Overview
The SN74AUC1G14MDBVREP is a single Schmitt-trigger inverter from the Texas Instruments 74AUC series, housed in a SOT-23 (DBV) package. It operates within a supply voltage range of 0.8 V to 2.7 V and supports an extended temperature range of -55°C to 125°C. The device features low power consumption with a maximum static current of 10 µA and provides output drive currents up to ±9 mA. Propagation delay is specified at a maximum of 3 ns at 2.5 V with a 30 pF load. It includes Ioff circuitry for partial-power-down support and meets enhanced latch-up performance standards.
Feature Summary
- Schmitt-trigger action provides distinct input threshold levels for positive-going and negative-going signals to ensure noise immunity.
- Ioff circuitry disables outputs to prevent damaging current backflow during partial-power-down mode operation.
- Enhanced product reliability features include controlled baseline manufacturing and qualification pedigree supporting extended temperature ranges.
Applications
- Mixed-mode signal operation supporting 3.6-V I/O tolerance
- Partial-power-down applications requiring output isolation
- Sub-1-V logic circuits optimized for low-voltage operation
Procurement Notes
Verify the specific ordering suffix MDBVREP corresponds to the SOT-23 package and lead finish requirements. Confirm that the Enhanced Product (EP) designation aligns with project reliability standards, as these components follow controlled baseline manufacturing protocols. Ensure compatibility with the required assembly site and fabrication site specifications defined in the datasheet.
Selection Notes
Select this component when a single inverter with hysteresis is required for sub-1-V or 1.8-V logic systems. The device is suitable for designs needing 3.6-V I/O tolerance despite lower supply voltages. Consider the SOT-23 footprint constraints and the need for Schmitt-trigger inputs to clean noisy signals in low-voltage environments.
Part Context
This part belongs to the SN74AUC1G14-EP family, representing an enhanced product version of the standard SN74AUC1G14. It utilizes Texas Instruments NanoStar technology within the DBV package. The EP designation indicates adherence to stricter quality and reliability controls compared to standard catalog versions.
Replacement Considerations
The catalog version SN74AUC1G14 serves as a functional equivalent but lacks the Enhanced Product (EP) qualification pedigree. Verify if the controlled baseline manufacturing and specific reliability testing associated with the EP variant are mandatory for the application before substituting.
