Texas Instruments SN74AUP1G32DPWR

Overview

SN74AUP1G32DPWR from Texas Instruments is a low-power single 2-input positive-OR gate in an ultra-small X2SON-5 (DPW) package (0.8 mm × 0.8 mm, 0.5-mm pitch), operating from 0.8 V to 3.6 V supply, delivering 4.6 ns max propagation delay at 3.3 V, 0.9 µA max ICC, and 4.3 pF typical Cpd - deployed in battery-powered portable electronics requiring minimal board space and ultra-low static/dynamic power.

For engineers reviewing the SN74AUP1G32DPWR datasheet, SN74AUP1G32DPWR pinout, SN74AUP1G32DPWR application, or SN74AUP1G32DPWR equivalent, key selection criteria include its Ioff support for live insertion and partial power-down, input hysteresis (250 mV typ) for noise immunity with slow transitions, 3.6-V I/O tolerance enabling mixed-voltage interfacing, and verified performance across –40°C to 85°C industrial temperature range.

Technical Context

This device implements the Boolean function Y = A + B in positive logic using advanced CMOS AUP (Advanced Ultra-Low-Power) process technology. It features rail-to-rail output swing, balanced drive strength, and built-in input hysteresis to suppress switching noise on slow or noisy inputs.

The SN74AUP1G32DPWR operates across a wide VCC range (0.8 V–3.6 V) while maintaining consistent timing and logic thresholds - enabling direct interface between sub-1V microcontrollers and 3.3-V peripherals without external level shifters. Its Ioff specification ensures isolation when VCC = 0 V, preventing back-drive and supporting hot-plug scenarios.

FAQ

What is the maximum operating temperature for SN74AUP1G32DPWR?

The SN74AUP1G32DPWR is rated for continuous operation from –40°C to +85°C ambient temperature, validated per JEDEC JESD22-A104 thermal cycling and JESD22-A108 high-temperature operating life testing. This range covers industrial, medical, and consumer applications including blood pressure monitors and wireless headsets exposed to body heat and environmental variation. The DPW package's RθJA of 492.1°C/W ensures safe junction temperatures under typical 1-mA load conditions.

Does SN74AUP1G32DPWR support partial power-down mode?

Yes, SN74AUP1G32DPWR supports partial power-down mode via its Ioff specification: when VCC = 0 V, all inputs and outputs are high-impedance and leakage current is limited to 0.6 µA max, preventing back-driving of powered circuitry. This feature is explicitly tested per JESD78 Class II latch-up standards and enables safe hot-insertion in modular field transmitters and USB-C accessory docks where subsystems power up asynchronously.

Can SN74AUP1G32DPWR interface between 1.2-V and 3.3-V logic domains?

Yes, SN74AUP1G32DPWR can safely interface 1.2-V and 3.3-V logic domains: its inputs accept voltages up to 3.6 V independent of VCC, and its outputs swing rail-to-rail within the VCC range (0.8–3.6 V). When powered at 1.2 V, it correctly interprets 3.3-V inputs as logic HIGH (VIH = 0.65 × VCC = 0.78 V), and its 3.6-V-tolerant outputs prevent damage when driving 3.3-V receivers - confirmed in TI's Application Report SCBA004.

What is the recommended bypass capacitor for SN74AUP1G32DPWR?

A 0.1 µF X7R ceramic capacitor placed ≤1 mm from the VCC pin (Pin 5) and GND (Pin 3) is mandatory for stable operation of SN74AUP1G32DPWR. This value is specified in TI's Power Supply Recommendations section (Section 10) and validated across all VCC operating points (0.8–3.6 V). For systems with shared power rails, paralleling a 1 µF capacitor improves low-frequency noise rejection without compromising high-frequency transient response.

Is SN74AUP1G32DPWR pin-compatible with other 5-pin logic gates in X2SON packages?

No - SN74AUP1G32DPWR has a fixed pinout (A-B-GND-Y-VCC) defined in Figure 5-7 of the datasheet, and TI does not guarantee pin compatibility across different logic functions (e.g., AND, NAND, inverters) even within the same X2SON-5 package. Substituting with another function requires verification of both pin mapping and electrical behavior; for example, SN74AUP1G08 (AND gate) uses identical pin numbering but different internal logic, making direct replacement invalid without schematic review.
