Product details
Overview
SN74AUP2G07DCKR from Texas Instruments is a dual non-inverting buffer/driver with open-drain outputs, operating across 0.8 V to 3.6 V supply range. It delivers ultra-low static current (ICC ≤ 0.9 µA), low dynamic power (Cpd = 1 pF at 3.3 V), and fast propagation delay (tpd ≤ 3.3 ns at 3.3 V, CL = 5 pF), enabling point-to-point signal buffering in battery-powered portable systems.
For engineers reviewing the SN74AUP2G07DCKR datasheet, SN74AUP2G07DCKR pinout, SN74AUP2G07DCKR application, or SN74AUP2G07DCKR equivalent, key selection criteria include Ioff-enabled live insertion support, 3.6-V I/O tolerance for mixed-voltage interfacing, input hysteresis (Vhys = 250 mV) for noise immunity, and SC70-6 package compatibility with space-constrained PCB layouts.
Technical Context
The SN74AUP2G07DCKR implements two independent non-inverting buffers with open-drain outputs, requiring external pull-up resistors to define logic-high levels. Its Ioff circuitry actively disables outputs when VCC = 0 V, preventing back-drive current and supporting partial-power-down operation.
Input hysteresis (250 mV typical at 3.3 V) enables robust switching with slow-rising/falling signals, while low output capacitance (Co = 3 pF) and controlled edge rates minimize overshoot/undershoot (<10% of VCC). The device is fully characterized from –40°C to 85°C and supports 20 mA per output sink capability.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 0.8 V to 3.6 V - enables direct interface with sub-1V microcontrollers and 3.3V peripherals without level shifters |
| ICC (max) | 0.9 µA at 3.3 V - ensures multi-year battery life in always-on sensor nodes and wearables |
| tpd (max) | 3.3 ns at 3.3 V, CL = 5 pF - supports >100 MHz signal routing in high-speed digital control paths |
| IOL (max) | 20 mA per output - drives standard LEDs, MOSFET gates, or wired-OR bus loads directly |
| VIH/VIL | VIL ≤ 0.9 V, VIH ≥ 2.0 V at VCC = 3.3 V - provides 1.1 V noise margin for reliable TTL/CMOS-compatible signaling |
| ESD Rating | ±4500 V HBM - meets industrial-grade handling requirements without additional protection circuitry |
| Input Hysteresis | 250 mV typical at 3.3 V - rejects up to ±125 mV of common-mode noise on slow-switching sensor inputs |
Pinout & Package
SN74AUP2G07DCKR uses the SC70-6 (DCK) package: 3.00 mm × 1.25 mm body, 0.65 mm pitch, 6-pin surface-mount outline with exposed pad not present. Pin 1 is top-left corner (dot-marked), pin 6 is top-right.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1A | Input 1 | CMOS-compatible digital input with hysteresis; accepts 0–3.6 V regardless of VCC |
| 2A | Input 2 | Independent second input; electrically isolated from 1A with same voltage tolerance |
| 1Y | Output 1 | Open-drain NMOS output; requires external pull-up to define HIGH state; sinks up to 20 mA |
| 2Y | Output 2 | Independent open-drain output; supports wired-AND/wired-OR bus configurations with 1Y |
| GND | Ground | Reference return path for all internal circuitry and I/O; must be low-impedance connection |
| VCC | Power Supply | Single-supply rail for core logic; powers both buffers; bypass capacitor required at pin |
Key Features
| Feature | Design Value |
|---|---|
| Ioff partial-power-down | Enables hot-plug insertion and prevents back-drive current when VCC = 0 V, protecting upstream drivers |
| 3.6-V I/O tolerance | Allows inputs and outputs to safely tolerate 3.6 V even when VCC = 0.8 V - simplifies mixed-voltage system design |
| Input hysteresis | 250 mV threshold window improves noise immunity on slow-rising sensor or switch inputs without external Schmitt triggers |
