SN74AUP1T04DCKR

Overview

The SN74AUP1T04DCKR is a single-channel inverter from the Texas Instruments 74AUP logic family, housed in a surface-mount SC-70-5 package. It operates within a supply voltage range of 2.3V to 3.6V and supports a wide operating temperature range from -40°C to +85°C. The device features Schmitt-trigger inputs for noise immunity and provides output drive currents of 4mA at both high and low states. Maximum propagation delay is specified as 4.4ns at 3.3V with a 30pF load, while maximum static current consumption is limited to 500nA.

Feature Summary

• Schmitt trigger input action ensures clean signal transitions and improved noise immunity
• Ultra-low power consumption design suitable for battery-operated applications
• Wide supply voltage operation supporting multiple logic levels
• High-speed performance with nanosecond-level propagation delays

Applications

• Digital signal conditioning and waveform shaping
• Logic level translation between different voltage domains
• Noise filtering in digital communication interfaces
• Signal inversion in portable electronic devices

Procurement Notes

Verify the specific ordering suffix DCKR corresponds to the SC-70-5 package configuration required for your PCB layout. Confirm that the 2.3V minimum supply voltage aligns with your system's power rails, as this differs from standard 1.8V-compatible logic families. Ensure thermal management meets the -40°C to +85°C industrial grade requirements for your intended environment.

Selection Notes

Select this component when Schmitt trigger hysteresis is required for noisy digital signals within the AUP voltage range. It serves as a direct functional replacement for other single inverters in the 74AUP series sharing the same pinout. Consider the 4mA drive capability against your load requirements and verify compatibility with your target clock frequencies given the 4.4ns delay specification.

Part Context

This part belongs to the SN74AUP1Txx series of ultra-low-power single-gate logic devices. The 'T' designation indicates the inclusion of Schmitt trigger inputs, distinguishing it from the standard SN74AUP1G04 which lacks hysteresis. The DCKR suffix identifies the specific SC-70-5 tape-and-reel packaging variant manufactured by Texas Instruments.

Replacement Considerations

SN74AUP1G04DCKR offers identical electrical characteristics but without Schmitt trigger inputs. SN74AUP1G14DCKR provides the same Schmitt trigger functionality in a similar package. Verify pinout compatibility before substituting with other single-inverter variants in the AUP family.
