Diodes Incorporated 74AUP1G02FZ4-7

Overview

74AUP1G02FZ4-7 from Diodes Incorporated is a single 2-input positive NOR gate in the advanced ultra-low-power (AUP) CMOS logic family, designed for battery-powered portable electronics. It operates across 0.8V–3.6V supply, delivers ±4mA output drive at 3.0V, features IOFF partial power-down protection, and includes Schmitt-trigger inputs with ~250mV hysteresis at VCC = 3.0V for noise-tolerant signal conditioning in space-constrained mobile devices.

For engineers reviewing the 74AUP1G02FZ4-7 datasheet, 74AUP1G02FZ4-7 pinout, 74AUP1G02FZ4-7 application, or 74AUP1G02FZ4-7 equivalent, this device supports low-voltage logic interfacing, level translation between mixed-supply domains, and noise-immune input buffering in ultra-thin consumer electronics where static current < 0.9µA and dynamic CPD = 6.4pF are critical.

Technical Context

The 74AUP1G02FZ4-7 implements standard Boolean NOR logic (Y = A + B) using push-pull CMOS output stages. Its IOFF circuit actively disables outputs during partial power-down to prevent backflow current when VCC = 0V while inputs remain biased.

Schmitt-trigger inputs provide hysteresis (~250mV at 3.0V), enabling robust operation with slow-rising/falling signals common in sensor interfaces and wake-up circuits. The device is fully characterized from –40°C to +125°C and supports CL loads up to 30pF with propagation delays as low as 1.0ns at 3.3V.

FAQ

What is the maximum recommended load capacitance for reliable 74AUP1G02FZ4-7 operation?

The device is fully characterized up to 30pF load capacitance across its operating voltage and temperature ranges. At CL = 30pF and VCC = 3.3V, typical propagation delay remains ≤6.4ns with guaranteed margins. Exceeding 30pF may increase delay unpredictably and reduce noise margin; for heavier loads, consider adding a buffer stage or selecting a higher-drive variant.

Can Pin 5 (NC) be connected to GND or VCC without affecting functionality?

Pin 5 is internally unconnected and must remain floating per Diodes Incorporated's design specification. Tying it to GND or VCC introduces parasitic coupling paths that may degrade ESD performance and increase leakage current. Layout guidelines explicitly require leaving NC pins unbonded and unconnected on PCBs.

Does the 74AUP1G02FZ4-7 support hot insertion or live swapping in powered systems?

No-while IOFF protects against back-current during partial power-down, the device lacks bus-hold or live-insertion circuitry. Applying input signals before VCC stabilization risks latch-up or undefined output states. Always ensure VCC is stable and within spec before asserting inputs in hot-swap scenarios.

How does the Schmitt-trigger input improve reliability in wearable motion sensor interfaces?

The ~250mV hysteresis at 3.0V prevents multiple output transitions caused by slow-rising signals from MEMS accelerometers or gyros with RC filtering. This eliminates false interrupts during low-amplitude vibration events and reduces firmware overhead for software debouncing-critical for extending battery life in always-on motion detection.