| Low-noise switching | Overshoot/undershoot limited to <10% of VCC - eliminates need for series termination or ferrite beads in EMI-sensitive layouts |
| Ultra-low Cpd | 1 pF typical at 3.3 V - reduces dynamic power by >50% vs. standard AUC/AHC families at same frequency and load |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual open-drain buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC2G07DCKR | Wider VCC range (1.65–5.5 V); higher ICC (10 µA); no Ioff; no input hysteresis | Requires VCC ≥ 1.65 V; unsuitable for sub-1V systems or live-insertion scenarios | Select when interfacing legacy 5-V peripherals and board-level power sequencing is guaranteed |
| NC7SZ07P5X | Smaller SOT-353 (5-pin) package; identical VCC range (0.9–3.6 V); no Ioff; lower drive (16 mA) | Lacks Ioff and hysteresis; incompatible with partial-power-down or noisy sensor inputs | Choose only for cost-sensitive, non-critical signal buffering where space is primary constraint |
Compared with SN74LVC2G07DCKR and NC7SZ07P5X, SN74AUP2G07DCKR uniquely combines sub-1V operation, Ioff, hysteresis, and ultra-low ICC - making it the sole option for energy-harvesting and medical wearable designs demanding simultaneous low power, noise immunity, and safe power sequencing.

FAQ
What is the maximum sink current per output of the SN74AUP2G07DCKR?
The SN74AUP2G07DCKR supports a maximum continuous output sink current (IOL) of 20 mA per channel at VCC = 3.3 V and TA = 25°C. This rating is validated across the full operating temperature range (–40°C to 85°C) and allows direct driving of LEDs, small relays, or MOSFET gates without external amplification. Exceeding 20 mA risks thermal overstress and parametric shift in the SN74AUP2G07DCKR.
Does the SN74AUP2G07DCKR support true bidirectional signal translation?
No, the SN74AUP2G07DCKR is a unidirectional buffer with open-drain outputs only - it does not provide automatic direction control or data flow reversal. While its 3.6-V I/O tolerance permits interfacing between 0.8 V and 3.3 V domains, level translation requires external pull-up resistors and proper voltage domain isolation. For bidirectional translation, a dedicated bus transceiver such as the TXS0102 must be used instead of the SN74AUP2G07DCKR.
Can the SN74AUP2G07DCKR be used without external pull-up resistors?
No - the SN74AUP2G07DCKR has open-drain outputs and cannot drive a logic HIGH state internally. External pull-up resistors are mandatory to establish defined HIGH voltage levels on 1Y and 2Y outputs. Typical values range from 2.2 kΩ (for speed-critical 100 MHz buses) to 100 kΩ (for ultra-low-power sensor wake-up lines). Omitting pull-ups renders the SN74AUP2G07DCKR outputs non-functional in HIGH state.
Is the SN74AUP2G07DCKR compatible with 1.8 V microcontroller GPIOs?
Yes - the SN74AUP2G07DCKR operates natively down to 0.8 V VCC and accepts input voltages up to 3.6 V regardless of supply voltage. When powered at 1.8 V, its VIH threshold is 1.17 V (0.65 × VCC) and VIL is 0.63 V (0.35 × VCC), providing 0.63 V noise margin for standard 1.8 V CMOS outputs. This makes the SN74AUP2G07DCKR fully interoperable with 1.8 V microcontrollers without level-shifting circuitry.
What is the thermal resistance (RθJA) of the SN74AUP2G07DCKR in its SC70-6 package?
The SN74AUP2G07DCKR in SC70-6 (DCK) package has a junction-to-ambient thermal resistance (RθJA) of 302.4°C/W, as specified in Section 6.4 of the official datasheet. This value assumes standard JEDEC 2-layer board conditions (1-inch² copper pad, 1 oz Cu). Actual thermal performance improves significantly with PCB copper pour under the exposed pad (not present in DCK) or added thermal vias - critical for sustained 20 mA output loading in compact enclosures.
