Diodes Incorporated 74AUP2G04FW4-7

Overview

74AUP2G04FW4-7 from Diodes Incorporated is a dual CMOS inverter IC in the Advanced Ultra Low Power (AUP) logic family, designed for battery-powered portable systems requiring operation from 0.8V to 3.6V. It 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 for noise-immune signal conditioning in low-voltage microcontroller I/O buffering.

For engineers reviewing the 74AUP2G04FW4-7 datasheet, 74AUP2G04FW4-7 pinout, 74AUP2G04FW4-7 application, or 74AUP2G04FW4-7 equivalent, this device is selected for ultra-low static current (<0.9µA), fast propagation delay (1.9ns typical at 3.3V/CL=5pF), and robust ESD protection (2kV HBM), especially where space-constrained DFN1010 packaging and rail-to-rail input tolerance are critical.

Technical Context

This dual inverter implements two independent positive-logic Boolean functions (Y = A̅) with push-pull outputs and no internal pull-ups or pull-downs. Its IOFF circuit actively disables outputs during power-down to prevent back-current flow, enabling safe hot-insertion in multi-rail systems.

Schmitt-trigger inputs provide defined switching thresholds across the full 0.8V–3.6V supply range, with VIH/VIL thresholds scaling dynamically (e.g., VIH = 0.80×VCC at 0.8V–1.65V), ensuring reliable operation despite slow-rising signals or noisy PCB traces in handheld and wearable electronics.

FAQ

What is the maximum recommended operating temperature for 74AUP2G04FW4-7?

The device is fully specified from –40°C to +125°C ambient temperature, with junction temperature rated up to +150°C. At maximum ambient, derating applies: total power dissipation must remain below 120mW to maintain TJ ≤ 150°C in still air with typical PCB copper area.

Does 74AUP2G04FW4-7 require external pull-up or pull-down resistors on unused inputs?

Yes. Per datasheet Note 8, unused inputs must be tied to either VCC or GND to prevent floating states that increase ICC and cause unpredictable output behavior. The Schmitt-trigger inputs do not eliminate this requirement-they only improve noise margin on actively driven inputs.

Can 74AUP2G04FW4-7 drive a 50pF load at 10MHz without signal degradation?

Yes. With CL = 50pF and f = 10MHz, dynamic power consumption remains under 15µW (CPD ≈ 6pF × (3.3V)² × 10MHz), well within its 120mW thermal limit. Propagation delay increases to ~6.5ns (vs. 1.9ns at 5pF), but output rise/fall times stay <3ns, preserving signal integrity.

Is the X2-DFN1010-6 package compatible with standard reflow profiles for lead-free soldering?

Yes. The package supports IPC/JEDEC J-STD-020D peak reflow temperatures up to 260°C for 30 seconds. Its 0.35mm pad pitch and wettable flanks ensure reliable solder joint formation and AOI detectability using standard Type 3 solder paste and stencil apertures.
