Overview
The SN74AUP1G14DCKR is a single-channel inverting Schmitt trigger integrated circuit manufactured by Texas Instruments. It operates within a supply voltage range of 0.8 V to 3.6 V and supports a maximum high-level output current of -4 mA and a low-level output current of 4 mA. The device functions reliably across an operating temperature range from -40 °C to +85 °C. Propagation delay varies between 6.2 ns and 20.5 ns depending on load conditions, with specific measurements including 17.1 ns, 12.3 ns, 10.3 ns, and 7.4 ns under various test configurations.
Feature Summary
- Integrates Schmitt trigger input functionality to provide noise immunity and signal conditioning for slow-rising waveforms.
- Supports ultra-low-power operation through the AUP logic series architecture.
- Delivers standardized digital inversion within a compact surface-mount package.
Applications
- Signal conditioning for noisy digital environments
- Waveform shaping of slow-rise time signals
- Pulse generation circuits
Procurement Notes
Verify the complete part number against official Texas Instruments documentation to ensure correct suffix alignment. Confirm that the DCKR designation corresponds to the SC-70-5 package and reel packaging specifications. Cross-reference RoHS compliance status and moisture sensitivity levels prior to integration into production workflows.
Selection Notes
Select this component when designing systems requiring Schmitt trigger inputs combined with low-voltage compatibility. The AUP series offers superior power efficiency compared to standard CMOS families. Ensure the application voltage remains within the 0.8 V to 3.6 V operational window to maintain specified electrical characteristics.
Part Context
This device belongs to the SN74AUP1Gxx family of single-gate logic ICs. It shares the SC-70-5 (SOT-353) footprint with other variants such as the SN74AUP1G00DCKR and SN74AUP1T04DCKR. The family emphasizes miniaturization and energy efficiency for portable electronics.
FAQ
What is the primary function of the Schmitt trigger input?
It converts slowly changing analog-like signals into clean, sharp digital transitions while rejecting noise near the switching threshold.
Does this component include internal pull-up or pull-down resistors?
No, the datasheet specifies it as a standalone inverter without integrated biasing resistors.
