Diodes Incorporated 74AUP1G08FS3-7

Overview

74AUP1G08FS3-7 from Diodes Incorporated is a single 2-input positive AND gate in ultra-low-power CMOS logic, designed for battery-powered portable systems. It operates across 0.8V–3.6V supply, delivers ±4mA output drive at 3.0V, features IOFF partial power-down protection, and integrates Schmitt-trigger inputs with ~250mV hysteresis at VCC = 3.0V - enabling robust signal conditioning in noise-prone mobile interfaces.

For engineers reviewing the 74AUP1G08FS3-7 datasheet, 74AUP1G08FS3-7 pinout, 74AUP1G08FS3-7 application, or 74AUP1G08FS3-7 equivalent, this device is selected for low-voltage logic level translation, enable/control gating in wearables and IoT sensors, and power-aware signal routing where static current <0.9µA and propagation delay ≤2.2ns (at 3.3V, CL=5pF) are critical.

Technical Context

This AND gate implements standard Boolean Y = A • B using advanced ultra-low-power (AUP) CMOS process technology. Its IOFF circuit actively disables outputs during partial power-down, blocking reverse current flow when VCC = 0V while inputs remain biased - essential for mixed-supply domain isolation in modern portable SoC subsystems.

Schmitt-trigger inputs provide input hysteresis (~250mV at 3.0V), allowing reliable operation with slow-rising/falling signals from mechanical switches or RC networks. The device is fully characterized from –40°C to +125°C and supports 0.8V minimum VCC - enabling direct interfacing with sub-1V I/O domains in next-gen microcontrollers.

FAQ

What is the maximum recommended load capacitance for stable operation?

The device is characterized up to 30pF load capacitance with guaranteed timing performance. At CL = 30pF and VCC = 3.3V, typical propagation delay is 4.2ns. For designs exceeding 30pF, derate timing margins by ≥20% and verify signal integrity via board-level testing due to increased slew rate degradation.

Can Pin 6 (NC) be grounded or left floating?

Pin 6 is internally unconnected and must be left floating per Diodes' design guidelines. Grounding it may cause unintended parasitic coupling or violate package thermal performance assumptions. No electrical or reliability benefit results from connecting NC pins.

Does the IOFF feature work when VCC = 0V but inputs are pulled to 3.3V?

Yes - IOFF activates when VCC = 0V, limiting input-to-output leakage to ≤0.6µA even with inputs at 3.3V. This prevents back-driving powered-down sections and complies with JEDEC JESD78 latch-up immunity requirements under partial power-down conditions.

Is the X2-DFN0808-4 package compatible with standard reflow profiles?

Yes - the X2-DFN0808-4 package is qualified for IPC/JEDEC J-STD-020D moisture sensitivity level 1 and supports peak reflow temperatures up to 260°C. Use standard lead-free profile with ramp rates ≤3°C/s and dwell time at peak temperature ≤60 seconds.
