Diodes Incorporated 74AUP2G34FZ4-7

Overview

74AUP2G34FZ4-7 from Diodes Incorporated is a dual non-inverting buffer IC in the Advanced Ultra Low Power (AUP) CMOS logic family, designed for signal conditioning and level translation in 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-immune interfacing in handheld computing and mobile peripherals.

For engineers reviewing the 74AUP2G34FZ4-7 datasheet, 74AUP2G34FZ4-7 pinout, 74AUP2G34FZ4-7 application, or 74AUP2G34FZ4-7 equivalent, this device is selected for ultra-low static current (<0.9µA), fast propagation delay (as low as 1.4ns at 3.3V/CL=5pF), robust ESD protection (2kV HBM), and compatibility with mixed-voltage I/O domains in space-constrained designs.

Technical Context

This dual buffer implements two independent positive-logic A → Y functions with standard push-pull outputs and no internal inversion. Its IOFF circuit actively disables outputs during power-down to prevent backflow current, enabling safe hot-insertion and partial system shutdown.

Schmitt-trigger inputs provide defined switching thresholds and immunity to slow-rising signals-critical for interfacing with mechanical switches, sensors, or legacy logic. The device supports full rail-to-rail input voltage range (0–VCC) and maintains guaranteed output swing within 0.1V of rails under load.

FAQ

Does 74AUP2G34FZ4-7 support true 0.8V operation with guaranteed timing?

Yes. The datasheet specifies tPD = 14.9ns at 0.8V (CL = 5pF), VIH/VIL thresholds scale with VCC, and ICC remains below 0.9µA - confirming full functionality down to 0.8V across commercial temperature range. No derating or external biasing is required.

Can unused inputs be left floating?

No. Per datasheet Note 8, unused inputs must be tied to VCC or GND to prevent increased ICC, oscillation, or ESD susceptibility. Floating inputs cause undefined logic states and may elevate static current by up to 75µA due to internal gate leakage paths.

Is the X2-DFN1410-6 package thermally enhanced?

The package has no integrated thermal pad, but its 1.4mm × 1.0mm footprint and 0.4mm height allow efficient heat dissipation through copper pour and solder reflow. Thermal resistance θJA is 210°C/W (typical), sufficient for ≤1mW total power dissipation in ambient air.

How does IOFF behave when VCC = 0V but inputs are pulled to 3.3V?

IOFF limits reverse current to ±0.2µA max (TA = +25°C), preventing damage to upstream drivers. This allows safe "hot insertion" into live backplanes and eliminates need for external blocking diodes in partial-power-down architectures.
