Product details
Overview
SN74AUP1G07DCKRG4 from Texas Instruments is a single non-inverting buffer with open-drain output, designed for low-voltage logic translation and level-shifting in battery-powered systems. It operates across 0.8 V to 3.6 V supply, delivers 3.3 ns max propagation delay at 3.3 V, supports Ioff for live insertion, and features 1.5 pF typical input capacitance - enabling use in portable medical sensors and USB peripheral interfaces.
For engineers reviewing the SN74AUP1G07DCKRG4 datasheet, SN74AUP1G07DCKRG4 pinout, SN74AUP1G07DCKRG4 application, or SN74AUP1G07DCKRG4 equivalent, key selection criteria include its ultra-low ICC (0.9 µA max), open-drain compatibility with wired-AND bus topologies, 3.6-V I/O tolerance for mixed-voltage interfacing, and SC70-5 package footprint (2.0 mm × 1.25 mm) for space-constrained PCB layouts.
Technical Context
The SN74AUP1G07DCKRG4 implements a CMOS-based single-buffer architecture with no internal pull-up; output Y requires external pull-up for logic high assertion. Its Ioff circuitry actively disables outputs when VCC = 0 V, preventing back-drive current during partial power-down - critical for hot-swap subsystems in embedded controllers.
Input hysteresis (250 mV typ at 3.3 V) improves noise immunity against slow-rising signals, while low dynamic power (Cpd = 1 pF typ at 3.3 V) and sub-1-µA quiescent current enable operation in always-on sensor nodes without compromising battery life.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 0.8 V to 3.6 V - enables direct interface with 0.8-V microcontrollers and 3.3-V peripherals without level-shifters. |
| Max Propagation Delay | 3.3 ns at 3.3 V, CL = 5 pF - supports >100-MHz signal routing in timing-critical I²C or SMBus pull-up configurations. |
| Quiescent Current (ICC) | 0.9 µA maximum - reduces standby power in battery-operated ECG monitors and wearable biometric devices. |
| Ioff Support | Active at VCC = 0 V - allows safe live insertion into powered-backplane systems without damaging upstream drivers. |
| Input Capacitance (Ci) | 1.5 pF typical - minimizes loading on high-impedance sensor outputs like piezoelectric pressure transducers. |
| Output Drive (IOL) | 4 mA at 3 V - sufficient to drive 10-kΩ pull-up resistors in 3.3-V I²C buses with standard timing margins. |
| ESD Rating | 2000-V HBM - meets industrial-grade robustness requirements for field-deployable HVAC control modules. |
Pinout & Package
SN74AUP1G07DCKRG4 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 1 is marked by a dot; Pin 3 is GND; Pin 5 is VCC.
| 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 0–3.6 V signals regardless of VCC, enabling voltage translation. |
| 3 | GND | Primary ground reference for all internal circuitry and I/O - requires low-inductance connection to system ground plane. |
| 4 | Output Y | Open-drain NMOS output - requires external pull-up; sinks up to 20 mA; cannot source current. |
| 5 | VCC | Core supply pin - bypass with 0.1 µF ceramic capacitor placed within 2 mm of pin for stable low-noise operation. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low static power | ICC ≤ 0.9 µA max across full VCC range - extends battery life in portable blood pressure monitors beyond 12 months. |
| Open-drain output | Enables wired-AND bus sharing with multiple SN74AUP1G07DCKRG4 devices - eliminates need for external logic gates in multi-sensor alarm lines. |
| 3.6-V I/O tolerance | Accepts inputs up to 3.6 V even when VCC = 0.8 V - simplifies interface between 3.3-V UART peripherals and 0.9-V ultra-low-power MCUs. |
| Ioff protection | Blocks current flow from I/O pins to VCC when powered down - prevents back-powering of failed power rails in server motherboard management controllers. |
| Input hysteresis | Vhys = 250 mV typ at 3.3 V - rejects EMI-induced glitches on long traces in CPAP machine airflow sensor lines. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar buffer/level-shifter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC1G07DCKR | Higher ICC (10 µA typ), wider VCC range (1.65–5.5 V), no Ioff support | Suitable for 5-V legacy systems but unsafe for live-insertion or zero-VCC partial power-down | Choose only if 5-V compatibility is required and Ioff is not needed. |
| 74AHC1G07SE-7 | Same open-drain function, 2.0–5.5 V VCC, 3.5 ns tpd at 5 V, no hysteresis | Lacks input hysteresis and Ioff - vulnerable to noise on long sensor traces and back-drive during power sequencing | Select only for cost-sensitive 5-V-only designs where noise immunity and hot-swap are non-critical. |

FAQ
What is the maximum output sink current for SN74AUP1G07DCKRG4?
The SN74AUP1G07DCKRG4 supports a continuous output sink current of ±20 mA per output pin. At VCC = 3 V and IOL = 4 mA, the output voltage (VOL) remains ≤0.45 V, ensuring reliable low-state assertion in 3.3-V I²C or SMBus applications. Exceeding 20 mA risks exceeding absolute maximum ratings and may degrade long-term reliability.
Does SN74AUP1G07DCKRG4 require external pull-up resistors on its output?
Yes, SN74AUP1G07DCKRG4 has an open-drain output (Pin 4, Y) and cannot source current. An external pull-up resistor - typically 2.2 kΩ to 10 kΩ connected to a valid logic-high voltage - is mandatory to establish HIGH-level logic states. The value must be selected based on bus capacitance and rise-time requirements per I²C or custom protocol specifications.
Can SN74AUP1G07DCKRG4 operate with VCC = 0 V while signals are present on input or output pins?
Yes, SN74AUP1G07DCKRG4 features Ioff circuitry that disables the output stage and isolates input/output pins when VCC = 0 V. This allows safe live insertion into powered systems and prevents damaging back-current flow - a requirement confirmed in TI's datasheet Section 9.1 and Electrical Characteristics Table 7.5 (Ioff ≤ 0.6 µA).
What is the input hysteresis voltage of SN74AUP1G07DCKRG4 and why does it matter?
The SN74AUP1G07DCKRG4 provides 250 mV typical input hysteresis (Vhys) at 3.3 V supply. This built-in Schmitt-trigger behavior prevents oscillation on slow-rising or noisy inputs - such as those from thermistor-based temperature sensors or long PCB traces in HVAC control panels - ensuring clean, glitch-free logic transitions without external components.
Is SN74AUP1G07DCKRG4 compatible with 1.2-V microcontrollers?
Yes, SN74AUP1G07DCKRG4 is fully specified down to 0.8 V VCC and supports 3.6-V I/O tolerance. When powered at 1.2 V, it correctly interprets 3.3-V input signals (e.g., from a host MCU) and drives open-drain outputs compatible with 1.2-V or 3.3-V pull-ups - making it ideal for voltage translation between ultra-low-power sensor nodes and higher-voltage system controllers.
