Product details
Overview
SN74AUC2G07DBVT from Texas Instruments is a dual non-inverting buffer/driver with open-drain outputs, designed for 1.65-V to 1.95-V operation and 3.6-V I/O tolerant interfacing. It delivers ±8-mA sink/source drive at 1.8 V, achieves 2.5 ns max propagation delay, and supports partial-power-down via Ioff. It is used in level-shifting, wired-AND logic, and bus interface applications in portable and low-voltage embedded systems.
For engineers reviewing the SN74AUC2G07DBVT datasheet, SN74AUC2G07DBVT pinout, SN74AUC2G07DBVT application, or SN74AUC2G07DBVT equivalent, key selection criteria include open-drain compatibility, sub-2-V operation, Ioff-enabled power sequencing, 6-pin SOT-23 package constraints, and 32-mA absolute max sink current capability.
Technical Context
This device implements two independent non-inverting buffers, each with an open-drain output stage enabling wired-logic configurations. Its Ioff circuitry actively disables outputs during power-down, preventing backflow current when VCC = 0 V.
It operates across 0.8 V to 2.7 V supply range but is optimized for 1.65–1.95 V; input thresholds scale with VCC (VIH = 0.65×VCC, VIL = 0.35×VCC), and output voltage swing extends to VCC + 0.5 V under load.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 0.8 V to 2.7 V - supports ultra-low-voltage operation down to sub-1-V, with optimal performance at 1.65–1.95 V |
| Max tpd | 2.5 ns at 1.8 V, CL = 15 pF - enables high-speed signal buffering in compact timing-critical paths |
| IOL (1.8 V) | ±8 mA - sufficient drive strength for direct connection to 3.3-V or 5-V pull-up networks |
| Ioff Current | ±10 µA at VI/VO = 2.7 V - ensures robust isolation during partial power-down without external disable logic |
| IO(max) Sink | 32 mA - allows direct driving of LEDs or higher-current loads without external transistor stages |
| Input Thresholds | VIH = 0.65×VCC, VIL = 0.35×VCC - provides hysteresis-free CMOS-compatible switching across full VCC range |
| ESD Rating | 2000-V HBM, 200-V MM, 1000-V CDM - meets industrial-grade robustness requirements without added protection circuitry |
Pinout & Package
SOT-23 (DBV) 6-pin package: 2.9 mm × 1.6 mm × 1.45 mm body, gull-wing leads, RoHS-compliant NiPdAu finish, MSL Level-1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (A1) | Input of Buffer 1 | CMOS-compatible digital input; must be tied to VCC or GND if unused to prevent floating node instability |
| 2 (Y1) | Open-Drain Output of Buffer 1 | Active-low wired-OR capable; requires external pull-up; sinks up to 32 mA |
| 3 (GND) | Ground Reference | Primary return path for all internal logic and output current; must be low-impedance for noise immunity |
| 4 (Y2) | Open-Drain Output of Buffer 2 | Independent from Y1; supports separate wired-AND functions or dual-channel level translation |
| 5 (A2) | Input of Buffer 2 | Electrically isolated from A1; accepts same input voltage range and threshold scaling |
| 6 (VCC) | Supply Voltage | Power rail for both buffers; supplies internal logic and enables Ioff control during power sequencing |
Key Features
| Feature | Design Value |
|---|---|
| NanoFree™ WCSP option available | Die-as-package construction reduces footprint and thermal resistance - not applicable to SN74AUC2G07DBVT (SOT-23 variant) |
| Ioff partial-power-down support | Enables safe hot-insertion and multi-rail sequencing by disabling outputs when VCC = 0 V |
| 3.6-V I/O tolerance | Allows interfacing with higher-voltage systems (e.g., 3.3-V buses) while powered from 1.8-V rails |
| Low ICC (10 µA at 1.8 V) | Minimizes quiescent power in always-on subsystems such as battery-backed IO expanders or sensor interfaces |
| Sub-1-V operable | Functional down to 0.8 V VCC - supports emerging ultra-low-power microcontroller domains and energy-harvesting nodes |
Applications
| Level-Shifting Interface | Wired-AND Bus Control |
|---|---|

Use Scenario: Implementing system-wide interrupt aggregation from multiple 1.8-V peripherals onto a shared active-low IRQ line. IC Role / Device Role / Timing Role: Each SN74AUC2G07DBVT output connects to common interrupt net; any asserted output pulls line low (wired-OR). Use Value: Enables deterministic interrupt prioritization without additional logic gates or microcontroller polling overhead. |
| Low-Power Sensor Hub | Hot-Swap IO Expansion |
|
Use Scenario: Driving LED status indicators and enabling/disabling analog sensor bias in a wearable health monitor powered from coin-cell battery.

