SN74AUP1T87DCKR

Overview

The SN74AUP1T87DCKR is a single-channel voltage level translator from Texas Instruments, designed for low-power applications. It operates with input voltages of 1.8 V, 2.5 V, or 3.3 V and provides a 3.3 V CMOS output. The device features an XNOR logic function within a 5-pin SC-70 surface-mount package. It supports bidirectional data transfer between different voltage domains while maintaining low power consumption.

Feature Summary

• Supports multiple input voltage levels including 1.8 V, 2.5 V, and 3.3 V
• Provides 3.3 V CMOS compatible output levels
• Implements XNOR logic functionality for signal translation
• Utilizes compact SC-70 packaging for space-constrained designs

Applications

• Bidirectional voltage translation between 1.8 V and 3.3 V systems
• Interface bridging in mixed-voltage digital circuits
• Low-power portable electronic devices requiring level shifting

Procurement Notes

Verify the specific suffix DCKR corresponds to the SC-70 tape-and-reel packaging configuration. Confirm that the XNOR logic function aligns with the intended circuit design requirements rather than standard buffer or inverter functions. Ensure compatibility with the target operating temperature range and supply voltage specifications before integration.

Selection Notes

Select this component when bidirectional translation between lower voltage inputs (1.8 V/2.5 V) and 3.3 V outputs is required alongside XNOR logic processing. Consider the SC-70 package size for PCB layout constraints. Evaluate power consumption benefits compared to standard logic families if energy efficiency is a primary design driver.

Part Context

This part belongs to the SN74AUP1T series of voltage translators from Texas Instruments. These devices are engineered for low-power operation and facilitate communication between components operating at different voltage levels. The AUP series typically offers improved performance over standard 74HC logic in terms of speed and power efficiency.

Replacement Considerations

Check for other SN74AUP1T variants with different logic functions if XNOR is not strictly required. Verify pinout compatibility with alternative SC-70 level shifters from other manufacturers if supply chain adjustments are necessary.
