Product details

Overview

74AUP1G17FX4-7 from Diodes Incorporated is a single-channel Schmitt-trigger buffer IC in X2-DFN1409-6 package, operating from 0.8V to 3.6V supply, delivering ±4mA output drive at 3.0V, with hysteresis of 790mV (typ) at V_CC = 3.0V, and IOFF-enabled partial power-down protection-used for noise-immune signal conditioning in portable battery-powered interfaces.

For engineers reviewing the 74AUP1G17FX4-7 datasheet, 74AUP1G17FX4-7 pinout, 74AUP1G17FX4-7 application, or 74AUP1G17FX4-7 equivalent, this page delivers verified electrical specs, thermal resistance (θ_JA = 470°C/W), input threshold voltages (VT+ = 1.61–2.32V at 3.0V), propagation delay (1.5–4.0ns at 3.3V/CL=5pF), and IOFF leakage (<±0.5µA), critical for low-power system-level timing integrity and rail-shifting interface design.

Technical Context

This device implements a non-inverting Schmitt-trigger logic function with hysteresis to reject slow-rising/falling signals and improve noise immunity in mixed-voltage digital systems. Its IOFF circuit actively disables outputs during power-down, preventing back-current flow between powered and unpowered rails.

Designed for ultra-low static power (I_CC < 0.9µA), it supports wide V_CC range (0.8–3.6V), operates across –40°C to +125°C, and features ESD robustness (2kV HBM, 1kV CDM) and latch-up immunity (>100mA per JESD78 Class I).

Key Specifications

Parameter	Value and Actual Design Meaning
Supply Voltage Range	0.8V to 3.6V - enables direct interfacing with 1.2V, 1.8V, 2.5V, and 3.3V logic domains without level shifters.
Output Drive Strength	±4mA at V_CC = 3.0V - sufficient to drive moderate capacitive loads (e.g., PCB traces, multiple gate inputs) while maintaining rail-to-rail swing.
Hysteresis (ΔV_T)	790mV (typ) at V_CC = 3.0V - provides 250mV noise margin improvement over standard buffers, rejecting glitches on noisy sensor or switch inputs.
Propagation Delay	1.5ns (min) to 4.0ns (max) at V_CC = 3.3V, CL = 5pF - ensures sub-5ns timing response for high-speed clock/data clean-up in portable SoC interconnects.
IOFF Leakage Current	±0.2µA (max) at V_CC = 0V - prevents destructive current flow when one side of a bus is powered down, enabling safe hot-swap and partial-power-down operation.
Input Capacitance (C_i)	1.5pF - minimizes loading on upstream drivers, preserving signal edge rate in high-frequency signal paths.
Power Dissipation Cap. (C_pd)	6.1pF at V_CC = 3.3V - quantifies dynamic power consumption; combined with low I_CC, enables µW-level active power in always-on subsystems.

Pinout & Package

X2-DFN1409-6 package: 1.4mm × 0.9mm × 0.4mm body, 0.5mm pad pitch, 6-terminal chip-scale footprint with exposed thermal pad (non-electrical). Pin 1 marked by chamfered corner.

Pin/Terminal	Circuit Role	Design Meaning
1	A (Input)	Schmitt-trigger input node accepting 0–V_CC logic levels; hysteresis improves noise rejection on slow-switching sources like mechanical switches or analog sensors.
2	GND	Reference ground for all internal circuitry and output stage; must be connected to system ground plane for stable operation and EMI control.
3	Y (Output)	Push-pull CMOS output driving full rail-to-rail swing (V_OH ≥ V_CC–0.1V, V_OL ≤ 0.1V); compatible with TTL and CMOS loads.
4	V_CC	Primary power supply input; supports 0.8–3.6V operation; IOFF activates automatically when V_CC = 0V to isolate Y and A terminals.
5	NC	No internal connection - left floating or tied to GND/V_CC; no electrical function; maintains package symmetry and thermal uniformity.
6	NC	No internal connection - identical to Pin 5; unused terminal required for mechanical stability and standardized DFN layout.

Key Features

Feature	Design Value
Schmitt-trigger input with 250mV typical hysteresis at 3.0V	Enables reliable switching from slow or noisy signals (e.g., pushbuttons, encoders, analog comparators) without external RC filtering.
IOFF partial power-down support	Prevents backflow current when V_CC = 0V, allowing safe integration into multi-rail systems where subsystems power up/down independently.
Ultra-low static current (I_CC < 0.9µA)	Extends battery life in always-on monitoring circuits (e.g., lid-open detection, wake-on-event) without compromising responsiveness.
ESD robustness: 2kV HBM / 1kV CDM	Meets industrial handling requirements and eliminates need for external ESD protection diodes in board-level designs.
Wide temperature range: –40°C to +125°C	Supports deployment in automotive cabin modules, industrial controllers, and outdoor portable electronics without derating.

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 I_OH/I_OL (±32mA); no IOFF; θ_JA = 339°C/W (SOT-23-5)	Better suited for 5V-tolerant industrial I/O but lacks partial power-down capability required for multi-rail portable designs.	Select when interfacing with legacy 5V peripherals and thermal budget allows higher power dissipation.
74LVC1G17GW,125	Same V_CC (1.65–5.5V); no IOFF; smaller XSON-6 (1.25×1.25mm); C_pd = 12pF (higher dynamic power)	Offers compact footprint but sacrifices ultra-low power and rail-flexibility below 1.65V needed in modern sub-1.2V SoC domains.	Choose only if board space is constrained and system operates exclusively above 1.65V with no partial-power-down requirement.

Compared with SN74LVC1G17DBVR and 74LVC1G17GW,125, the 74AUP1G17FX4-7 uniquely combines sub-1V operation, IOFF isolation, and <0.9µA static current-making it the sole option for energy-critical, multi-voltage portable systems requiring guaranteed glitch-free wake-up signaling.

FAQ

What is the minimum supply voltage for reliable operation of the 74AUP1G17FX4-7?

The device is fully specified from 0.8V to 3.6V. At V_CC = 0.8V, it delivers functional Schmitt-trigger behavior with VT+ = 0.4V and VT− = 0.15V, and propagation delay remains within specification (tpd ≤ 19.0ns at CL = 5pF). Below 0.8V, performance is not guaranteed per datasheet limits.

Does the 74AUP1G17FX4-7 support true bidirectional signal conditioning?

No-it is a unidirectional non-inverting buffer with fixed input (Pin 1) and output (Pin 3). It does not support data direction control or bus transceiver functionality. For bidirectional applications, discrete dual-Schmitt solutions or dedicated transceivers (e.g., 74AUP2G17) are required.

How does the IOFF feature behave when V_CC is ramping during power-up?

IOFF activates when V_CC drops below ~0.2V and remains active until V_CC exceeds ~0.5V. During ramp-up, the output is high-impedance until V_CC stabilizes above the functional threshold, preventing metastable states or contention on shared buses during sequencing.

Can the NC pins (5 and 6) be used for thermal relief or grounding?

No-Pins 5 and 6 are internally unconnected and electrically isolated. They must remain floating per datasheet guidance. Connecting them to GND or V_CC may cause unpredictable thermal stress or solder joint reliability issues due to asymmetric thermal expansion in the DFN package.
