Overview
The SN74AUP1T02DCKR is a single-channel, two-input positive NOR gate from Texas Instruments' AUP logic family. It operates on a single power supply ranging from 0.8V to 3.6V and features Schmitt-trigger inputs for noise filtering. The device accepts 1.8V LVCMOS signals when powered by 3.3V or 2.5V supplies. It provides a maximum propagation delay of 4.4ns at 3.3V with a 30pF load and supports output currents of ±4mA. Operating temperatures range from -40°C to +85°C.
Feature Summary
- Schmitt-trigger inputs provide enhanced noise immunity and signal conditioning
- LVCMOS signal compatibility ensures interoperability with standard logic levels
- Low-power design extends battery life in portable applications
- High-speed operation maintains signal integrity across the voltage range
Applications
- Signal conditioning for noisy digital environments
- Level translation between different logic families
- Battery-powered portable electronic devices
- General-purpose logic processing in low-voltage systems
Procurement Notes
Verify the specific suffix 'DCKR' corresponds to the SC-70-5 package and tape-and-reel quantity. Confirm RoHS compliance status and moisture sensitivity level (MSL) ratings prior to assembly. Ensure the ordering part number matches the exact logic function and pinout requirements for the target PCB layout.
Selection Notes
Select this component when Schmitt-trigger hysteresis is required for input stability. The wide operating voltage range allows flexibility in system power design. Consider the SC-70-5 footprint constraints and thermal characteristics during placement. Verify that the propagation delay meets the timing requirements of the specific application circuit.
Part Context
This device belongs to the SN74AUP series, designed for ultra-low power consumption while maintaining high speed. The AUP technology targets applications requiring extended battery life without sacrificing performance. It serves as a compact solution for basic logic functions in space-constrained designs.
Replacement Considerations
Check for direct substitutes within the same AUP family with identical pinouts. Verify functional equivalence regarding Schmitt-trigger thresholds and output drive capabilities before substitution.
