Product details

Overview

74AUP1G17FW5-7 from Diodes Incorporated is a single Schmitt-trigger buffer IC in X1-DFN1010-6 package, operating from 0.8V to 3.6V supply, delivering ±4mA output drive at 3.0V, with hysteresis of 0.79–1.31V at V_CC = 3.0V, and supporting partial power-down via IOFF. It enables robust signal conditioning in ultra-low-power portable interfaces such as USB-C sideband use, display panel reset lines, and sensor wake-up paths.

For engineers reviewing the 74AUP1G17FW5-7 datasheet, 74AUP1G17FW5-7 pinout, 74AUP1G17FW5-7 application, or 74AUP1G17FW5-7 equivalent, key selection criteria include supply voltage flexibility (0.8–3.6V), Schmitt-trigger input tolerance for slow-rising signals, IOFF-enabled isolation during system sleep states, and DFN1010 footprint compatibility with space-constrained PCB layouts.

Technical Context

This device implements a non-inverting Schmitt-trigger buffer with asymmetric input thresholds: VT+ = 1.61–2.32V and VT− = 0.88–1.24V at V_CC = 3.0V, yielding 0.79–1.31V hysteresis. Its IOFF circuit actively disables output leakage when V_CC = 0V, preventing backfeed into powered-down rails.

Propagation delay ranges from 1.5ns (min) to 4.0ns (max) at 3.3V/CL = 5pF, scaling predictably with load capacitance up to 30pF. Input capacitance is 1.5pF, and power dissipation capacitance is 6.1pF at 3.3V, enabling low-noise, low-energy switching in battery-critical signal paths.

Key Specifications

Parameter	Value and Actual Design Meaning
Supply Voltage Range	0.8V to 3.6V - supports direct interfacing with 1.2V, 1.8V, 2.5V, and 3.3V logic domains without level shifters.
Output Drive	±4mA at 3.0V - sufficient to drive 50Ω transmission lines or multiple CMOS inputs with controlled edge rates.
Hysteresis (ΔVT)	0.79–1.31V at V_CC = 3.0V - rejects noise up to ~400mV peak-to-peak on slow-switching control signals like lid-open sensors or battery fuel-gauge alerts.
IOFF Leakage	±0.5µA max at TA = +25°C - ensures <1µA total standby current when V_CC = 0V and I/O pins float at 0–3.6V.
Propagation Delay	1.5–4.0ns at 3.3V/CL = 5pF - enables sub-5ns timing margin for 100MHz clock enable or interrupt synchronization.
Static Supply Current	0.9µA max - contributes negligible load to coin-cell or energy-harvesting power supplies.
ESD Protection	2kV HBM, 1kV CDM - meets IEC 61000-4-2 Level 2 for handheld device button/switch interface protection.

Pinout & Package

X1-DFN1010-6 package: 1.0mm × 1.0mm × 0.5mm body, 0.35mm pad pitch, 6-terminal leadless construction with exposed thermal pad (Type B). Pin 1 marked by chamfered corner per JEDEC MO-305.

Pin/Terminal	Circuit Role	Design Meaning
1	A (Input)	Schmitt-trigger input with hysteresis; accepts slow edges down to 100ns rise/fall without oscillation.
2	GND	Reference return for all internal logic and output stages; must be connected to PCB ground plane under package.
3	Y (Output)	Push-pull CMOS output; drives high/low actively with matched rise/fall times and no pull-up resistor required.
4	V_CC	Primary power rail; IOFF activates automatically when V_CC drops below 0.2V, disabling Y and isolating A.
5	NC	No internal connection; electrically floating; may be left unconnected or tied to GND for mechanical stability.
6	Thermal Pad	Internally connected to GND; must be soldered to PCB thermal pad for θ_JA = 435°C/W performance and reliability.

Key Features

Feature	Design Value
Ultra-low static power	I_CC ≤ 0.9µA - extends shelf life and runtime in always-on sensor nodes and real-time clocks.
Schmitt-trigger input	250mV typical hysteresis at 3.0V - eliminates need for external RC filtering on noisy mechanical switch or analog comparator outputs.
IOFF partial power-down	Output disabled with <±0.5µA leakage when V_CC = 0 - prevents back-current from live buses into dormant subsystems.
Wide V_CC range	0.8V–3.6V operation - allows direct integration with Li-ion battery discharge curves (2.8–4.2V) via LDO or buck converter output.
Lead-free & green	Halogen- and antimony-free, RoHS-compliant - satisfies IPC-1752A material declaration requirements for EU/China export.

Applications

USB-C Sideband Use

Display Panel Reset

Use Scenario: Conditioning CC line status signals in USB-C port controllers where voltage levels vary between 0.8V (USB PD negotiation) and 3.3V (legacy mode).

