Product details
Overview
SN74AUP1G17DCKT from Texas Instruments is a single-channel Schmitt-trigger buffer IC in SC70-5 package, operating from 0.8 V to 3.6 V supply, delivering 5.1 ns max propagation delay at 3.3 V, 0.9 µA max ICC, and 4.4 pF typical Cpd - designed for noise-immune signal conditioning in battery-powered portable electronics.
For engineers reviewing the SN74AUP1G17DCKT datasheet, SN74AUP1G17DCKT pinout, SN74AUP1G17DCKT application, or SN74AUP1G17DCKT equivalent, key selection criteria include its hysteresis-enabled input (ΔVT = 0.79 V min at 3 V), Ioff partial-power-down support, 3.6-V I/O tolerance, and ultra-low dynamic/static power consumption across wide VCC range.
Technical Context
The SN74AUP1G17DCKT implements a noninverting Schmitt-trigger logic gate with hysteresis (VT+ − VT−) ranging from 0.07 V at 0.8 V VCC to 0.79 V at 3 V VCC, enabling robust immunity to slow-rising or noisy input signals. Its CMOS push-pull output delivers balanced sourcing/sinking capability up to ±4 mA at 3 V.
It supports partial-power-down via Ioff circuitry, limiting leakage to 0.6 µA max over temperature when VCC = 0 V, and features 3.6-V tolerant inputs independent of supply voltage - critical for mixed-voltage interfacing in modern low-power systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 0.8 V to 3.6 V - enables direct integration into sub-1V logic rails and compatibility with 1.2/1.8/2.5/3.3-V domains |
| tpd (max) | 5.1 ns at 3.3 V, CL = 5 pF - ensures timing-critical point-to-point buffering with minimal latency |
| ICC (max) | 0.9 µA at TA = –40°C to +85°C - extends battery life in always-on sensor or standby circuits |
| Cpd (typ) | 4.4 pF at 3.3 V - reduces dynamic switching power in high-frequency clock/data paths |
| ΔVT (min) | 0.79 V at VCC = 3 V - provides ≥26% hysteresis ratio for reliable noise rejection on slow edges |
| Ioff (max) | 0.6 µA at TA = –40°C to +85°C - prevents back-current damage during hot-insertion or partial system shutdown |
| Input Tolerance | 3.6-V absolute max VI - allows safe interfacing with higher-voltage controllers without level shifters |
Pinout & Package
SN74AUP1G17DCKT uses the SC70-5 (SOT-353) package: 1.25 mm × 2.00 mm body, 0.65 mm pitch, 5-terminal surface-mount configuration with exposed pad not present.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (N.C.) | No internal connection | Unbonded pin - must be left floating or grounded per layout best practice; no electrical function |
| 2 (A) | Input | Schmitt-trigger input with hysteresis; accepts 0–3.6 V signals regardless of VCC |
| 3 (GND) | Ground reference | Primary return path for logic and Ioff leakage current; requires low-inductance PCB connection |
| 4 (Y) | Output | Noninverting CMOS push-pull output; drives loads up to ±4 mA while maintaining rail-to-rail swing |
| 5 (VCC) | Positive supply | Power input for internal logic; bypass capacitor (0.1 µF) required within 2 mm for stable operation |
Key Features
| Feature | Design Value |
|---|---|
| Schmitt-trigger input | Enables clean digital output from slow or noisy analog-like signals (e.g., reset lines, sensor outputs) |
| Ioff partial-power-down | Disables outputs and limits I/O leakage to ≤0.6 µA when VCC = 0 V - essential for hot-swap and multi-rail systems |
| Ultra-low static power | 0.9 µA max ICC across full temperature range - eliminates quiescent drain in always-on IoT edge nodes |
| 3.6-V I/O tolerance | Allows direct interface to 3.3-V or 2.5-V peripherals even when VCC = 0.8 V - simplifies voltage-domain bridging |
| NanoStar™ packaging | SC70-5 footprint enables high-density routing in space-constrained wearables and handheld devices |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schmitt-trigger buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC1G17DCKR | Wider VCC range (1.65–5.5 V); higher ICC (10 µA typ); no Ioff; 3.3-V I/O only | Requires ≥1.65 V supply; unsuitable for sub-1.2-V systems or partial-power-down use cases | Choose when interfacing exclusively with 3.3/5-V logic and lowest cost is priority over power or Ioff |
| NC7SZ17P5X | Same SC70-5 package; VCC = 1.65–5.5 V; ICC = 1 µA max; no Ioff; hysteresis ~0.5 V at 3.3 V | Lacks Ioff and sub-1-V operation; lower hysteresis margin reduces noise immunity on marginal signals | Prefer for legacy 3.3-V designs where ON Semiconductor sourcing is mandated and Ioff is unnecessary |
Compared with SN74LVC1G17DCKR and NC7SZ17P5X, SN74AUP1G17DCKT uniquely supports 0.8-V operation, delivers 10× lower ICC, and includes Ioff - making it the only viable choice for ultra-low-power, mixed-voltage, or hot-plug-sensitive applications.

FAQ
What is the minimum supply voltage for reliable operation of SN74AUP1G17DCKT?
The SN74AUP1G17DCKT is fully specified down to 0.8 V VCC across –40°C to +85°C, with guaranteed hysteresis (ΔVT ≥ 0.07 V), propagation delay (tpd ≤ 22.7 ns), and output drive (IOH/IOL ≥ ±20 µA). Operation below 0.8 V may result in undefined logic thresholds or increased ICC.
Does SN74AUP1G17DCKT support partial-power-down mode, and how is it implemented?
Yes, SN74AUP1G17DCKT supports partial-power-down via its Ioff feature: when VCC = 0 V, all inputs and outputs enter high-impedance state with leakage ≤0.6 µA max. This prevents back-current flow into powered sections of the system, protecting both SN74AUP1G17DCKT and connected devices during hot-swap or rail sequencing.
Can SN74AUP1G17DCKT inputs be driven above its VCC supply voltage?
Yes - SN74AUP1G17DCKT inputs are 3.6-V tolerant regardless of VCC value (0.8–3.6 V). For example, with VCC = 1.2 V, an input signal up to 3.6 V is safely accepted without damage or latch-up, enabling direct interfacing with higher-voltage peripherals without external level shifters.
What is the typical input capacitance of SN74AUP1G17DCKT, and why does it matter?
SN74AUP1G17DCKT has Ci = 1.5 pF typical, measured at VCC or GND. This ultra-low input capacitance minimizes loading on high-impedance sources (e.g., crystal oscillators, sensor outputs), preserving signal rise time and reducing crosstalk in dense routing - critical for maintaining timing margins in high-speed or RF-adjacent layouts.
How does the Schmitt-trigger hysteresis of SN74AUP1G17DCKT improve noise immunity?
SN74AUP1G17DCKT provides programmable hysteresis (ΔVT) from 0.07 V at 0.8 V VCC to 0.79 V at 3 V VCC. This dual-threshold behavior prevents multiple output transitions caused by noise near the switching point - especially effective for cleaning up slow-rising reset lines, mechanical switch bounce, or EMI-contaminated sensor signals without external filtering.
