Diodes Incorporated 74AUP1G04FS3-7

Overview

74AUP1G04FS3-7 from Diodes Incorporated is a single CMOS inverter gate with push-pull output, designed for ultra-low-power portable systems operating from 0.8 V to 3.6 V. It features IOFF partial power-down protection, ±4 mA output drive at 3.0 V, <0.9 µA static supply current, and Schmitt-trigger input hysteresis (250 mV typical at 3.0 V), enabling robust signal conditioning in battery-powered wearables and sensor nodes.

For engineers reviewing the 74AUP1G04FS3-7 datasheet, 74AUP1G04FS3-7 pinout, 74AUP1G04FS3-7 application, or 74AUP1G04FS3-7 equivalent, key selection criteria include its 0.8–3.6 V supply range, IOFF-enabled power-gating capability, sub-1 µA ICC, 4.3 ns max propagation delay at 3.3 V/10 pF, and X2-DFN0808-4 package footprint for space-constrained PCB layouts.

Technical Context

This device implements a single positive-logic inverter (Y = A̅) using Advanced Ultra Low Power (AUP) CMOS process technology. Its IOFF circuit actively disables output terminals during power-down, blocking reverse current flow when VCC = 0 V - critical for multi-rail systems with asynchronous power sequencing.

The Schmitt-trigger input provides 250 mV typical hysteresis at VCC = 3.0 V, allowing reliable operation with slow-rising/falling signals from mechanical switches or RC networks. Propagation delay is load- and voltage-dependent: 4.3 ns (max, 3.3 V, 10 pF) to 27.0 ns (max, 1.2 V, 10 pF), supporting both high-speed interface buffering and low-voltage logic level translation.

FAQ

What is the minimum supply voltage for guaranteed operation?

The 74AUP1G04FS3-7 is fully specified from 0.8 V to 3.6 V. At 0.8 V, it delivers functional logic inversion with tPD ≤ 19.8 ns (CL = 10 pF) and VIH/VIL thresholds scaled to 80% and 30% of VCC respectively - enabling use with sub-1 V energy-harvesting sources and ultra-low-power MCUs.

Does the IOFF feature require external biasing or control signals?

No. IOFF is fully automatic and requires no external control: when VCC drops to 0 V, the output enters high-impedance state regardless of input voltage, preventing current backflow from other powered rails. This behavior is intrinsic to the AUP process and needs no enable pin or configuration.

Can this device drive a 50 pF load reliably?

At 3.3 V, the device exhibits tPD ≤ 6.9 ns (CL = 30 pF, TA = –40°C to +125°C). Driving 50 pF exceeds the characterized load range; observed delay would increase significantly (>10 ns), and output rise/fall times may degrade. For >30 pF loads, consider buffer staging or selecting a higher-drive variant.

Is the X2-DFN0808-4 package compatible with standard reflow profiles?

Yes. The lead-free, halogen-free X2-DFN0808-4 package complies with IPC/JEDEC J-STD-020 moisture sensitivity level 1 and supports peak reflow temperatures up to 260°C. Recommended profile follows JEDEC MSLE Class 1 guidelines with ramp rate ≤ 3°C/s and time above 217°C ≤ 60 seconds.
