SN74AUP1T98DCKR

Translators, Level Shifters Overview

The SN74AUP1T98DCKR is a single-channel, unidirectional voltage level translator from the Texas Instruments SN74AUP1T series. It operates with VCCA ranging from 1.8 V to 2.7 V and VCCB from 2.3 V to 3.6 V, enabling translation between low-voltage and standard logic domains. The device features configurable gate logic functions, allowing it to act as an AND, NAND, OR, NOR, or buffer depending on control pin states. Packaged in a compact SC-70-5 (SOT-353) surface-mount footprint, it supports operation across an industrial temperature range of -40°C to +85°C.

Translators, Level Shifters Feature Summary

• Configurable multi-function logic capability allows implementation of various boolean operations within a single package
• Unidirectional data flow ensures signal integrity during voltage translation between dissimilar power domains
• Dual-supply architecture isolates A and B ports for independent voltage domain operation

Translators, Level Shifters Applications

• Interfacing low-voltage microcontrollers with higher-voltage peripheral devices
• Bidirectional bus buffering where directionality is managed by external circuitry
• Portable electronics requiring minimal board space for logic translation

Translators, Level Shifters Procurement Notes

Verify the specific suffix DCKR corresponds to the SC-70-5 package variant when sourcing. Confirm that the configurable control pins are properly terminated in your design to ensure the intended logic function. Check for recent Product Change Notifications regarding assembly sites or material composition updates prior to finalizing procurement orders.

Translators, Level Shifters Selection Notes

Select this component when a single IC must replace multiple discrete gates to save space. Ensure the target application requires unidirectional translation only, as bidirectional variants exist. Verify that the voltage difference between the 1.8V–2.7V and 2.3V–3.6V domains falls within the device's specified operating limits for reliable switching.

Translators, Level Shifters Part Context

This part belongs to the SN74AUP1T family of ultra-low-power level translators. Unlike fixed-function gates, these devices offer flexible logic implementation through pin configuration. The DCKR suffix specifically denotes the SC-70-5 package, distinguishing it from other form factors like DSBGA or DBVT found in the same logical family.

Translators, Level Shifters Replacement Considerations

SN74AUP1T98DBVR is a direct functional substitute in a different SOT-23-6 package. SN74AUP1T98DSFR offers the same functionality in an X2SON package. Verify pin compatibility and thermal performance when swapping between these package types.
