Product details
Overview
SN74AUP1G17DRYR 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, draws ≤0.9 µA static current, and supports partial power-down via Ioff. It is used in point-to-point signal integrity enhancement on battery-powered PCBs.
For engineers reviewing the SN74AUP1G17DRYR datasheet, SN74AUP1G17DRYR pinout, SN74AUP1G17DRYR application, or SN74AUP1G17DRYR equivalent, key selection criteria include its 1.5 pF input capacitance, 3.6-V I/O tolerance for mixed-voltage interfacing, Schmitt-trigger hysteresis (0.07–1.31 V), and SON-6 package compatibility with high-density layouts.
Technical Context
The SN74AUP1G17DRYR implements a non-inverting 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. Its balanced CMOS push-pull output drives ±4 mA at 3.0 V while maintaining rail-to-rail VOH/VOL performance under load.
It features Ioff circuitry enabling safe partial power-down: when VCC = 0 V, all I/O pins enter high-impedance state with ≤0.6 µA leakage over –40°C to +85°C. Input overvoltage tolerance up to 4.6 V allows interfacing with higher-voltage signals without level shifters.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 0.8 V to 3.6 V - enables direct integration into multi-rail battery-powered systems (e.g., 1.2 V, 1.8 V, 3.3 V domains) |
| tpd Max | 5.1 ns at 3.3 V - ensures timing-critical signal buffering with minimal latency in high-speed digital interfaces |
| ICC Max | 0.9 µA - extends battery life in always-on sensor nodes and wearable devices |
| Input Capacitance | 1.5 pF - minimizes loading on high-impedance sources (e.g., crystal oscillators, analog comparators) |
| Hysteresis ΔVT | 0.79 V typical at 3.0 V VCC - rejects noise up to ~800 mV peak-to-peak on slow-rising control lines |
| Ioff Leakage | 0.6 µA max at –40°C to +85°C - prevents back-current damage during hot-plug or power sequencing |
| IO Drive | ±4 mA at 3.0 V - sufficient to drive multiple CMOS inputs or short PCB traces without external buffers |
Pinout & Package
SN74AUP1G17DRYR uses a 6-pin SON (Small Outline No-Lead) package measuring 1.00 mm × 1.45 mm with wettable flanks, optimized for automated optical inspection and high-density routing.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | No Connection (N.C.) | Internally unconnected; must be left floating or tied to GND per layout best practice |
| 2 | Input A | Schmitt-trigger input accepting 0–3.6 V signals; immune to slow edges and noise |
| 3 | GND | Digital ground reference; requires low-inductance connection to system ground plane |
| 4 | Output Y | Non-inverting buffered output with rail-to-rail swing and ±4 mA drive capability |
| 5 | VCC | Power supply input; requires local 0.1 µF ceramic bypass capacitor placed ≤2 mm from pin |
| 6 | No Connection (N.C.) | Internally unconnected; no external connection required |
Key Features
| Feature | Design Value |
|---|---|
| Schmitt-trigger input | Enables reliable switching on noisy or slowly transitioning signals (e.g., reset lines, mechanical switch debouncing) |
| Ioff partial power-down | Prevents current backflow when VCC = 0 V, supporting hot-swap and power-gating architectures |
| 3.6-V I/O tolerant | Allows direct interface with 3.3-V or 2.5-V peripherals without level-shifting circuitry |
| Low dynamic power (Cpd = 4.4 pF) | Reduces switching noise and EMI in sensitive RF or audio subsystems |
| NanoStar™ packaging | Die-as-package construction minimizes parasitic inductance and improves thermal resistance (RθJA = 347.8°C/W) |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schmitt-trigger buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC1G17DBVR | Wider VCC range (1.65–5.5 V); higher ICC (10 µA typ); no Ioff support | Requires external power sequencing control; unsuitable for partial-power-down systems | Choose when interfacing legacy 5-V logic or when higher drive strength (±24 mA) is needed |
| NC7SZ17P5X | Smaller SC-70-5 package (1.25 × 2.00 mm); identical VCC range; slightly higher Cpd (5.5 pF) | Larger footprint than DRYR's 1.00 × 1.45 mm SON; less optimal for ultra-dense wearables | Choose when SC-70 placement tooling is standardized and thermal performance is secondary |
Compared with SN74LVC1G17DBVR and NC7SZ17P5X, SN74AUP1G17DRYR uniquely combines sub-µA static current, Ioff-enabled power gating, and the smallest footprint among TI-qualified Schmitt buffers-making it optimal for space-constrained, battery-sensitive designs where power sequencing and layout density are critical.

FAQ
What is the maximum operating temperature for SN74AUP1G17DRYR?
The SN74AUP1G17DRYR is fully specified for operation from –40°C to +85°C ambient temperature. Its thermal metrics-including RθJA = 347.8°C/W for the SON-6 package-ensure reliable performance within this range when proper PCB copper pour and bypassing are implemented per TI layout guidelines.
Does SN74AUP1G17DRYR support true bidirectional signal flow?
No, SN74AUP1G17DRYR is a unidirectional non-inverting buffer with fixed input (pin 2) and output (pin 4). It does not support bidirectional data transfer or bus arbitration. For bidirectional applications, discrete direction-control logic or dedicated transceivers like SN74LVC245A are required.
Can SN74AUP1G17DRYR be used with a 0.9-V supply?
Yes, SN74AUP1G17DRYR is fully characterized down to 0.8 V VCC. At 0.9 V, it maintains functional Schmitt-trigger behavior (VT+ ≈ 0.35 V, VT– ≈ 0.15 V) and delivers usable output drive (≥20 µA), making it suitable for emerging sub-1-V ultra-low-power microcontrollers and energy-harvesting systems.
How does the Ioff feature protect SN74AUP1G17DRYR during power sequencing?
When VCC = 0 V, the Ioff circuitry places both input (A) and output (Y) pins in high-impedance state, limiting leakage to ≤0.6 µA. This prevents back-current from live signal lines into a powered-down domain-protecting SN74AUP1G17DRYR and upstream/downstream components during staggered power-up sequences.
Is SN74AUP1G17DRYR pin-compatible with other AUP-series single-gate buffers?
SN74AUP1G17DRYR shares the same 6-pin SON footprint with SN74AUP1G04DRYR and SN74AUP1G08DRYR, but pin functions differ: SN74AUP1G04 is an inverter (A→Y̅), SN74AUP1G08 is an AND gate (A·B→Y), and SN74AUP1G17DRYR is a non-inverting Schmitt buffer (A→Y). Direct substitution requires logic and timing validation.
