Product details
Overview
SN74AUP1G07DCKR from Texas Instruments is a single non-inverting buffer with open-drain output, designed for level translation and wired-OR logic in ultra-low-power systems. It operates across 0.8 V to 3.6 V supply, delivers 3.3 ns max propagation delay at 3.3 V, consumes ≤0.9 µA ICC, and supports Ioff for live insertion-used in portable medical sensors and battery-powered interface circuits.
For engineers reviewing the SN74AUP1G07DCKR datasheet, SN74AUP1G07DCKR pinout, SN74AUP1G07DCKR application, or SN74AUP1G07DCKR equivalent, key selection criteria include its 0.8–3.6 V VCC range, open-drain output drive capability up to 20 mA, input hysteresis (250 mV typ), 1.5 pF input capacitance, and SC70-5 package compatibility with space-constrained PCB layouts.
Technical Context
The SN74AUP1G07DCKR implements a CMOS-based single-buffer architecture with open-drain output, enabling active-low wired-OR and active-high wired-AND bus configurations. Its Ioff circuitry disables outputs when VCC = 0 V, preventing back-drive current during partial power-down.
Input hysteresis (250 mV typ at 3.3 V) improves noise immunity against slow or noisy transitions, while low dynamic power (Cpd = 1 pF typ at 3.3 V) and ultra-low static current (ICC ≤ 0.9 µA) make it suitable for always-on sensor interfaces and energy-harvesting subsystems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 0.8 V to 3.6 V - enables direct interfacing between sub-1V microcontrollers and 3.3V peripherals without external level shifters. |
| tpd Max | 3.3 ns at 3.3 V, CL = 5 pF - ensures timing-critical point-to-point signal buffering with minimal latency in high-speed digital control paths. |
| ICC Max | 0.9 µA at 3.6 V - supports multi-year battery life in IoT endpoint nodes and wearable health monitors. |
| IOL Max | 20 mA at VCC ≥ 2.3 V - drives standard LED indicators, pull-up networks, or I²C bus lines without external FETs. |
| Input Hysteresis | 250 mV typical at 3.3 V - rejects EMI-induced glitches on long traces or unshielded sensor inputs in industrial environments. |
| Input Capacitance | 1.5 pF typical - minimizes loading on high-impedance analog sensor outputs or crystal oscillator feedback paths. |
| Ioff Support | Active at VCC = 0 V - allows hot-plug insertion into powered-backplane systems without damaging upstream drivers or downstream loads. |
Pinout & Package
SN74AUP1G07DCKR uses the SC70-5 (DCK) package: 2.00 mm × 1.25 mm body, 0.65 mm height, 0.65 mm lead pitch, and wettable flank leads for automated optical inspection.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | No Connection (NC) | Internally unconnected; must be left floating or tied to GND per layout best practice-no electrical function. |
| 2 | Input A | CMOS-compatible digital input with hysteresis; accepts voltages up to 3.6 V regardless of VCC (I/O tolerant). |
| 3 | GND | Primary ground reference for internal logic and output stage; requires low-inductance connection to system ground plane. |
| 4 | Output Y | Open-drain NMOS output-requires external pull-up to define high state; sinks up to 20 mA when active low. |
| 5 | VCC | Single power supply input; bypass capacitor (0.1 µF ceramic) must be placed within 2 mm for stable operation. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low ICC | ≤0.9 µA max - reduces quiescent current in always-on wake-up circuits, extending shelf life of sealed medical devices. |
| Open-drain output | Supports wired-OR logic and bidirectional bus arbitration - eliminates need for external diodes in shared interrupt lines. |
| Ioff protection | Enables safe operation during partial power-down - prevents reverse current flow when VCC is off but I/O pins remain biased. |
| Input hysteresis | 250 mV typical - stabilizes switching thresholds against noise on slow-rising signals from thermistors or potentiometers. |
| 0.8–3.6 V operation | Matches voltage rails of modern sub-1V SoCs and legacy 3.3V peripherals - simplifies mixed-voltage board design. |
Applications
| Barcode Scanner | Blood Pressure Monitor |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC1G07DCKR | Higher ICC (10 µA typ), wider VCC (1.65–5.5 V), no Ioff, no hysteresis | Not suitable for partial-power-down or noisy sensor inputs; better for general-purpose 3.3/5V logic. | Select only if operating above 1.65 V and Ioff/hysteresis are unnecessary. |
| TC7SZ07FU,EL | Lower VCC min (0.9 V), similar ICC (0.9 µA), no Ioff, smaller USON-5 (1.2 × 1.2 mm) | Lacks live-insertion support; limited thermal performance (RθJA = 340°C/W vs. 314°C/W for DCK). | Prefer for ultra-dense layouts where Ioff is not required and ambient temperature stays below 65°C. |
Compared with SN74LVC1G07DCKR and TC7SZ07FU,EL, SN74AUP1G07DCKR uniquely combines sub-1V operation, Ioff, and input hysteresis-making it the only choice for battery-powered, hot-pluggable, noise-immune sensor interface designs requiring <1 µA quiescent current.

FAQ
What is the maximum output sink current for SN74AUP1G07DCKR?
The SN74AUP1G07DCKR supports a maximum output sink current (IOL) of 20 mA when VCC ≥ 2.3 V. At lower supply voltages, the rated current decreases-for example, 1.9 mA at 1.65 V. This specification ensures reliable driving of LEDs, pull-up resistors, and I²C bus lines without external amplification. Always verify load conditions against the Electrical Characteristics table in the official datasheet SCES591J.
Does SN74AUP1G07DCKR support level translation between different voltage domains?
Yes, SN74AUP1G07DCKR supports bidirectional level translation due to its 3.6-V I/O tolerance and wide 0.8–3.6 V VCC range. An input driven to 3.3 V remains valid even when VCC = 1.2 V, enabling down-translation from higher-voltage peripherals to sub-1V microcontrollers. The open-drain output further simplifies up-translation via external pull-up to the target domain voltage.
Can SN74AUP1G07DCKR be used in partial-power-down systems?
Yes, SN74AUP1G07DCKR includes Ioff circuitry that disables outputs when VCC = 0 V, preventing damaging back-current flow from live I/O pins into a powered-down supply rail. This feature enables safe live insertion into backplanes and hot-swap capability in modular sensor systems-confirmed in Section 9.3 of the SCES591J datasheet.
What is the purpose of the NC pin (Pin 1) on SN74AUP1G07DCKR?
Pin 1 of SN74AUP1G07DCKR is a No-Connection (NC) terminal with no internal bond wire or silicon connection. It must be left unconnected or tied to GND per TI layout guidelines-never driven or pulled high. This pin exists for mechanical symmetry and package compatibility; routing traces to it provides no functional benefit and may risk solder bridging in fine-pitch assembly.
How does input hysteresis improve noise immunity in SN74AUP1G07DCKR?
SN74AUP1G07DCKR features 250 mV typical input hysteresis at 3.3 V, meaning the VIH threshold is ~250 mV higher than VIL. This creates a built-in noise margin that prevents oscillation on slowly transitioning or EMI-contaminated signals-such as those from thermistors, potentiometers, or long PCB traces. It eliminates the need for external RC filtering in many sensor interface applications.
