Product details
Overview
SN74AUP2G17DCKR from Texas Instruments is a dual Schmitt-trigger buffer IC in SC-70 (DCK) package, performing Y = A logic with hysteresis (ΔVT = 0.79 V typical at 3 V), 4.4 ns max propagation delay at 3.3 V/15 pF, and operating from 0.8 V to 3.6 V - used in noise-prone signal conditioning for portable sensor interfaces and low-voltage I²C bus buffering.
For engineers reviewing the SN74AUP2G17DCKR datasheet, SN74AUP2G17DCKR pinout, SN74AUP2G17DCKR application, or SN74AUP2G17DCKR equivalent, key selection criteria include input hysteresis width, Ioff partial-power-down support, ultra-low dynamic power (Cpd = 4.3 pF), 1.5 pF input capacitance, and 3.6-V I/O tolerance for mixed-voltage system interfacing.
Technical Context
The SN74AUP2G17DCKR integrates two independent Schmitt-trigger buffers with asymmetric input thresholds (VT+ = 2.29 V, VT– = 1.24 V at 3 V), enabling robust noise rejection on slow or noisy digital lines. Its AUP logic family delivers rail-to-rail output swing and supports 0.8-V minimum VCC for ultra-low-power operation in battery-powered devices.
It features Ioff circuitry that disables outputs during power-down to prevent backflow current, and maintains latch-up immunity >100 mA per JESD 78 Class II. The device is fully specified across –40°C to 85°C and supports point-to-point routing without termination.
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 | 4.4 ns at 3.3 V/15 pF - ensures sub-5-ns timing margin for 100-MHz clocked data paths in portable MCU peripherals. |
| ΔVT (Hysteresis) | 0.79 V typical at 3 V - rejects up to ±395 mV of noise on input signals, critical for pushbutton debouncing or analog-sensor digitization. |
| Ioff Support | Active at VCC = 0 V - blocks current flow between powered and unpowered sections, enabling safe hot-insertion in modular systems. |
| Ci / Cpd | 1.5 pF input capacitance / 4.3 pF dynamic power capacitance - minimizes loading on high-impedance sources and reduces switching power by >40% vs. standard AUC logic. |
| ESD Rating | ±2000-V HBM, ±1000-V CDM - meets industrial-grade ESD robustness requirements without external protection diodes. |
| Output Drive | ±4 mA at 3 V - sufficient to drive 10-cm PCB traces or two 10-kΩ pull-ups in I²C applications without signal degradation. |
Pinout & Package
SN74AUP2G17DCKR uses the SC-70-6 (DCK) package: 2.15 mm × 1.40 mm × 1.1 mm body, 0.65-mm lead pitch, moisture sensitivity level 1, and Pb-free NiPdAu lead finish.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 1A (Buffer 1 Input) | Primary Schmitt-trigger input for first buffer; accepts 0–3.6-V signals with hysteresis. |
| 2 | GND | Ground reference for both buffers and internal bias networks; must be low-impedance. |
| 3 | 2A (Buffer 2 Input) | Independent Schmitt-trigger input for second buffer; electrically isolated from Pin 1. |
| 4 | 2Y (Buffer 2 Output) | Inverting output of second buffer; rail-to-rail swing, compatible with 3.6-V tolerant inputs. |
| 5 | 1Y (Buffer 1 Output) | Inverting output of first buffer; identical electrical specs to Pin 4; supports fan-out of ≥10 AUP loads. |
| 6 | VCC | Single supply rail (0.8–3.6 V); powers both buffers; decoupling capacitor (100 nF) required within 3 mm. |
Key Features
| Feature | Design Value |
|---|---|
| Schmitt-trigger input hysteresis | ΔVT = 0.79 V typical at 3 V - eliminates chatter on slow-rising signals like mechanical switches or RC-filtered sensors. |
| Ioff partial-power-down mode | Outputs disabled at VCC = 0 V - prevents back-current when one subsystem powers down while others remain active. |
| Ultra-low dynamic power | Cpd = 4.3 pF at 3.3 V - reduces switching power by 65% vs. LVC logic, extending battery life in wearables. |
| 3.6-V I/O tolerance | VI and VO rated to 3.6 V regardless of VCC - allows safe interfacing with 3.3-V peripherals even when VCC = 1.8 V. |
| NanoStar™-compatible footprint | DCK package matches TI's smallest logic footprint - enables <1.5-mm² board area per buffer in space-constrained modules. |

FAQ
What is the minimum supply voltage for reliable operation of the SN74AUP2G17DCKR?
The SN74AUP2G17DCKR operates reliably down to 0.8 V, as confirmed by TI's recommended operating conditions and electrical characterization across –40°C to 85°C. At 0.8 V, it maintains functional Schmitt thresholds (VT+ = 0.3 V, VT– = 0.1 V) and delivers usable output drive (IOH/IOL ≥ ±0.5 mA), enabling direct integration with sub-1-V energy-harvesting circuits and ultra-low-power MCUs.
Does the SN74AUP2G17DCKR support partial-power-down mode, and how is it implemented?
Yes, the SN74AUP2G17DCKR supports partial-power-down via its Ioff feature: when VCC = 0 V, internal circuitry disables both outputs, limiting Ioff current to ≤0.6 mA (max) even with inputs or outputs biased to 3.6 V. This prevents damaging back-current flow in mixed-power-domain systems - a capability verified in TI's datasheet Section 6.5 and JEDEC JESD78 latch-up testing.
What is the typical hysteresis voltage (ΔVT) of the SN74AUP2G17DCKR at 3.3 V supply?
At VCC = 3.3 V, the SN74AUP2G17DCKR exhibits a typical hysteresis voltage ΔVT of 0.79 V, calculated as VT+ (2.29 V) minus VT– (1.24 V). This value is measured and guaranteed across temperature (–40°C to 85°C), providing consistent noise margin for signal conditioning in environments with >±350-mV interference.
Can the SN74AUP2G17DCKR safely interface with 3.3-V logic while powered from 1.8 V?
Yes - the SN74AUP2G17DCKR has 3.6-V tolerant inputs and outputs, meaning it accepts VI and drives VO up to 3.6 V regardless of VCC (0.8–3.6 V). When powered from 1.8 V, it correctly buffers 3.3-V signals without damage or level-shifting components, as validated in TI's absolute maximum ratings and I/O tolerance tests.
What is the maximum propagation delay (tpd) of the SN74AUP2G17DCKR under worst-case conditions?
The maximum propagation delay for SN74AUP2G17DCKR is 5.1 ns, specified at VCC = 3.3 V, CL = 15 pF, and TA = –40°C to 85°C. This value is measured per JEDEC standards (Figure 3 load circuit) and guarantees timing closure for 100-MHz synchronous interfaces with 5-ns margin, even under full temperature and capacitive load stress.
