Overview
The SN74AUP1G32DCKR is a single-channel, two-input positive-OR gate from the Texas Instruments SN74AUP1Gxx series. It operates within a supply voltage range of 0.8 V to 3.6 V and features Schmitt-trigger inputs for noise immunity. The device provides 4 mA high-level and low-level output drive currents. Maximum propagation delay is specified at 6.4 ns when operating at 3.3 V with a 30 pF load. It is housed in a SC-70-5 surface-mount package and supports an industrial temperature range from -40°C to +85°C.
Feature Summary
- Single-channel OR logic function with two inputs
- Schmitt-trigger input configuration for signal conditioning
- Low quiescent current consumption of 500 nA maximum
- Compatible with low-voltage power supplies down to 0.8 V
Applications
- Signal routing and selection circuits
- Logic level translation interfaces
- Battery-powered portable devices
- Consumer electronics control logic
Procurement Notes
Verify the specific suffix DCKR corresponds to the SC-70-5 package variant during procurement. Confirm RoHS compliance status as indicated in official documentation. Ensure the ordering part number matches the required tape-and-reel packaging format. Cross-reference the manufacturer's latest datasheet for any potential design changes or pinout updates before finalizing component selection.
Selection Notes
Select this component when a compact, low-power OR gate is required for sub-1V to 3.6V systems. The Schmitt trigger feature makes it suitable for noisy environments or slow-rising signals. Compare against standard AUP variants if higher speed or different package options are needed. Verify that the 4 mA drive capability meets the load requirements of the downstream circuitry.
Part Context
This device belongs to the SN74AUP1Gxx family of ultra-low-power single-gate logic ICs. These components are designed for space-constrained applications requiring minimal power consumption. The AUP series offers performance comparable to older technologies while supporting lower supply voltages. The SC-70-5 package allows for high-density PCB layouts in modern electronic designs.
