Product details
Overview
SN74AUP1G17MDCKREP from Texas Instruments is a low-power single Schmitt-trigger buffer IC in SC-70 (DCK) 5-pin package, operating from 0.8 V to 3.6 V supply, with 5.1 ns max propagation delay at 3.3 V, 1.5 pF input capacitance, and Ioff support for partial-power-down mode - used in noise-prone signal conditioning paths in battery-powered portable electronics.
For engineers reviewing the SN74AUP1G17MDCKREP datasheet, SN74AUP1G17MDCKREP pinout, SN74AUP1G17MDCKREP application, or SN74AUP1G17MDCKREP equivalent, key selection criteria include hysteresis voltage (∆VT = 0.18–1.31 V), rail-to-rail input tolerance, 3.6-V I/O tolerance for mixed-voltage interfacing, and ultra-low ICC = 0.9 µA max static current.
Technical Context
This device implements a noninverting Schmitt-trigger buffer with asymmetric hysteresis thresholds (VT+ and VT−) enabling robust noise immunity on slow-rising or noisy digital inputs. It supports full Ioff functionality, disabling outputs and blocking backflow current when VCC = 0 V.
The AUP family targets ultra-low power across wide VCC range (0.8–3.6 V), delivering <4.4 pF dynamic power dissipation capacitance and <10% overshoot/undershoot relative to VCC - critical for signal integrity in high-density, low-voltage PCB layouts.
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 - ensures timing-critical signal buffering with minimal delay penalty in high-speed control paths. |
| ∆VT (Hysteresis) | 0.18 V min to 1.31 V max - provides configurable noise margin against EMI and crosstalk in industrial sensor interfaces. |
| Ioff Current | <5.0 µA at 0 V - guarantees safe isolation during hot-insertion or partial power-down of subsystems. |
| CI / Cpd | 1.5 pF input capacitance / 4.4 pF typical power dissipation capacitance - minimizes loading on driving gates and reduces dynamic power. |
| IOH/IOL | ±4 mA output drive at 3 V - sufficient to drive multiple CMOS loads or short PCB traces without external buffers. |
| ESD Rating | 2000-V HBM, 200-V MM, 1000-V CDM - meets industrial-grade robustness requirements without external protection. |
Pinout & Package
SC-70 (DCK) 5-pin plastic surface-mount package, 1.1 mm max height, 2.02 mm × 1.25 mm body size, lead-free NiPdAu finish, MSL Level-1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (NC) | No-connect terminal | Internally unconnected; must be left floating or tied to GND per layout best practice - no electrical function. |
| 2 (A) | Input | Schmitt-trigger input with hysteresis; accepts 0–3.6 V signals regardless of VCC, enabling mixed-voltage sampling. |
| 3 (GND) | Ground reference | Primary return path for all internal circuitry and output current; requires low-inductance connection to system ground plane. |
| 4 (Y) | Output | Noninverting buffered output with rail-to-rail swing (VOL ≤ 0.475 V, VOH ≥ 2.55 V at 3 V); drives capacitive loads up to 50 pF. |
| 5 (VCC) | Supply voltage | Power input for core logic and output stage; bypass capacitor (0.1 µF) required within 2 mm for stable operation. |
Key Features
| Feature | Design Value |
|---|---|
| Schmitt-trigger input | Enables reliable switching on slow or noisy edges (e.g., mechanical switch debouncing or sensor output conditioning) without external RC networks. |
| Ioff partial-power-down | Prevents back-current flow when VCC is off - essential for hot-swap capability and multi-rail system power sequencing. |
| 3.6-V I/O tolerance | Allows direct connection to 3.3-V or lower-VCC systems while powered from 1.8-V or 1.2-V rails - eliminates need for discrete level translators. |
| Ultra-low ICC | 0.9 µA max static current extends battery life in always-on monitoring circuits such as IoT endpoint wake-up detectors. |
| Low-noise output | Overshoot/undershoot limited to <10% of VCC - reduces EMI and avoids false triggering in adjacent high-impedance analog or RF sections. |
Applications
| Industrial Sensor Interface | Portable Device Power Sequencing |
|---|---|
|
Use Scenario: Conditioning slow-rising analog sensor outputs (e.g., thermistor-based temperature monitors) before ADC sampling in factory automation nodes.

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), narrower VCC range (1.65–5.5 V), no Ioff, 3.3-V only optimized. | Lacks partial-power-down support; unsuitable for hot-swap or multi-rail isolation use cases. | Choose when cost is primary constraint and system operates exclusively at 3.3 V with no power sequencing needs. |
| MC74VHC1G17DTT1G | Wider VCC (2–5.5 V), higher tpd (7.5 ns min), no Ioff, 5-V tolerant but not 3.6-V I/O tolerant at low VCC. | Not compatible with sub-2-V logic domains; cannot replace SN74AUP1G17MDCKREP in 1.2-V or 1.8-V systems. | Select only for legacy 5-V or 3.3-V-only designs requiring higher drive strength (8 mA) and higher ambient temperature rating. |

FAQ
What is the minimum operating voltage for SN74AUP1G17MDCKREP?
The SN74AUP1G17MDCKREP operates down to 0.8 V supply voltage, enabling direct integration into ultra-low-voltage subsystems such as energy-harvesting sensors or sub-1-V microcontroller peripherals. This specification is verified across the full –55°C to 125°C temperature range and is not a typical-only value.
Does SN74AUP1G17MDCKREP support partial-power-down mode?
Yes, SN74AUP1G17MDCKREP includes Ioff circuitry that disables outputs and limits input/output leakage to <5.0 µA when VCC = 0 V. This feature prevents damaging back-current flow during hot-swap events or staged power-up sequences in multi-rail systems.
What is the hysteresis voltage (∆VT) of SN74AUP1G17MDCKREP at 1.8 V supply?
At VCC = 1.8 V, the SN74AUP1G17MDCKREP exhibits ∆VT = 0.27 V (min) to 0.66 V (max), calculated as the difference between VT+ (0.91–1.29 V) and VT− (0.47–0.84 V). This hysteresis ensures reliable switching in presence of up to ±330 mV of input noise.
Can SN74AUP1G17MDCKREP interface between a 1.2-V microcontroller and a 3.3-V peripheral?
Yes - SN74AUP1G17MDCKREP accepts input voltages up to 3.6 V independent of VCC, and its 3.6-V I/O tolerance allows safe connection to 3.3-V peripherals even when powered from 1.2 V. No external level shifter is required for this mixed-voltage interface.
What package type and dimensions does SN74AUP1G17MDCKREP use?
SN74AUP1G17MDCKREP uses the SC-70 (DCK) 5-pin package: 2.02 mm × 1.25 mm body size, 1.1 mm maximum height, 0.65 mm pin pitch. Pin 1 identifier is marked with a dot; the package is RoHS-compliant with NiPdAu lead finish and MSL Level-1 rating.
