Product details
Overview
SN74AUP1G17DSFR from Texas Instruments is a low-power single Schmitt-trigger buffer IC in a 6-pin SON package (1.00 mm × 1.00 mm), operating across 0.8 V to 3.6 V supply voltage, delivering 5.1 ns max propagation delay at 3.3 V, 4.4 pF typical dynamic power capacitance, and Ioff-enabled partial-power-down capability for battery-powered portable systems.
For engineers reviewing the SN74AUP1G17DSFR datasheet, SN74AUP1G17DSFR pinout, SN74AUP1G17DSFR application, or SN74AUP1G17DSFR equivalent, key selection considerations include its Schmitt-trigger input hysteresis (0.79–1.31 V ΔVT at 3 V), ultra-low ICC (0.9 µA max), 3.6-V I/O tolerance for mixed-voltage interfacing, and validated performance in point-to-point signal conditioning with slow-edge immunity.
Technical Context
This device implements a noninverting Schmitt-trigger buffer with positive-logic behavior and no enable control - input A directly drives output Y with hysteresis-based noise rejection. Its architecture supports stable operation under slow-rising/falling inputs and suppresses false triggering in noisy environments such as PCB reset lines or sensor interface paths.
The AUP family uses advanced CMOS process technology to achieve sub-1-µA static current across full VCC range while maintaining balanced push-pull output drive (±4 mA at 3 V) and low input capacitance (1.5 pF typical), enabling clean signal integrity in space-constrained, low-power embedded designs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 0.8 V to 3.6 V - enables direct integration into multi-rail systems including 1.2-V, 1.8-V, 2.5-V, and 3.3-V domains without level shifters |
| tpd (max) | 5.1 ns at 3.3 V, CL = 5 pF - ensures timing-critical signal buffering in high-speed digital interfaces up to ~100 MHz |
| ICC (max) | 0.9 µA - extends battery life in always-on IoT sensors and wearable devices by minimizing quiescent power draw |
| ΔVT (hysteresis) | 0.79–1.31 V at 3 V - rejects up to ±650 mV of input noise on reset or wake-up lines without external RC filtering |
| Ioff Leakage | 0.6 µA max at 85°C - prevents back-current damage during hot-insertion or partial system power-down sequences |
| Ci / Cpd | 1.5 pF / 4.4 pF - reduces capacitive loading on driving sources and minimizes dynamic switching power in dense routing |
| IOH/IOL | ±4 mA at 3 V - provides sufficient drive strength for fan-out to multiple CMOS loads or short PCB traces without buffers |
Pinout & Package
SN74AUP1G17DSFR is housed in a 6-pin SON (Small Outline No-Lead) package measuring 1.00 mm × 1.00 mm with wettable flanks, optimized for automated optical inspection and high-density PCB assembly.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A | Input | Schmitt-triggered digital input accepting 0–3.6 V signals; tolerant of slow edges and noise up to hysteresis threshold |
| Y | Output | Noninverting CMOS output with balanced sourcing/sinking capability; drives logic-high or logic-low based on A state |
| VCC | Power | Primary supply pin - must be decoupled with ≤100 nF capacitor placed within 2 mm for stable operation |
| GND | Ground | Reference return path for all internal circuitry and I/O; requires low-inductance connection to system ground plane |
| N.C. | No Connection | Two pins (1 and 5) are internally unconnected - must remain floating or tied to GND per layout guidelines; not usable as I/O |
Key Features
| Feature | Design Value |
|---|---|
| Schmitt-trigger input | Enables reliable signal conditioning of slow or noisy inputs (e.g., mechanical switch debouncing, reset line stabilization) |
| Ioff partial-power-down | Prevents damaging back-current flow when VCC = 0 V - critical for hot-swap and multi-voltage domain isolation |
| 3.6-V I/O tolerance | Allows safe interfacing with higher-voltage peripherals (e.g., 3.3-V microcontrollers driving 1.8-V logic rails) |
| NanoStar™ packaging | Die-as-package construction reduces parasitic inductance/capacitance and improves thermal resistance vs. traditional SOT/SC70 |
| Low noise overshoot/undershoot | <10% of VCC - eliminates need for external termination resistors in point-to-point routing |
Applications
| Industrial Sensor Interface | Portable Device Power Sequencing |
|---|---|
Use Scenario: Conditioning analog sensor output or mechanical switch signal before ADC sampling or MCU GPIO input. IC Role / Device Role / Timing Role: Schmitt-trigger buffer cleans slow-rising thermistor or reed-switch signals and rejects EMI-induced glitches. Use Value: Eliminates external RC filters and software debouncing, reducing BOM count and firmware complexity while improving reliability. | Use Scenario: Generating controlled power-on reset pulse for microcontroller or FPGA configuration sequence. IC Role / Device Role / Timing Role: Buffers RC-generated delay signal to produce clean, noise-immune active-high reset assertion.

