Diodes Incorporated 74AUP2G17FW3-7

Overview

74AUP2G17FW3-7 from Diodes Incorporated is a dual Schmitt trigger buffer IC in X2-DFN0910-6 package, operating from 0.8V to 3.6V supply, delivering ±4mA output drive at 3.0V with ICC < 0.9µA static current, designed for noise-immune signal conditioning in ultra-low-power portable systems.

For engineers reviewing the 74AUP2G17FW3-7 datasheet, 74AUP2G17FW3-7 pinout, 74AUP2G17FW3-7 application, or 74AUP2G17FW3-7 equivalent, key selection criteria include Schmitt input hysteresis (ΔVT = 0.79–1.31V at 3.0V), IOFF-enabled partial power-down capability, and 0.9mm × 1.0mm DFN footprint for space-constrained battery-powered designs.

Technical Context

This device implements two independent non-inverting Schmitt trigger buffers with push-pull outputs and IOFF circuitry that disables outputs during power-down to prevent backflow current. Each channel features asymmetric input thresholds (VT+ = 1.88–2.29V, VT− = 0.88–1.24V at VCC = 3.0V) enabling robust noise rejection on slow-rising/falling signals.

It supports wide-voltage operation (0.8V–3.6V), delivers propagation delays as low as 1.1ns (typ.) at 3.3V/CL = 5pF, and maintains latch-up immunity >100mA per JESD78 Class I - all within a 0.9mm × 1.0mm × 0.35mm leadless DFN package with 0.35mm pad pitch.

FAQ

What is the minimum operating voltage for 74AUP2G17FW3-7?

The device is fully specified from 0.8V to 3.6V. At 0.8V, it delivers functional Schmitt behavior with VT+ = 0.3–0.65V and VT− = 0.1–0.6V, and propagation delay of 19.9ns (typ.) into 5pF load - enabling compatibility with emerging sub-1V microcontrollers and energy-harvesting systems.

Does 74AUP2G17FW3-7 support hot insertion or partial power-down?

Yes. Its IOFF circuitry actively disables outputs when VCC = 0V, limiting I/O leakage to ±0.2µA max. This prevents back-current flow from live system buses into the unpowered IC - a requirement for PCIe add-in cards, modular docking stations, and multi-domain power management architectures.

How does the Schmitt trigger hysteresis improve noise immunity?

Hysteresis creates separate input thresholds: VT+ (1.88–2.29V) for rising edges and VT− (0.88–1.24V) for falling edges at 3.0V supply, yielding ΔVT = 0.79–1.31V. This 400–1300mV window rejects noise spikes smaller than the hysteresis gap, preventing multiple transitions on a single edge - critical for button interfaces and slow analog comparator outputs.

Can 74AUP2G17FW3-7 drive a 50pF load reliably?

At 3.3V supply, propagation delay increases to 4.2ns (max) for CL = 30pF; extrapolating from datasheet curves, CL = 50pF yields ~5.5ns (max) delay with <10% waveform degradation. For robust 50pF driving, use 3.0–3.3V supply and verify setup/hold margins - no external buffering needed for most MCU or FPGA interfaces.
