Diodes Incorporated 74AUP2G17FZ4-7

Overview

74AUP2G17FZ4-7 from Diodes Incorporated is a dual Schmitt trigger buffer IC in the Advanced Ultra Low Power (AUP) CMOS logic family, designed for noise-immune signal conditioning in battery-powered systems. It operates from 0.8V to 3.6V, delivers ±4mA output drive at 3.0V, features IOFF partial power-down protection, and uses X2-DFN1410-6 (1.4mm × 1.0mm) packaging - ideal for space-constrained portable electronics.

For engineers reviewing the 74AUP2G17FZ4-7 datasheet, 74AUP2G17FZ4-7 pinout, 74AUP2G17FZ4-7 application, or 74AUP2G17FZ4-7 equivalent, key selection criteria include supply voltage flexibility (0.8–3.6V), Schmitt-trigger hysteresis (min 0.07V @ 0.8V), ultra-low ICC (<0.9µA), IOFF leakage (<±0.2µA), and DFN1410 footprint compatibility with high-density PCB layouts.

Technical Context

This dual non-inverting Schmitt trigger buffer implements Y = A logic per channel, with independent input threshold hysteresis (ΔVT) enabling robust operation with slow-rising or noisy signals. Each channel supports rail-to-rail input and output swing across the full 0.8V–3.6V VCC range.

The IOFF circuit actively disables outputs during power-down, preventing back-current flow when VCC = 0V while inputs remain biased - critical for multi-rail system interoperability. Input capacitance is 2.0pF, and propagation delay ranges from 1.1ns (3.3V, CL=5pF) to 4.3ns (3.3V, CL=30pF).

Key Specifications

Pinout & Package

FAQ

What is the minimum operating voltage for 74AUP2G17FZ4-7?

The device is fully specified from 0.8V to 3.6V. At 0.8V, it maintains functional Schmitt thresholds (VT+ = 0.3V, VT− = 0.1V) and delivers usable output drive (±20µA), enabling direct interface with emerging sub-1V microcontrollers and energy-harvesting PMICs.

Does 74AUP2G17FZ4-7 support hot insertion or partial power-down?

Yes - its IOFF circuitry actively disables outputs when VCC drops below ~0.2V, blocking current backflow from live inputs into a powered-down domain. This feature is validated per JESD78 latch-up testing and supports safe hot-plug operation in modular systems.

How does the Schmitt trigger hysteresis improve system reliability?

With ΔVT = 0.79V minimum at 3.0V, the device rejects noise spikes up to 26% of VCC amplitude on input edges. This eliminates false triggering in mechanically noisy environments (e.g., button presses, relay contacts) and removes the need for external RC filters or firmware debouncing routines.

Can 74AUP2G17FZ4-7 drive standard 50pF CMOS loads at 3.3V?

Yes - at 3.3V, propagation delay is 4.3ns (max) into 30pF, and output drive remains ±4mA. For 50pF loads, delay increases to ~5.8ns (extrapolated from CL vs. tPD curves), well within timing budgets for non-critical control signals like enable lines or status indicators.
