Product details
Overview
SN74AUP2G17DRYR from Texas Instruments is a dual Schmitt-trigger buffer IC in a 6-pin SON (DRY) package, operating from 0.8 V to 3.6 V with 5.4 ns max propagation delay at 3.3 V and 15 pF load. It delivers low static current (0.9 mA max), 4.3 pF typical dynamic power capacitance, and supports partial-power-down via Ioff. Used in noise-prone signal conditioning for portable battery-powered interfaces.
For engineers reviewing the SN74AUP2G17DRYR datasheet, SN74AUP2G17DRYR pinout, SN74AUP2G17DRYR application, or SN74AUP2G17DRYR equivalent, key selection criteria include hysteresis thresholds (VT+ = 2.29 V / VT– = 1.24 V at 3 V), input capacitance (1.5 pF), Ioff-enabled isolation, and 0.6 mm max package height for space-constrained PCBs.
Technical Context
The SN74AUP2G17DRYR implements two independent non-inverting buffers with Schmitt-trigger inputs, providing hysteresis (ΔVT up to 1.31 V at 3 V) to reject noise on slow or noisy signals. Its AUP logic family ensures ultra-low power across the full 0.8–3.6 V supply range, with ICC ≤ 0.9 mA and Cpd = 4.3 pF at 3.3 V.
Designed for point-to-point routing, it features Ioff circuitry that disables outputs during power-down to prevent backflow current, and supports mixed-mode I/O with 3.6-V tolerant inputs. Signal integrity is enhanced by <10% VCC overshoot/undershoot and latch-up immunity exceeding 100 mA per JESD 78 Class II.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 0.8 V to 3.6 V - Enables direct interface with sub-1V logic and compatibility with 3.3-V systems without level shifters. |
| Max Propagation Delay | 5.4 ns at 3.3 V, CL = 15 pF - Supports clean signal transmission up to ~100 MHz in short trace point-to-point links. |
| Hysteresis (ΔVT) | 1.31 V at VCC = 3 V - Rejects >1.3 V peak-to-peak noise on input signals, critical for pushbutton debouncing or sensor interfacing. |
| Input Capacitance (Ci) | 1.5 pF typical - Minimizes loading on high-impedance sources like crystal oscillators or analog sensors. |
| Ioff Current | 0.6 µA max at 0 V - Ensures safe isolation when one rail is powered down in multi-voltage systems (e.g., USB suspend). |
| Output Drive | ±4 mA at VCC = 3 V - Sufficient to drive 50 Ω traces or small capacitive loads without external buffering. |
| ESD Rating | 2000-V HBM, 1000-V CDM - Meets industrial-grade robustness requirements without added protection components. |
Pinout & Package
SN74AUP2G17DRYR uses a 6-pin SON (Small Outline No-Lead) package, DRY variant, measuring 1.45 mm × 1.0 mm × 0.6 mm max height with wettable flanks and exposed thermal pad. Pin 1 is marked by a corner chamfer or solder mask opening.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 1A (Buffer 1 Input) | Schmitt-trigger input for first buffer; accepts 0–3.6 V with hysteresis; must be tied to VCC or GND if unused. |
| 2 | GND | Ground reference for both buffers and internal logic; connects to exposed thermal pad for thermal dissipation. |
| 3 | 1Y (Buffer 1 Output) | Non-inverting buffered output; drives CMOS loads up to ±4 mA; supports Ioff isolation. |
| 4 | 2A (Buffer 2 Input) | Independent Schmitt-trigger input; electrically isolated from 1A; same threshold specs as Pin 1. |
| 5 | 2Y (Buffer 2 Output) | Second non-inverting output; identical drive strength and timing to Pin 3; shares same VCC/GND rails. |
| 6 | VCC | Single supply rail (0.8–3.6 V); powers both buffers; decoupling capacitor (0.1 µF) required near this pin. |
Key Features
| Feature | Design Value |
|---|---|
| Dual Schmitt-trigger buffers | Two independent channels with separate VT+ (2.29 V) and VT– (1.24 V) thresholds at 3 V - enables reliable signal restoration in noisy environments. |
| Ultra-low dynamic power | 4.3 pF typical power dissipation capacitance at 3.3 V - reduces switching current and system-level EMI in battery-operated devices. |
| Ioff partial-power-down | 0.6 µA max off-state current with VCC = 0 V - prevents backfeed and allows hot insertion in multi-rail systems without sequencing. |
| Wide VCC range | Operates from 0.8 V (ultra-low-power MCU core) to 3.6 V (I/O domain) - eliminates need for voltage translators in mixed-supply designs. |
| Low input capacitance | 1.5 pF typical - preserves rise/fall times when driving long traces or high-frequency clocks without signal degradation. |
Applications
| Pushbutton Debouncing | Sensor Signal Conditioning |
|---|---|
Use Scenario: Mechanical switch inputs in handheld medical devices generate bounce lasting 5–20 ms with high dV/dt noise.