Use Value: Achieves <10 µA standby current while retaining fast turn-on response (<2.5 ns) for real-time feedback. |
Use Scenario: Adding modular peripheral cards to a baseboard where card insertion occurs while main system remains powered. IC Role / Device Role / Timing Role: SN74AUC2G07DBVT isolates card-side signals using Ioff during insertion; outputs remain high-Z until VCC stabilizes. Use Value: Prevents back-driving of live system rails, eliminating risk of latch-up or data corruption during hot-plug events. |
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 |
|---|---|---|---|
| SN74LVC2G07DBVT | Higher VCC min (1.65 V), lower drive (±24 mA at 3.3 V), slower tpd (3.5 ns at 3.3 V) | Optimized for 3.3-V systems; lacks sub-1-V operation and 1.8-V timing optimization | Select when operating at ≥3.3 V or requiring broader voltage margin over temperature |
| NC7SZ07P5X | Single-channel, SC-70-5 package, 3.6-V tolerant, 1.65–5.5-V operation, 3.2 ns tpd at 3.3 V | Requires two devices for dual-channel use; smaller footprint but no Ioff support | Select when board space is critical and partial-power-down is not required |
Compared with SN74LVC2G07DBVT and NC7SZ07P5X, the SN74AUC2G07DBVT uniquely combines sub-1-V operability, 2.5 ns speed at 1.8 V, and Ioff - making it the only choice for battery-constrained, mixed-voltage, hot-swap-sensitive designs requiring dual-channel open-drain buffering.

FAQ
What is the maximum sink current capability of the SN74AUC2G07DBVT?
The SN74AUC2G07DBVT supports a maximum sink current of 32 mA per output, verified under absolute maximum ratings. This allows direct driving of moderate-current loads like LEDs or termination networks without external transistors. The rated output drive is ±8 mA at 1.8 V under standard switching conditions, balancing speed and power efficiency.
Does the SN74AUC2G07DBVT support partial-power-down operation?
Yes, the SN74AUC2G07DBVT features Ioff circuitry that disables both outputs when VCC = 0 V, limiting off-state current to ±10 µA. This prevents damaging back-current flow during hot-swap or multi-rail power sequencing - a critical requirement in modular systems and battery-powered devices where subsystems power up/down independently.
Can the SN74AUC2G07DBVT interface between 1.8-V and 3.3-V logic domains?
Yes, the SN74AUC2G07DBVT is explicitly 3.6-V I/O tolerant, meaning its inputs and outputs safely accept voltages up to 3.6 V regardless of VCC level. When powered from 1.8 V, it can drive a 3.3-V pull-up network and correctly interpret 3.3-V logic highs - enabling seamless level shifting without external components.
What is the typical propagation delay of the SN74AUC2G07DBVT at 1.8 V?
The SN74AUC2G07DBVT achieves a maximum propagation delay (tpd) of 2.5 ns at 1.8 V with CL = 15 pF, and typical values as low as 1.8 ns under the same conditions. This performance is guaranteed across –40°C to 85°C and makes it suitable for high-speed clock distribution, data strobing, and real-time control loops in compact embedded systems.
Is the SN74AUC2G07DBVT pin-compatible with other dual buffer variants in the same package?
No - the SN74AUC2G07DBVT has a fixed 6-pin SOT-23 (DBV) pinout (1:A1, 2:Y1, 3:GND, 4:Y2, 5:A2, 6:VCC) that differs from inverting or push-pull dual buffers (e.g., SN74AUC2G17). While physical package dimensions match other DBV-6 devices, electrical functionality and pin assignments are unique to the open-drain buffer configuration.
