Product details
Overview
74AUP1G17SE-7 from Diodes Incorporated is a single-channel Schmitt-trigger buffer IC in SOT353 package, operating from 0.8V to 3.6V supply, delivering ±4mA output drive at 3.0V, with <0.9µA static current and 250mV typical hysteresis at VCC = 3.0V, used for noise-immune signal conditioning in portable battery-powered interfaces.
For engineers reviewing the 74AUP1G17SE-7 datasheet, 74AUP1G17SE-7 pinout, 74AUP1G17SE-7 application, or 74AUP1G17SE-7 equivalent, key selection criteria include ultra-low ICC, IOFF-enabled partial power-down capability, Schmitt-trigger input threshold stability across voltage rails, and SOT353 thermal resistance (θJA = 371°C/W).
Technical Context
This device implements a non-inverting positive Boolean function (Y = A) with hysteresis-based input thresholding-VT+ = 1.61–2.32V and VT− = 0.88–1.24V at 3.0V supply-enabling robust operation with slow-rising or noisy digital signals. Its IOFF circuit actively disables outputs during power-down to prevent backflow current.
Designed for battery-constrained systems, it achieves 2.7ns typical propagation delay (tPD) at 3.3V/CL=5pF and maintains stable switching performance across −40°C to +125°C ambient, with Cpd = 6.1pF at 3.3V enabling low dynamic power consumption.
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 standard CMOS loads and short PCB traces without external buffering. |
| Static Current (ICC) | <0.9µA - enables multi-year operation in always-on sensor nodes or real-time clock backup paths. |
| Hysteresis (∆VT) | 0.79–1.31V at 3.0V - rejects up to ~1.3V of input noise while maintaining clean output transitions. |
| Propagation Delay | 1.5–4.0ns at 3.3V/CL=5–30pF - meets timing requirements for sub-100MHz data path conditioning in wearables and IoT edge devices. |
| IOFF Leakage | ±0.2µA max at 25°C - ensures safe isolation when VCC is unpowered while other system rails remain active. |
| ESD Protection | 2kV HBM, 1kV CDM - exceeds IEC 61000-4-2 Level 2 for handheld product front-end signal lines. |
Pinout & Package
SOT353 package: 2.0mm × 2.0mm × 1.1mm body, 0.65mm lead pitch, 5-pin configuration with exposed pad not electrically connected.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | A | CMOS Schmitt-trigger input - accepts slow or noisy signals; threshold hysteresis prevents chatter on marginal edges. |
| 2 | GND | Ground reference - must be low-impedance connection to minimize switching noise coupling into threshold detection. |
| 3 | Y | Push-pull output - drives high/low actively; no pull-up required; compatible with CMOS, TTL, and LVTTL loads. |
| 4 | VCC | Power supply - decoupling capacitor (100nF) required within 3mm for stable Schmitt-trigger operation. |
| 5 | NC | No connection - internally unconnected; may be left floating or tied to GND for mechanical stability only. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low static power | ICC < 0.9µA enables >10-year battery life in coin-cell-powered remote sensors. |
| Schmitt-trigger input | 250mV typical hysteresis at 3.0V eliminates need for external RC filtering on noisy microcontroller GPIOs. |
| IOFF partial power-down | Prevents back-current flow when VCC = 0V while A/Y pins remain biased by other powered subsystems. |
| Wide VCC range | 0.8V–3.6V operation allows direct use with energy-harvesting PMIC outputs and legacy 3.3V/2.5V peripherals. |
| Lead-free & green compliance | Halogen- and antimony-free, RoHS-compliant construction meets IPC-1752A material declaration requirements. |

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 | Higher IOH/IOL (±32mA), wider VCC (1.65–5.5V), no IOFF, higher ICC (10µA) | Requires external power sequencing; unsuitable for mixed-voltage partial-power-down systems | Select when driving heavier capacitive loads (>50pF) or interfacing with 5V peripherals. |
| 74LVC1G17GW,125 | Same AUP-family specs but in SC-70 package (2.2mm × 2.2mm); θJA = 330°C/W vs. 371°C/W | Marginally better thermal performance but larger footprint than SOT353 | Select when board layout permits slightly larger package and thermal margin is critical above 85°C ambient. |
Compared with SN74LVC1G17DBVR and 74LVC1G17GW,125, the 74AUP1G17SE-7 uniquely combines sub-µA static current, IOFF protection, and SOT353 miniaturization-making it optimal for space- and energy-constrained wearable and medical patch designs where power sequencing complexity must be minimized.

FAQ
What is the minimum supply voltage for guaranteed Schmitt-trigger operation?
The device is fully specified from 0.8V to 3.6V. At 0.8V, VT+ = 0.4–0.65V and VT− = 0.15–0.4V, providing ≥0.07V hysteresis-sufficient for noise rejection in energy-harvesting systems where supply may dip below 1.0V during peak load.
Can the NC pin be used as a heatsink pad?
No. Pin 5 is internally unconnected and not bonded to the die paddle. It must remain electrically floating or grounded solely for mechanical reinforcement; connecting it to thermal planes provides no thermal benefit due to lack of internal thermal path.
How does IOFF behave when VCC = 0V but input A is pulled to 3.3V?
IOFF activates automatically when VCC drops below ~0.2V, limiting reverse current through A to ±0.2µA max at 25°C. This prevents backfeed into a powered-down domain while allowing safe hot-plug operation of peripheral modules.
Is the 250mV hysteresis value fixed or supply-dependent?
Hysteresis varies with VCC: ∆VT = 0.79–1.31V at 3.0V, 0.27–0.66V at 1.65V, and 0.07–0.5V at 0.8V. The 250mV figure is a typical value at 3.0V-not a guaranteed minimum-and scales approximately linearly with supply voltage.
