Product details
Overview
SN74AUP1G17DPWR from Texas Instruments is a low-power single Schmitt-trigger buffer in X2SON-5 package, operating from 0.8 V to 3.6 V supply, delivering 5.1 ns max propagation delay at 3.3 V, 4.4 pF typical dynamic power capacitance, and 0.9 µA max ICC - designed for noise-immune signal conditioning in battery-powered portable systems.
For engineers reviewing the SN74AUP1G17DPWR datasheet, SN74AUP1G17DPWR pinout, SN74AUP1G17DPWR application, or SN74AUP1G17DPWR equivalent, key selection criteria include Schmitt-trigger hysteresis (0.79 V min at 3 V), Ioff partial-power-down support, 3.6-V I/O tolerance for mixed-voltage interfacing, and ultra-low input capacitance (1.5 pF) enabling high-speed point-to-point routing with minimal loading.
Technical Context
This device implements a noninverting Schmitt-trigger gate with hysteresis (ΔVT = 0.79 V min at VCC = 3 V), enabling robust immunity to slow-rising or noisy input signals. Its balanced CMOS push-pull output drives ±4 mA at 3 V while maintaining rail-to-rail VOH/VOL performance across the full 0.8–3.6 V VCC range.
The Ioff feature actively disables outputs during power-down, limiting leakage to 0.6 µA max over temperature, and its 3.6-V tolerant inputs allow safe interfacing with higher-voltage logic without level shifters - critical for mixed-mode signal domains in compact portable designs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 0.8 V to 3.6 V - supports direct connection to Li-ion battery rails, LDO outputs, and multi-rail SoC interfaces without external regulation |
| tpd Max | 5.1 ns at 3.3 V, CL = 5 pF - enables reliable timing in sub-200 MHz digital control paths with margin |
| ICC Max | 0.9 µA at TA = –40°C to +85°C - extends battery life in always-on sensor nodes and sleep-mode peripherals |
| ΔVT Min | 0.79 V at VCC = 3 V - provides ≥26% hysteresis ratio for stable switching on RC-debounced or EMI-prone lines |
| Ioff Max | 0.6 µA at TA = –40°C to +85°C - prevents back-current damage and system-level leakage when host VCC is off |
| Ci Typ | 1.5 pF - minimizes capacitive loading on high-impedance sources such as crystal oscillator outputs or GPIO wake-up lines |
| IOH/IOL | ±4 mA at VCC = 3 V - sufficient drive strength for fan-out-of-10 into standard CMOS loads without buffering |
Pinout & Package
X2SON-5 (0.80 mm × 0.80 mm, 0.4 mm pitch) package with wettable flank leads for automated optical inspection and solder-joint reliability in space-constrained PCBs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - N.C. | No internal connection | Must be left unconnected; no routing or thermal pad required |
| 2 - A | Input | Schmitt-trigger input accepting 0–3.6 V signals; immune to slow edges and noise up to 0.79 V hysteresis |
| 3 - GND | Ground reference | Primary return path for all internal logic and output current; requires low-inductance connection to system ground plane |
| 4 - Y | Output | Noninverting buffered output with rail-to-rail swing and ±4 mA drive capability at 3 V |
| 5 - VCC | Power supply | Single-supply input supporting 0.8–3.6 V; requires local 0.1 µF ceramic bypass capacitor placed ≤1 mm from pin |
Key Features
| Feature | Design Value |
|---|---|
| Schmitt-trigger input | Enables clean switching on slow or noisy signals (e.g., mechanical switch debouncing, RC time-constant circuits) |

| 3.6-V I/O tolerant | Allows direct interface with 3.3-V or 2.5-V drivers without level shifters, simplifying mixed-voltage board design |
| NanoStar™ X2SON packaging | 0.8 mm × 0.8 mm footprint with wettable flanks improves manufacturability and thermal performance in ultra-dense layouts |
| Ultra-low Ci (1.5 pF) | Reduces signal integrity degradation on high-frequency traces and preserves edge fidelity in point-to-point links |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schmitt-trigger buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC1G17DPW | Higher ICC (10 µA typ), wider VCC range (1.65–5.5 V), no Ioff support | Lacks partial-power-down protection; unsuitable for hot-swap or multi-rail sequencing | Select only if 5-V compatibility is required and system-level power sequencing is handled externally |
| NC7SZ17P5X | Smaller SC-70-5 package (1.25 × 2.0 mm), 3.6-V tolerant, but higher Cpd (9 pF) and slower tpd (7.5 ns @ 3.3 V) | Lower integration density and reduced speed margin for >100 MHz clock distribution | Prefer for cost-sensitive consumer designs where board area is less constrained than power budget |
Compared with SN74LVC1G17DPW and NC7SZ17P5X, SN74AUP1G17DPWR delivers the lowest static power (0.9 µA vs. 10 µA/1 µA), smallest footprint (0.8 × 0.8 mm), and unique Ioff protection - making it optimal for energy-critical, space-constrained, and multi-rail embedded systems.

FAQ
What is the maximum propagation delay of SN74AUP1G17DPWR at 3.3 V?
The maximum propagation delay (tpd) of SN74AUP1G17DPWR is 5.1 ns at VCC = 3.3 V, CL = 5 pF, and TA = –40°C to +85°C - verified per TI's SCES579J datasheet Section 6.6. This value ensures timing margin for sub-200 MHz digital control loops and meets setup/hold requirements for common microcontroller GPIO interfaces.
Does SN74AUP1G17DPWR support partial power-down operation?
Yes, SN74AUP1G17DPWR fully supports partial power-down via its Ioff circuitry. When VCC = 0 V, all inputs and outputs enter high-impedance state with leakage limited to 0.6 µA max over temperature - preventing back-current damage and enabling safe hot-plug operation in multi-rail systems.
What is the input hysteresis (ΔVT) of SN74AUP1G17DPWR at 3 V supply?
At VCC = 3 V, SN74AUP1G17DPWR provides a minimum hysteresis (ΔVT = VT+ − VT−) of 0.79 V over full temperature range, corresponding to ~26% of VCC. This ensures reliable noise rejection for signals with up to ±395 mV of superimposed interference without false triggering.
Can SN74AUP1G17DPWR interface with 5-V logic signals?
No, SN74AUP1G17DPWR inputs are rated for maximum 4.6 V absolute voltage but are not 5-V tolerant. Its 3.6-V I/O tolerance supports safe interfacing with 3.3-V and lower systems only. For 5-V signal domains, use SN74LVC1G17DPW or add external clamping.
What is the recommended bypass capacitor for SN74AUP1G17DPWR?
Texas Instruments recommends a 0.1 µF ceramic capacitor placed ≤1 mm from the VCC pin of SN74AUP1G17DPWR, with low-ESR/ESL construction and direct connection to the ground plane. This suppresses high-frequency supply noise and maintains stable operation during fast output transitions.
