Diodes Incorporated 74AUP2G08RA3-7

Overview

74AUP2G08RA3-7 from Diodes Incorporated is a dual 2-input AND gate in the Advanced Ultra Low Power (AUP) CMOS logic family, 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 uses Schmitt-trigger inputs with ~250mV hysteresis at VCC = 3.0V for noise immunity in low-voltage signal routing.

For engineers reviewing the 74AUP2G08RA3-7 datasheet, 74AUP2G08RA3-7 pinout, 74AUP2G08RA3-7 application, or 74AUP2G08RA3-7 equivalent, key selection criteria include ultra-low ICC (<0.9µA), wide VCC range compatibility, IOFF-enabled system-level power sequencing, and DFN1210-8 footprint constraints in space-constrained mobile PCB layouts.

Technical Context

This device implements two independent positive-logic AND functions (Y = A • B) using push-pull CMOS outputs. Its IOFF circuit actively disables outputs during power-down to prevent back-current flow between powered and unpowered rails-critical for mixed-voltage domain interconnects in modern portable SoC subsystems.

Schmitt-trigger inputs provide defined switching thresholds and hysteresis (~250mV at 3.0V), enabling robust operation with slow-rising or noisy signals common in I²C pull-up networks, reset line conditioning, and wake-up logic interfaces where edge integrity is compromised by RC delays or EMI.

FAQ

Can 74AUP2G08RA3-7 operate reliably at 0.85V supply?

Yes - the device is fully characterized down to 0.8V, with guaranteed tPD ≤12.9ns (CL=5pF) and VIH/VIL thresholds scaling correctly at 0.85V. Input hysteresis remains functional, and IOFF leakage stays below ±0.6µA across –40°C to +125°C, making it suitable for energy-harvesting systems with dynamically varying rail voltages.

Does the X2-DFN1210-8 package require solder paste stencil adjustments?

Yes - Diodes' AP02001 recommends a 0.12mm-thick stencil with 0.11mm × 0.27mm apertures for the eight perimeter pads and a 0.25mm × 0.25mm aperture for the center thermal pad. Underfill is not required, but reflow profile must achieve peak temperature ≥235°C for void-free thermal pad wetting per JEDEC J-STD-020.

How does IOFF behave when VCC = 0V but inputs are pulled to 1.8V?

With VCC = 0V, the IOFF circuit disables both outputs, limiting leakage to ±0.6µA maximum even if 1.8V is applied to any input or output pin. This prevents current flow from the 1.8V domain into the grounded VCC rail - verified per JESD78 latch-up testing and absolute maximum ratings (VI = –0.5V to VCC + 0.5V).

Is the Schmitt trigger threshold adjustable via external bias?

No - hysteresis is fixed by internal transistor sizing and cannot be adjusted. At VCC = 3.0V, VIH ≈ 2.0V and VIL ≈ 0.9V, yielding ~250mV hysteresis. External resistor dividers on inputs are not recommended, as they degrade noise margin and violate the specified VI range (0 to VCC); use only direct CMOS-level signals.
