Product details
Overview
SN74AUP1G17YFPR from Texas Instruments is a single-channel Schmitt-trigger buffer IC designed for signal conditioning in ultra-low-power portable systems. It operates across 0.8 V to 3.6 V, delivers 5.1 ns max propagation delay at 3.3 V, features 1.5 pF typical input capacitance and 0.9 µA max ICC, and is used in point-to-point signal integrity-critical paths such as power-on reset timing and noise-prone sensor interface lines.
For engineers reviewing the SN74AUP1G17YFPR datasheet, SN74AUP1G17YFPR pinout, SN74AUP1G17YFPR application, or SN74AUP1G17YFPR equivalent, key selection criteria include its Schmitt-trigger hysteresis (0.07–1.31 V), Ioff-enabled partial-power-down capability, 3.6-V I/O tolerance for mixed-voltage domains, and DSBGA-4 package footprint compatibility with space-constrained mobile PCB layouts.
Technical Context
This device implements a noninverting Schmitt-trigger logic gate with hysteresis (ΔVT) ranging from 0.07 V at 0.8 V VCC to 1.31 V at 3.0 V VCC, enabling robust immunity against slow-rising or noisy input signals. Its Ioff circuitry actively disables outputs during power-down, limiting leakage to ≤0.6 µA over –40°C to +85°C.
The SN74AUP1G17YFPR uses standard CMOS inputs with 1.5 pF typical Ci and balanced push-pull outputs capable of ±4 mA drive at 3.0 V, while maintaining low dynamic power (Cpd = 4.4 pF typical at 3.3 V) and <10% overshoot/undershoot relative to VCC.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 0.8 V to 3.6 V - supports direct interfacing with 1.2 V, 1.8 V, 2.5 V, and 3.3 V logic domains without level shifters |
| tpd Max | 5.1 ns at 3.3 V - enables reliable timing in sub-200 MHz digital control loops and power sequencing |
| ICC Max | 0.9 µA - extends battery life in always-on sensor nodes and wearable devices |
| ΔVT (Hysteresis) | 0.79 V at 3.0 V VCC - rejects >790 mV of input noise without false triggering |
| Ioff Max | 0.6 µA at –40°C to +85°C - prevents backflow current during partial system shutdown |
| Input Capacitance | 1.5 pF typical - minimizes loading on high-impedance sources like crystal oscillators or analog comparators |
| IOH/IOL | ±4 mA at 3.0 V - drives moderate capacitive loads (≤30 pF) without external buffering |
Pinout & Package
SN74AUP1G17YFPR uses a 4-pin DSBGA (Die Size Ball Grid Array) package measuring 0.76 mm × 0.76 mm with 0.4-mm ball pitch. The package places all terminals on the bottom surface in a 2×2 array; no exposed pad or thermal slug is present.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A | Input | Schmitt-trigger input with VT+ = 1.88 V / VT– = 0.88 V at 3.0 V VCC; accepts overvoltage up to 4.6 V |
| Y | Output | Noninverting CMOS output with rail-to-rail swing; sinks/sources up to ±4 mA |
| VCC | Power | Primary supply pin; requires local 0.1-µF bypass capacitor placed within 2 mm |
| GND | Ground | Reference return path for all I/O and internal logic; must connect to solid ground plane |
Key Features
| Feature | Design Value |
|---|---|
| Schmitt-trigger input | Enables clean switching from slow-rising signals (e.g., RC power-up circuits) and rejects >790 mV noise at 3.0 V |
| Ioff partial-power-down | Disables outputs and limits leakage to ≤0.6 µA when VCC = 0 V - critical for hot-plug and multi-rail systems |
| 3.6-V I/O tolerance | Allows A and Y pins to accept inputs up to 4.6 V even when VCC = 0.8 V - simplifies mixed-voltage interconnect |
| NanoStar™ DSBGA packaging | 0.76 mm × 0.76 mm footprint with 0.4-mm pitch - reduces board area by >60% vs. SOT-23 |
| Low dynamic power | Cpd = 4.4 pF at 3.3 V - cuts switching energy by ~40% vs. LVC-family buffers at same frequency |

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 | Higher ICC (10 µA typ), wider tpd range (3.5–15 ns), 1.65–5.5 V VCC range, SC70-5 package (1.25 × 2.00 mm) | Supports 5-V tolerant operation but consumes >10× more static power; larger footprint | Choose when 5-V interface compatibility is required and power budget allows ≥10 µA ICC |
| NC7SZ17P5X | Lower hysteresis (ΔVT ≈ 0.3 V at 3.3 V), 1.65–5.5 V VCC, SOT-353-5 package (1.2 × 1.8 mm), Cpd = 4.5 pF | Less noise immunity on slow edges; not specified for Ioff or partial-power-down use | Choose for cost-sensitive, non-power-critical applications where Schmitt threshold margin is sufficient |
Compared with SN74LVC1G17DCKR and NC7SZ17P5X, SN74AUP1G17YFPR uniquely combines sub-1-µA static current, DSBGA-4 miniaturization, and guaranteed Ioff behavior - making it the only option qualified for battery-operated, space-constrained, and hot-pluggable designs requiring zero-current isolation during power-down.

FAQ
What is the maximum operating temperature range for SN74AUP1G17YFPR?
The SN74AUP1G17YFPR is fully specified from –40°C to +85°C ambient temperature. All electrical characteristics-including propagation delay, input thresholds, and Ioff leakage-are guaranteed across this range. Thermal resistance values (RθJA = 179.3°C/W, RθJB = 58.3°C/W) confirm suitability for compact PCB layouts without forced airflow.
Does SN74AUP1G17YFPR support partial-power-down mode, and how is it implemented?
Yes, SN74AUP1G17YFPR supports partial-power-down via its Ioff feature. When VCC = 0 V, all I/O pins enter high-impedance state with leakage ≤0.6 µA over –40°C to +85°C. This prevents backflow current into powered-down sections of a system, protecting both SN74AUP1G17YFPR and upstream components during hot-swap or multi-rail sequencing.
What is the input hysteresis (ΔVT) of SN74AUP1G17YFPR at 1.8 V supply?
At 1.8 V VCC and TA = 25°C, SN74AUP1G17YFPR exhibits ΔVT = 0.27 V (VT+ = 1.11 V, VT– = 0.84 V). Over –40°C to +85°C, ΔVT remains 0.18–0.66 V, ensuring consistent noise rejection across temperature for applications like RC-based power-on reset generators.
Can SN74AUP1G17YFPR be used with a 0.8 V supply, and what performance trade-offs apply?
Yes, SN74AUP1G17YFPR operates down to 0.8 V VCC. At this voltage, tpd increases to 22.7 ns (CL = 5 pF), VT+ = 0.6 V, and IOH/IOL drops to ±20 µA. It remains functional for ultra-low-power always-on monitoring but is unsuitable for high-speed data paths below 1.2 V.
Is SN74AUP1G17YFPR pin-compatible with other AUP-family single-gate devices in the same DSBGA-4 package?
No-SN74AUP1G17YFPR is not pin-compatible with other AUP gates (e.g., SN74AUP1G04YFPR or SN74AUP1G14YFPR) in the YFP package. While all share the 2×2 DSBGA-4 footprint, pin functions differ: SN74AUP1G17YFPR assigns A/Y/VCC/GND to balls A1/B1/A2/B2, whereas inverters and Schmitt inverters reassign Y to different locations per logic function.
