SN74AUP1T50DCKR

Buffers, Drivers, Receivers, Transceivers Overview

The SN74AUP1T50DCKR is a single-supply voltage translator manufactured by Texas Instruments. It operates with input voltages ranging from 1.8 V to 3.3 V and provides outputs compatible with 3.3-V CMOS levels. The device features Schmitt-trigger inputs for noise immunity and functions as a non-inverting buffer. It is housed in a compact SC-70-5 package, designed for low-power applications requiring level shifting between different voltage domains.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Single-supply operation supporting 1.8 V, 2.5 V, and 3.3 V input levels
• Schmitt-trigger inputs provide enhanced noise filtering capabilities
• Output levels adapt to the supply voltage (VCCA) up to 3.3 V CMOS compatibility

Buffers, Drivers, Receivers, Transceivers Applications

• Level translation between 1.8 V and 3.3 V logic domains
• Bidirectional data buffering in mixed-voltage systems
• Interface circuits connecting low-voltage microcontrollers to higher-voltage peripherals

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'DCKR' corresponds to the SC-70-5 tape-and-reel packaging configuration. Confirm that the required voltage translation direction matches the application's VCCA and VCCB connections. Ensure the design accounts for the Schmitt-trigger input characteristics when interfacing with slow-rise-time signals.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when bidirectional level shifting is required between 1.8–3.3 V inputs and 3.3 V outputs. The Schmitt-trigger feature makes it suitable for noisy environments or signals with poor rise/fall times. Compare against standard AUC buffers if unbuffered transmission is sufficient, noting the added noise immunity of the AUP series.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the SN74AUP1T family of single-supply voltage translators. Unlike the SN74AUC1G series which offers fixed logic gates, the AUP1T series focuses on bidirectional level translation. The DCKR suffix denotes the SC-70-5 surface-mount package variant within the broader AUP product line.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

SN74AUP1T50DCKT is the reel-pack equivalent of the DCKR tray/tape variant. For unidirectional translation without Schmitt triggers, consider SN74AUC1G08DCKR, though it lacks bidirectional capability and Schmitt input protection.