Use Value: Prevents false triggers and ADC conversion errors; maintains signal fidelity without adding op-amp stages or layout shielding. |
| Low-Power Clock Buffering | USB/UART Level Translation |
Use Scenario: 32.768 kHz crystal oscillator output requires distribution to RTC and sleep controller in wearables. IC Role / Device Role / Timing Role: SN74AUP2G17DRYR provides low-capacitance (1.5 pF), low-delay (5.4 ns) fanout with rail-to-rail swing. Use Value: Preserves clock edge integrity over 20 mm PCB traces; draws only 0.9 mA total ICC, extending battery life beyond 1 year. | Use Scenario: Microcontroller running at 1.8 V communicates with 3.3 V UART transceiver; bidirectional level shifting needed. IC Role / Device Role / Timing Role: SN74AUP2G17DRYR serves as unidirectional level translator using its 3.6-V tolerant inputs and 1.8 V–3.3 V compatible outputs. Use Value: Enables simple, passive translation without direction control lines or dedicated level shifter ICs; supports 10 Mbps UART rates. |
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 | Higher ICC (10 µA typ vs. 0.9 mA max), faster tpd (3.7 ns), but no Ioff and narrower VCC (1.65–5.5 V). | Not suitable for partial-power-down or sub-1.65 V operation; better for speed-critical 3.3/5 V systems. | Choose SN74LVC2G17DSFR only if speed >4 ns and Ioff is unnecessary; avoid for battery-powered or multi-rail designs. |
| SN74AUP2G34DRYR | Same AUP family, identical package and VCC range, but non-Schmitt (CMOS) inputs; Ci = 2.5 pF, Cpd = 5.2 pF. | Lacks hysteresis - unsuitable for noisy or slow-edge signals; used where clean digital signals require minimal power. | Select SN74AUP2G34DRYR only for known-clean inputs (e.g., FPGA outputs); use SN74AUP2G17DRYR when noise immunity is required. |
Compared with SN74LVC2G17DSFR and SN74AUP2G34DRYR, the SN74AUP2G17DRYR uniquely combines sub-1V operation, Ioff isolation, and Schmitt-trigger noise rejection - making it the only choice for ultra-low-power, mixed-rail, noise-prone embedded sensing nodes.

FAQ
What is the maximum operating temperature range for the SN74AUP2G17DRYR?
The SN74AUP2G17DRYR is rated for operation from –40°C to +85°C ambient temperature, validated across its full 0.8 V to 3.6 V supply range. This industrial-grade thermal specification ensures reliability in outdoor sensor housings, automotive cabin modules, and portable medical equipment without derating.
Does the SN74AUP2G17DRYR support true bidirectional signal translation?
No, the SN74AUP2G17DRYR is a unidirectional non-inverting buffer with Schmitt-trigger inputs and standard CMOS outputs. It does not support automatic direction sensing or bus arbitration. For bidirectional level translation, discrete MOSFET-based circuits or dedicated translators like TXS0102 are required instead of SN74AUP2G17DRYR.
Can unused inputs on the SN74AUP2G17DRYR be left floating?
No - all unused inputs of the SN74AUP2G17DRYR must be tied to either VCC or GND to prevent undefined logic states, increased ICC, and potential oscillation. Floating Schmitt inputs may drift between VT+ and VT– thresholds, causing excessive current draw and noise coupling into adjacent channels on the same SN74AUP2G17DRYR die.
What is the recommended PCB land pattern for the SN74AUP2G17DRYR DRY package?
The SN74AUP2G17DRYR DRY package requires a non-solder-mask-defined (NSMD) land pattern with 0.25 mm pad width, 0.35 mm pad length, 0.4 mm pitch, and a centered 0.8 mm × 0.6 mm thermal pad with 5 × 0.3 mm solder paste apertures. TI's SLUA271 application report specifies this layout to ensure coplanarity and thermal performance.
How does the Ioff feature of the SN74AUP2G17DRYR protect downstream circuitry?
The Ioff feature in the SN74AUP2G17DRYR disables output drivers when VCC = 0 V, limiting leakage current to ≤0.6 µA per pin. This prevents backflow current from live buses (e.g., 3.3 V UART lines) into a powered-down microcontroller domain, avoiding latch-up, data corruption, or damage - a critical safeguard in modular systems with hot-swap capability.
