Product details
Overview
SN74AUP2G17DSFR from Texas Instruments is a dual Schmitt-trigger buffer IC optimized for ultra-low-power operation across 0.8 V to 3.6 V supply rails. It features two independent non-inverting buffers with hysteresis (ΔVT = 0.79 V typical at 3 V), 5.1 ns max propagation delay at 3.3 V, 4.3 pF typical dynamic power capacitance, and Ioff support for partial-power-down mode - ideal for battery-powered sensor interfaces and portable logic level-shifting.
For engineers reviewing the SN74AUP2G17DSFR datasheet, SN74AUP2G17DSFR pinout, SN74AUP2G17DSFR application, or SN74AUP2G17DSFR equivalent, this page delivers verified package mapping (DSF 6-pin X2SON), confirmed Schmitt-trigger thresholds (VT+ = 2.29 V / VT– = 1.24 V at 3 V), real-world timing behavior under 15 pF load, and validated alternatives for low-voltage mixed-signal systems.
Technical Context
The SN74AUP2G17DSFR implements two independent non-inverting Schmitt-trigger buffers (Y = A) with asymmetric input thresholds enabling noise immunity in noisy digital environments. Its AUP-family architecture delivers sub-1 µA static current (ICC ≤ 0.9 mA max) and supports Ioff circuitry that disables outputs during power-down to prevent backflow current.
It operates across an extended VCC range (0.8 V–3.6 V), maintains signal integrity with <10% VCC overshoot/undershoot, and achieves 5.1 ns tpd at 3.3 V with 15 pF load - meeting requirements for point-to-point interconnects in space-constrained portable electronics.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 0.8 V to 3.6 V - enables direct interface 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, CL = 15 pF - ensures reliable timing in high-speed sensor data acquisition paths. |
| ΔVT (Hysteresis) | 0.79 V typical at 3 V - rejects up to ±395 mV of input noise without false triggering. |
| Cpd | 4.3 pF typical at 3.3 V - reduces dynamic power consumption in always-on wearable subsystems. |
| Ioff Support | Active at VCC = 0 V - prevents current leakage when host MCU is in deep sleep, extending battery life. |
| Input Capacitance | 1.5 pF typical - minimizes loading on high-impedance analog sensor outputs. |
Pinout & Package
SN74AUP2G17DSFR uses the DSF package: X2SON (6-pin, 1.05 mm × 1.05 mm, 0.4 mm max height), JEDEC MO-287 variation X2AAF, with wettable flanks and exposed thermal pad.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 1A (Buffer 1 Input) | Non-inverting Schmitt-trigger input for first buffer channel; accepts 0–3.6 V signals with hysteresis. |
| 2 | GND | Ground reference for both buffers and internal biasing; must be low-impedance for noise immunity. |
| 3 | 2A (Buffer 2 Input) | Non-inverting Schmitt-trigger input for second buffer channel; electrically isolated from Pin 1. |
| 4 | 2Y (Buffer 2 Output) | CMOS-compatible output driving up to ±4 mA at 3 V; supports Ioff when VCC = 0. |
| 5 | 1Y (Buffer 1 Output) | CMOS-compatible output with identical drive strength and Ioff capability as Pin 4. |
| 6 | VCC | Single-supply rail (0.8–3.6 V); powers both buffers and internal hysteresis circuitry. |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent Schmitt-trigger buffers | Enables simultaneous conditioning of two noisy digital signals (e.g., encoder quadrature A/B) without crosstalk. |
| Ultra-low ICC (≤0.9 mA max) | Extends runtime in coin-cell-powered IoT endpoints where average current budget is <1 µA. |
| 0.8 V minimum VCC operation | Allows direct integration with emerging sub-1 V microcontrollers and energy-harvesting PMICs. |
| ESD robustness (2000-V HBM) | Eliminates need for external ESD protection in handheld medical sensors and industrial field devices. |
| 1.5 pF input capacitance | Preserves bandwidth when buffering high-frequency analog comparator outputs or crystal oscillator signals. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual Schmitt-trigger buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC2G17DSFR | No hysteresis; standard CMOS input thresholds (VIH = 2.0 V, VIL = 0.8 V at 3.3 V). | Suitable only in low-noise environments; lacks noise immunity for mechanical switch or long-trace interfaces. | Select when cost sensitivity outweighs noise immunity needs and system layout guarantees clean signals. |
| TC7SZ17FU,EL | Higher ICC (1.5 µA typ vs. 0.9 µA max); narrower VCC range (1.65–5.5 V); no Ioff support. | Not suitable for partial-power-down systems or sub-1.65 V operation; requires external isolation for sleep modes. | Choose only for legacy 3.3 V/5 V designs where TI AUP family availability is constrained. |
Compared with SN74LVC2G17DSFR and TC7SZ17FU,EL, the SN74AUP2G17DSFR uniquely combines sub-1 µA static power, 0.8 V operation, and Ioff - making it the sole option for energy-harvesting nodes requiring guaranteed zero-backflow during multi-week sleep cycles.

FAQ
What is the maximum propagation delay of SN74AUP2G17DSFR at 1.8 V supply?
The SN74AUP2G17DSFR has a maximum propagation delay (tpd) of 7.2 ns at 1.8 V ± 0.15 V with 15 pF load, as specified in the Switching Characteristics table. This value is measured from input transition (VCC/2) to output transition (VCC/2) and reflects worst-case timing under recommended operating conditions - critical for synchronizing dual-channel sensor data in low-voltage systems.
Does SN74AUP2G17DSFR support mixed-voltage I/O when VCC = 2.5 V?
Yes. The SN74AUP2G17DSFR supports 3.6-V tolerant I/O regardless of VCC setting, meaning inputs can safely accept up to 3.6 V even when VCC = 2.5 V. This allows direct interfacing with higher-voltage peripherals without external level shifters - a key feature confirmed in the "3.6-V I/O Tolerant" specification under Features.
How does the hysteresis of SN74AUP2G17DSFR improve noise immunity in sensor applications?
The SN74AUP2G17DSFR provides 0.79 V typical hysteresis (ΔVT) at 3 V supply, creating distinct VT+ (2.29 V) and VT– (1.24 V) thresholds. This ensures signals with noise amplitudes below ±395 mV cannot cause multiple transitions - directly preventing false triggers from EMI-coupled noise in industrial sensor wiring or PCB traces longer than 5 cm.
Can SN74AUP2G17DSFR be used in partial-power-down mode with VCC = 0 V?
Yes. The SN74AUP2G17DSFR includes Ioff circuitry that actively disables outputs when VCC = 0 V, limiting Ioff current to ≤0.6 mA. This prevents damaging backflow current from live signal lines into a powered-down system - essential for maintaining safe operation in battery-backed real-time clocks or always-on wake-up controllers.
What is the thermal resistance (θJA) of the DSF package used by SN74AUP2G17DSFR?
The DSF (X2SON) package for SN74AUP2G17DSFR has a thermal resistance θJA of 300 °C/W, as documented in the Absolute Maximum Ratings table. This value assumes standard JEDEC JESD 51-7 test conditions and informs thermal design for continuous operation in sealed enclosures above 60 °C ambient.
