balanced CMOS push-pull outputs and standard CMOS inputs for compatibility with various digital interfaces.

Part Context

This part belongs to the 2N7001T family of single-bit voltage level translators manufactured by Texas Instruments. It serves as a direct replacement for discrete MOSFET-based translation circuits, offering reduced board space and lower power consumption while maintaining high-speed signal integrity.

Replacement Considerations

The 2N7001TDPWR variant offers an X2SON package alternative. Automotive-grade versions include the 2N7001T-Q1 series. Verify pinout compatibility and thermal resistance differences when substituting packages.

FAQ

How does the VCC isolation feature function?

If either VCCA or VCCB input falls below 100 mV, the output port automatically enters a high-impedance state to prevent unintended signal driving.

What is the maximum supported data rate?

The device supports data rates up to 100 Mbps across the full specified supply voltage range.
