2N7001TQDCKRQ1

Overview

The Texas Instruments 2N7001TQDCKRQ1 is an automotive-qualified, single-bit dual-supply buffered voltage signal converter housed in a five-pin SC-70 (DCK) package. It supports bidirectional supply voltages ranging from 1.65 V to 3.6 V on both VCCA and VCCB rails. The device facilitates unidirectional logic level translation with propagation delays between 10 ns and 20 ns depending on supply conditions. It features a maximum quiescent current of 14 µA at 125°C and operates within a temperature range of –40°C to +125°C.

Feature Summary

• Supports up and down translation across 1.65 V to 3.6 V using two separate configurable power-supply rails
• Includes VCC isolation feature that forces the output to high-impedance if either supply drops below 100 mV
• Enables partial-power-down mode operation through Ioff protection circuitry to prevent excessive current draw
• Provides integrated ESD protection exceeding JEDEC standards for human body model and charged-device model

Applications

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

Procurement Notes

Verify the AEC-Q100 qualification status and specific ordering suffixes when sourcing this component. Confirm that the SC-70 package dimensions align with your PCB layout constraints. Ensure design parameters respect the absolute maximum ratings for input and output voltages to maintain reliability under automotive operating conditions.

Selection Notes

Select this component for designs requiring a compact solution to replace discrete FET-based translators. It offers minimized implementation size and lower power consumption compared to multi-component solutions. Consider its balanced CMOS push-pull outputs for driving larger currents while maintaining fast edge rates into light loads.

Part Context

This device belongs to the 2N7001T family of voltage signal converters designed for automotive applications. It serves as a direct replacement for discrete translation implementations, providing a single small footprint alternative. The Q1 suffix indicates automotive qualification, ensuring suitability for demanding environments requiring extended temperature ranges and robust performance.

Replacement Considerations

The catalog version 2N7001T is a qualified non-automotive alternative within the same product family.
