Product details
Overview
SN74AUP1G07DCKRE4 from Texas Instruments is a single non-inverting buffer with open-drain output, operating across 0.8 V to 3.6 V supply range. It delivers ultra-low static current (ICC ≤ 0.9 µA), 1 pF typical dynamic power capacitance at 3.3 V, and 3.3 ns max propagation delay at 3.3 V. Used in voltage-level translation and wired-OR bus interfaces for portable medical and industrial sensor systems.
For engineers reviewing the SN74AUP1G07DCKRE4 datasheet, SN74AUP1G07DCKRE4 pinout, SN74AUP1G07DCKRE4 application, or SN74AUP1G07DCKRE4 equivalent, key selection criteria include Ioff-enabled live insertion support, 0.8 V logic compatibility, input hysteresis (250 mV typ), 3.6-V I/O tolerance, and SC70-5 package footprint (2.0 mm × 1.25 mm).
Technical Context
The SN74AUP1G07DCKRE4 implements a CMOS-based single-buffer architecture with open-drain output stage, enabling wired-AND/wired-OR logic sharing. Its Ioff circuitry actively disables outputs when VCC = 0 V, preventing back-drive current and supporting partial-power-down operation.
Input hysteresis (250 mV typ at 3.3 V) improves noise immunity against slow-rising signals, while low input capacitance (1.5 pF typ) minimizes loading on driving sources. The device is fully characterized from –40°C to +85°C and supports mixed-voltage interfacing via 3.6-V tolerant I/Os.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 0.8 V to 3.6 V - enables direct interface with sub-1 V microcontrollers and legacy 3.3 V peripherals |
| ICC (Max) | 0.9 µA at 25°C - ensures multi-year battery life in always-on wearable sensors |
| tpd (Max) | 3.3 ns at 3.3 V, CL = 5 pF - supports high-speed signal buffering without timing closure issues |
| Ioff (Max) | 0.6 µA at 0 V - guarantees safe live insertion and back-drive protection during hot-swap events |
| Input Hysteresis | 250 mV typ at 3.3 V - rejects >100 mV of switching noise on slow-transitioning sensor inputs |
| IOH/IOL | ±20 mA output drive - sufficient to sink LED indicators or drive 10-cm PCB traces with 50 Ω impedance |
| Ci (Typ) | 1.5 pF - reduces capacitive loading on high-impedance analog sensor outputs |
Pinout & Package
SN74AUP1G07DCKRE4 uses the SC70-5 (DCK) package: 2.00 mm × 1.25 mm body, 0.65 mm height, 0.65 mm lead pitch. Pin 1 is marked with a dot; Pin 3 is GND; Pin 5 is VCC.
| 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 | CMOS-compatible digital input with hysteresis; accepts 0–3.6 V regardless of VCC |
| 3 | GND | Primary ground reference for logic and power domains; requires low-inductance PCB connection |
| 4 | Output Y | Open-drain NMOS output - requires external pull-up to define high state; supports wired-OR |
| 5 | VCC | Single-supply rail (0.8–3.6 V); bypass capacitor (0.1 µF) required within 2 mm of this pin |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low ICC | 0.9 µA max enables >10-year operation on coin-cell batteries in remote monitoring nodes |
| Ioff Protection | Active at VCC = 0 V - eliminates risk of damaging current flow during board hot-plug or power sequencing |
| Input Hysteresis | 250 mV typ - allows reliable switching even with <1 V/ns slew-rate signals from thermistor or pressure bridges |
| 3.6-V I/O Tolerance | Supports level-shifting from 3.3 V peripherals to 0.8 V cores without external translators |
| SC70-5 Footprint | 2.0 mm × 1.25 mm area - saves >60% board space vs. SOT-23-5 in dense portable designs |

Equivalent & Alternatives
The following parts are listed as comparable options for similar buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC1G07DCKR | Wider VCC range (1.65–5.5 V); higher ICC (10 µA typ); no Ioff; 5.5 ns tpd at 3.3 V | Not suitable for sub-1 V systems or hot-swap scenarios; better for legacy 5 V mixed-signal boards | Select only if system operates ≥1.65 V and does not require live insertion or ultra-low standby current |
| NC7SZ07P5X | Same SC70-5 package; VCC = 1.65–5.5 V; ICC = 1 µA typ; no Ioff; 3.5 ns tpd at 3.3 V | Lacks Ioff and sub-1 V support; lower hysteresis (150 mV); RoHS-compliant but not automotive-qualified | Prefer for cost-sensitive consumer devices where 0.8 V operation and hot-swap are not required |
Compared with SN74LVC1G07DCKR and NC7SZ07P5X, SN74AUP1G07DCKRE4 uniquely supports 0.8 V operation, delivers 10× lower ICC, and provides Ioff for safe partial-power-down-making it the only choice for battery-powered medical and portable industrial edge nodes requiring long-term reliability and mixed-voltage interoperability.

FAQ
What is the minimum supply voltage supported by SN74AUP1G07DCKRE4?
SN74AUP1G07DCKRE4 operates down to 0.8 V, enabling direct integration with next-generation ultra-low-power microcontrollers and energy-harvesting sensor nodes. This 0.8 V minimum is confirmed in Section 7.3 (Recommended Operating Conditions) of the SCES591J datasheet and validated across –40°C to +85°C ambient temperature.
Does SN74AUP1G07DCKRE4 support live insertion or hot-swap?
Yes, SN74AUP1G07DCKRE4 includes Ioff circuitry that disables outputs when VCC = 0 V, preventing damaging back-current flow during live insertion. This feature is explicitly documented in the Features section and Functional Description (Section 9.1) of the official TI datasheet SCES591J.
What is the purpose of the N.C. pin on SN74AUP1G07DCKRE4?
Pin 1 of SN74AUP1G07DCKRE4 is designated No Connection (N.C.) - it has no internal bond wire or silicon connection. Per TI's Pin Configuration documentation (Section 6), this pin may be left floating or tied to GND for mechanical stability; it must never be driven or used as a signal path.
Can SN74AUP1G07DCKRE4 drive a 3.3 V pull-up while powered from 1.2 V?
Yes, SN74AUP1G07DCKRE4 features 3.6-V I/O tolerance, allowing its open-drain output (Pin 4) to safely interface with 3.3 V pull-up resistors even when VCC = 1.2 V. This capability is specified in Section 7.3 (Recommended Operating Conditions) and enables seamless level translation without external components.
How does input hysteresis improve noise immunity in SN74AUP1G07DCKRE4?
SN74AUP1G07DCKRE4 provides 250 mV typical input hysteresis at 3.3 V, meaning the input threshold rises to ~1.85 V for a high-to-low transition and falls to ~1.6 V for low-to-high. This 250 mV window rejects transient noise spikes below that amplitude, ensuring clean switching on slow-rising sensor outputs - a key benefit confirmed in Section 9.3 (Feature Description) of SCES591J.
