Overview

The SN74AUP1G08DCKR is a single 2-input positive-AND gate from Texas Instruments Advanced Ultra-Low-Power (AUP) logic family. Designed for battery-operated and power-sensitive applications, it operates across a wide voltage range of 0.8V to 3.6V with extremely low static and dynamic power consumption. The device includes Ioff circuitry for partial-power-down modes, preventing damaging backflow current when the system is powered down.

Why Choose This Part

This AND gate offers an industry-leading quiescent current of only 0.9 microamps and a low propagation delay of 4.3ns at 3.3V. Its Schmitt-trigger inputs provide 250mV of typical hysteresis, ensuring clean switching even with slow or noisy input signals. The ultra-compact SC-70-5 package saves significant board real estate in high-density designs.

Applications

Handheld Medical Devices
Ideal for portable glucose meters and pulse oximeters where ultra-low power consumption extends battery life.
Mixed-Voltage Systems
Utilized as a logic buffer or gate in systems with 1.8V, 2.5V, and 3.3V rails due to its 3.6V I/O tolerance.
Smartphone and Tablet Logic
Commonly used for simple glue logic in mobile devices where PCB space and power efficiency are critical.
Live-Insertion Modules
The Ioff feature makes it suitable for hot-swappable line cards and modules by protecting the circuitry during partial power-down.

Getting Started

To evaluate this component, designers typically use generic SC-70 breakout boards for breadboarding or prototype SMT adapters. Ensure that VCC is decoupled with a 0.1 microfarad ceramic capacitor placed as close to the pin as possible to maintain signal integrity at low voltages.