IC Role / Device Role / Timing Role: Voltage-domain agnostic buffer preserves logic states across rail boundaries using Ioff and 3.6-V I/O tolerance. Use Value: Enables seamless integration without redesigning power tree or adding discrete FET translators - reduces layout area and validation effort. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Schmitt-trigger buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC1G17DSFR | Higher ICC (10 µA typ), narrower VCC range (1.65–5.5 V), no Ioff support | Not suitable for partial-power-down or sub-1.65-V operation; better for 3.3/5-V legacy systems | Choose when higher drive strength (±24 mA) and 5-V compatibility outweigh ultra-low power needs |
| NC7SZ17P5X | Smaller 5-pin SC70 package, lower hysteresis (ΔVT ≈ 0.3 V at 3.3 V), no Ioff | Limited noise immunity in high-EMI environments; unsuitable for hot-swap or multi-rail isolation | Prefer for cost-sensitive, space-constrained designs where full AUP-level hysteresis and Ioff are unnecessary |
Compared with SN74LVC1G17DSFR and NC7SZ17P5X, SN74AUP1G17DSFR uniquely combines sub-1-µA quiescent current, 0.8-V minimum operation, and Ioff protection - making it the only option qualified for battery-backed, multi-voltage, and hot-pluggable embedded subsystems.

FAQ
What is the maximum operating temperature for SN74AUP1G17DSFR?
The SN74AUP1G17DSFR is rated for continuous operation from –40°C to +85°C ambient temperature. Its thermal metrics - including RθJA = 386.2°C/W for the DSF package - ensure reliable performance in sealed industrial enclosures and handheld devices without forced airflow, provided PCB copper area and decoupling meet TI layout guidelines.
Does SN74AUP1G17DSFR support partial power-down mode?
Yes, SN74AUP1G17DSFR fully supports partial power-down via its Ioff feature. When VCC = 0 V, all I/O pins enter high-impedance state with leakage limited to 0.6 µA max at 85°C, preventing back-current damage during hot-swap or multi-rail sequencing - a capability not present in standard LVC or AHC logic families.
What is the input hysteresis voltage (ΔVT) of SN74AUP1G17DSFR at 1.8 V supply?
At VCC = 1.8 V and TA = 25°C, SN74AUP1G17DSFR exhibits ΔVT = 0.27–0.66 V. This hysteresis window rejects noise spikes up to ±330 mV on input A, enabling robust operation in electrically noisy environments like motor-control feedback loops or industrial sensor nodes without external filtering components.
Can SN74AUP1G17DSFR be used with a 1.2-V supply?
Yes, SN74AUP1G17DSFR operates reliably down to 0.8 V, so 1.2-V supply is well within specification. At 1.2 V, it delivers tpd ≤14.6 ns (CL = 5 pF), VT+ = 0.53–0.9 V, and ICC ≤0.9 µA - making it ideal for ultra-low-power microcontroller peripherals and energy-harvesting sensor nodes where supply headroom is minimal.
Is SN74AUP1G17DSFR pin-compatible with other AUP1G17 variants?
SN74AUP1G17DSFR shares identical logic function and pin assignment (A, Y, VCC, GND, N.C., N.C.) with other 6-pin SON variants like SN74AUP1G17DRY, but differs from 5-pin packages (DBV, DCK, DPW) which lack one N.C. pin. Always verify footprint and solder mask clearance - DSF uses 1.00 mm × 1.00 mm body with wettable flanks, distinct from DRY's 1.00 mm × 1.45 mm outline.
