Product details
Overview
NC7WV07L6X from onsemi is a dual open-drain buffer IC designed for ultra-low-power logic interfacing in space-constrained systems, operating from 0.9 V to 3.6 V supply, delivering 1.6 ns typical propagation delay at 3.3 V, supporting 24 mA output drive, and featuring IOFF partial power-down protection. It is used in level-shifting I²C bus interfaces and low-voltage sensor signal conditioning.
For engineers reviewing the NC7WV07L6X datasheet, pinout, applications, or equivalent options, key selection criteria include its dual open-drain topology, sub-1.0 V minimum VCC support, ±24 mA sink capability at 3.3 V, overvoltage-tolerant inputs up to 3.6 V, and MicroPak™ 6-pin SIP package footprint.
Technical Context
The NC7WV07L6X implements two independent non-inverting buffers with open-drain outputs, requiring external pull-up resistors for logic-high assertion. Its IOFF circuitry disables input/output leakage paths when VCC = 0 V, enabling live insertion and hot-swap compatibility in multi-rail systems.
It supports mixed-voltage domain interfacing via input overvoltage tolerance (up to 3.6 V regardless of VCC), operates across −40°C to +85°C, and uses CMOS process technology optimized for sub-1 V operation while maintaining rail-to-rail input voltage range compliance.

|---|---|---|
| 1 (A1) | Input 1 | Non-inverting logic input for first buffer channel; tolerant to 3.6 V regardless of VCC |
| 2 (GND) | Ground | Reference return path for both channels; must be connected before VCC for proper IOFF activation |
| 3 (A2) | Input 2 | Non-inverting logic input for second buffer channel; electrically isolated from A1 |
| 4 (Y2) | Output 2 | Open-drain output for second channel; requires external pull-up to define logic-high voltage |
| 5 (VCC) | Supply | Single positive supply input; powers internal logic and enables IOFF control when at 0 V |
| 6 (Y1) | Output 1 | Open-drain output for first channel; independently controllable; shares no internal nodes with Y2 |
Key Features

FAQ
What is the minimum supply voltage supported by the NC7WV07L6X?
The NC7WV07L6X supports a minimum supply voltage of 0.9 V, verified across the full operating temperature range (−40°C to +85°C). This enables reliable operation in deeply discharged lithium coin cells and energy-harvesting systems where rail voltage drops below 1.0 V. The NC7WV07L6X maintains functional logic thresholds and propagation delay specifications down to this limit, as confirmed in the onsemi datasheet Rev. 5, page 3.
Does the NC7WV07L6X support hot-swap or partial power-down operation?
Yes, the NC7WV07L6X includes IOFF circuitry that actively disables input and output leakage paths when VCC = 0 V, preventing back-current flow and signal corruption during hot-insertion or partial system power-down. This feature is explicitly documented in the Features section and DC Electrical Characteristics table (IOFF ≤ 0.5 μA), making NC7WV07L6X suitable for modular systems requiring live module replacement.
What package type and dimensions does the NC7WV07L6X use?
The NC7WV07L6X uses the MicroPak™ SIP6 package (Case 127EB), measuring 1.45 mm × 1.0 mm with 0.5 mm pitch and bottom-mounted terminals. Its mechanical outline is defined in the datasheet page 6 and matches the SIP6 1.45×1.0 specification. Unlike SC-88 variants, NC7WV07L6X has no leads and requires solder paste stencil optimization for assembly - a detail confirmed in the ordering information table.
Can the NC7WV07L6X safely interface with 3.6 V inputs while powered from 1.2 V?
Yes, the NC7WV07L6X inputs are overvoltage-tolerant up to 3.6 V regardless of VCC level, as specified in the Features list and Maximum Ratings table (VIN = −0.5 V to +4.3 V). This allows direct connection of 3.3 V or 3.6 V peripheral outputs to NC7WV07L6X inputs even when VCC is set to 1.2 V, eliminating external clamping components in mixed-voltage I/O architectures.
Is the NC7WV07L6X pin-compatible with other TinyLogic dual buffer variants?
No - the NC7WV07L6X uses a unique 6-pin SIP6 pinout (A1, GND, A2, Y2, VCC, Y1) that differs from SC-88-packaged variants like NC7WV07P6X and is incompatible with 8-pin packages such as US8 or XSON6. Pin assignment is fixed per Figure 1 and PIN ASSIGNMENT table; no alternate pinouts or P2P replacements exist within the TinyLogic ULP-A family for the MicroPak™ variant.
