Overview
The SN74AUP1T32DCKR is a single-channel Schmitt-trigger OR gate from the Texas Instruments 74AUP series. It operates within a supply voltage range of 2.3V to 3.6V and features two inputs with one output in an SC-70-5 package. The device exhibits a maximum static current of 500 nA and provides output drive currents of 4mA for both high and low states. At 3.3V with a 30pF load, the maximum propagation delay is 4.4ns. It supports logic levels between 0.35V–0.5V (low) and 1.1V–1.19V (high), functioning reliably across temperatures from -40°C to 85°C.
Feature Summary
- Integrates Schmitt trigger input characteristics to enhance noise immunity and signal conditioning.
- Provides positive OR logic functionality within a single-channel configuration.
- Supports operation across a wide temperature range suitable for industrial applications.
Applications
- Signal processing circuits requiring noise filtering
- Battery-powered portable devices due to low power consumption
- Consumer electronics utilizing low-voltage logic interfaces
Procurement Notes
Verify the specific ordering suffix against official documentation to confirm packaging type and reel specifications. Ensure compatibility with RoHS3 standards and check for any recent Product Change Notifications regarding assembly sites or marking updates before finalizing procurement orders.
Selection Notes
Select this component when Schmitt trigger hysteresis is required for OR logic operations in low-voltage environments. Compare against standard AUP gates if noise immunity is not critical, or consider LVC series if higher drive current or wider voltage ranges are necessary for the target application design.
Part Context
This part belongs to the SN74AUP family of ultra-low-power CMOS logic devices. It shares functional similarities with other single-gate variants like the SN74AUP1G32 but includes Schmitt trigger inputs for improved signal integrity. The DCKR suffix indicates the SC-70-5 surface-mount package configuration used for compact board layouts.
Replacement Considerations
SN74AUP1T32DCKRG4 is a verified equivalent variant within the same product line offering identical electrical characteristics and pinout compatibility.
