SN74AUP1T158DCKR

Overview

The SN74AUP1T158DCKR is a low-power, single 2-input Schmitt-trigger buffer multiplexer manufactured by Texas Instruments. It operates within a supply voltage range of 2.3 V to 3.6 V and features inputs compatible with 1.8 V, 2.5 V, or 3.3 V logic levels while providing a 3.3 V CMOS output. The device is housed in an SC-70-6 package and exhibits a propagation delay of 5.1 ns. It functions as an inverting logic element suitable for voltage level translation applications across the specified temperature range.

Feature Summary

• Integrates Schmitt-trigger input characteristics to enhance noise immunity during signal transitions.
• Supports configurable voltage level translation between 1.8 V, 2.5 V, and 3.3 V input domains.
• Provides a single 2:1 multiplexer function with inverted logic output behavior.

Applications

• Voltage level translation between mixed-voltage digital systems
• Signal buffering in portable battery-powered devices
• Data routing in low-power consumer electronics

Procurement Notes

Verify the specific suffix 'DCKR' corresponds to the SC-70-6 package and tape-and-reel shipping configuration. Confirm that the component meets RoHS compliance requirements as indicated by the manufacturer's standard specifications. Ensure the operating environment remains within the -40°C to +85°C temperature range to maintain guaranteed electrical performance parameters.

Selection Notes

Select this component when a compact, single-channel multiplexer with Schmitt-trigger inputs is required for low-power applications. It is appropriate for designs needing to interface different voltage domains without external level-shifting circuitry. Consider the SC-70-6 footprint constraints and the specific inverting logic requirement before finalizing the schematic design.

Part Context

This part belongs to the SN74AUP1T series, which focuses on ultra-low power consumption and high-speed operation in small packages. The AUP family is designed for modern portable electronics where power efficiency and space savings are critical. The SN74AUP1T158 specifically addresses the need for buffered, translated signals in minimal form factors.

Replacement Considerations
