Diodes Incorporated 74AUP1G86FW5-7

Overview

74AUP1G86FW5-7 from Diodes Incorporated is a single 2-input exclusive-OR (XOR) gate in the Advanced Ultra Low Power (AUP) CMOS logic family, designed for battery-powered portable electronics. It operates across 0.8V–3.6V supply, delivers ±4mA output drive at 3.0V, features Schmitt-trigger inputs with ~250mV hysteresis at V_CC = 3.0V, and supports partial power-down via IOFF circuitry to prevent backflow current. It is used in signal-level logic comparison and data path control in ultra-compact handheld devices.

For engineers reviewing the 74AUP1G86FW5-7 datasheet, 74AUP1G86FW5-7 pinout, 74AUP1G86FW5-7 application, or 74AUP1G86FW5-7 equivalent, key selection criteria include its 1.0mm × 1.0mm X1-DFN1010-6 package, sub-1µA static ICC, <5ns typical propagation delay at 3.3V/15pF, and guaranteed IOFF behavior for mixed-voltage system interfacing.

Technical Context

This XOR gate implements the Boolean function Y = A ⊕ B using standard push-pull CMOS output stages. Its Schmitt-trigger inputs provide noise immunity with defined hysteresis (~250mV at 3.0V), enabling robust operation with slow-rising or noisy signals without external conditioning.

The IOFF feature actively disables outputs when V_CC = 0V, limiting leakage to ≤0.6µA over temperature and preventing current backflow into powered-down sections-critical for partial-power-down architectures in multi-rail SoC subsystems.

FAQ

What is the maximum recommended operating temperature for continuous use?

The 74AUP1G86FW5-7 is rated for continuous operation from –40°C to +125°C ambient temperature. Junction temperature must remain ≤+150°C; with θ_JA = 435°C/W and typical power dissipation <10µW, derating is unnecessary below 100mW total board power.

Can Pin 6 (NC) be grounded or left floating in layout?

Pin 6 is internally unconnected and must be left floating per Diodes Incorporated's AP02002 layout guidelines. Grounding it may cause unintended parasitic coupling or violate thermal pad clearance rules; no electrical benefit or risk mitigation is achieved.

Does the IOFF feature require external biasing or control signals?

No. IOFF activates automatically when V_CC drops to 0V; no external enable/disable signal is needed. The output enters high-impedance state with leakage ≤0.6µA, and resumes normal operation immediately upon V_CC restoration.

How does Schmitt-trigger input behavior affect timing analysis?

Schmitt-trigger inputs introduce fixed hysteresis (~250mV), meaning input transition thresholds differ for rising/falling edges. This eliminates metastability from slow edges but requires verifying setup/hold margins against the actual crossing points-not nominal V_CC/2-when interfacing with non-Schmitt sources.