IC Role / Device Role / Timing Role: Schmitt-trigger buffer isolates noisy CC pin transitions and provides clean, debounced logic-level output to MCU GPIO.

Use Value: Eliminates false plug/unplug detection caused by slow CC line ramp-up; enables reliable Type-C orientation sensing at <1µA quiescent current.

Use Scenario: Driving active-low RESET# line to TFT-LCD panels in tablets, where host SoC operates at 1.8V but panel requires 3.3V-compatible reset assertion.

IC Role / Device Role / Timing Role: Level-shifting buffer with hysteresis ensures monotonic reset deassertion despite supply droop during panel power-up sequencing.

Use Value: Prevents display initialization lockup due to marginal reset pulse width; supports 100% first-boot success across -40°C to +85°C ambient.

Sensor Wake-Up Path

Low-Power Keypad Interface

Use Scenario: Interfacing MEMS motion sensor INT pin (open-drain, slow rise) to ultra-low-power microcontroller with deep-sleep mode.

IC Role / Device Role / Timing Role: Schmitt-trigger buffer converts weak, slow interrupt edges into fast, rail-to-rail CMOS pulses compatible with MCU wake-up inputs.

Use Value: Reduces wake latency by >3× vs. direct connection; maintains <2µA total system standby current including buffer and sensor.

Use Scenario: Debouncing mechanical keypad matrix rows/columns in medical wearables where ESD exposure and battery life are critical.

IC Role / Device Role / Timing Role: Input buffer with hysteresis suppresses contact bounce (1–10ms) and ESD transients before reaching MCU ADC or GPIO.

Use Value: Achieves >99.99% keypress recognition accuracy without firmware debounce; survives 2kV HBM contact discharge per IEC 61000-4-2.

Equivalent & Alternatives

The following parts are listed as comparable options for similar Schmitt-trigger buffer applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
SN74LVC1G17DBVR	Wider V_CC range (1.65–5.5V); higher drive (±24mA); no IOFF; SOT-23-5 package (2.9mm × 1.6mm).	Requires external pull-up for open-drain inputs; unsuitable for partial power-down systems.	Select when interfacing 5V peripherals or needing higher drive; avoid in battery-powered sleep-mode designs.
74AHC1G17SE-7	Same AUP family but SOT353 package (2.0mm × 2.0mm); identical electrical specs except θ_JA = 371°C/W vs. 435°C/W.	Larger footprint limits use in <10mm² wearable PCBs; thermal performance less optimal in sealed enclosures.	Select when legacy SMT reflow profile or hand-soldering capability is required; prefer FW5 for miniaturized layouts.

Compared with SN74LVC1G17DBVR and 74AHC1G17SE-7, the 74AUP1G17FW5-7 uniquely combines sub-1µA static current, IOFF-enabled rail isolation, and 1.0mm² DFN packaging-making it the only choice for space- and energy-constrained applications requiring guaranteed signal integrity during multi-rail power sequencing.

FAQ

Can 74AUP1G17FW5-7 operate reliably at 0.85V supply?

Yes. The datasheet specifies full functionality down to 0.8V with validated parameters: VT+ = 0.4–0.65V, VT− = 0.15–0.4V, and t_PD ≤ 19.0ns at CL = 5pF. At 0.85V, output drive remains ≥±20µA, ensuring compatibility with 0.9V-core MCUs and energy-harvesting PMIC outputs.

What is the maximum capacitive load this buffer can drive while maintaining specified t_PD?

The device is characterized up to 30pF load capacitance. At CL = 30pF and V_CC = 3.3V, t_PD remains within 2.5–7.5ns (min–max), meeting timing budgets for 100MHz clock-enable paths. For loads >30pF, propagation delay increases linearly (~0.2ns/pF), but output drive capability remains intact up to ±20mA.

Is the NC pin on the X1-DFN1010-6 package required to be grounded?

No. Pin 5 is internally unconnected and electrically isolated. It may be left floating, tied to GND for mechanical reinforcement, or connected to a thermal pad extension-none affects electrical performance. Diodes Incorporated's AP02002 layout guide treats it as optional for solder joint reliability only.

Does IOFF function activate when V_CC is pulled to 0.1V, or only at true 0V?

IOFF activates when V_CC falls below 0.2V, per datasheet Section 7 (Recommended Operating Conditions). At V_CC = 0.1V, IOFF is fully engaged: output leakage is limited to ±0.5µA max, and input-to-output isolation exceeds 100MΩ, preventing backfeed from 3.3V I/O lines into a partially powered subsystem.
