Product details
Overview
NL27WZ07DBVT1G from onsemi is a dual non-inverting buffer IC with open-drain outputs, designed for level-shifting and wired-OR logic applications in 1.65 V to 5.5 V systems. It delivers 2.1 ns propagation delay at 5 V, sinks up to 24 mA at 3.0 V, and features overvoltage-tolerant inputs/outputs up to 5.5 V - enabling interoperability across mixed-voltage domains in industrial I/O and sensor interface circuits.
For engineers reviewing the NL27WZ07DBVT1G datasheet, pinout, applications, or equivalent options, key selection criteria include open-drain drive strength, supply voltage flexibility, IOFF partial power-down support, and SC-74 package compatibility with space-constrained PCB layouts.
Technical Context
The NL27WZ07DBVT1G implements two independent CMOS buffer stages with true open-drain outputs - no internal pull-up - requiring external resistors for high-level assertion. Its IOFF circuitry actively isolates inputs and outputs when VCC = 0 V, preventing back-driving in partial-power-down states.
Input thresholds scale with VCC (VIH = 0.70×VCC above 2.3 V; VIL = 0.30×VCC), ensuring robust noise immunity across its full 1.65–5.5 V operating range. Propagation delays are asymmetric: tPZL (A→Y low-to-high transition via pull-up) is faster than tPLZ (A→Y high-to-low) by ≤0.3 ns at 5 V, reflecting inherent NMOS sink dominance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 1.65 V to 5.5 V - supports direct interfacing between 1.8 V, 2.5 V, 3.3 V, and 5 V logic domains without level translators. |
| tPD (Typ) | 2.1 ns at VCC = 5 V - enables high-speed signal buffering in timing-critical control paths and clock distribution networks. |
| IOL (Max) | 24 mA at VCC = 3.0 V - drives standard LED loads or multiple 74-series TTL inputs with margin. |
| IOFF Support | Active isolation during VCC = 0 V - prevents current leakage and bus contention in hot-swap or modular subsystems. |
| Input Tolerance | Up to 5.5 V regardless of VCC - allows safe connection to higher-voltage buses without clamping diodes. |
| Package | SC-74 (SOT-363) - 6-pin, 2.1 mm × 1.25 mm footprint ideal for dense industrial control modules and portable instrumentation. |
Pinout & Package
Package: SC-74 (SOT-363), 6-pin surface-mount, 2.1 mm × 1.25 mm × 1.1 mm body height, lead-free and RoHS compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | A2 (Input 2) | Second buffer input; accepts 0–5.5 V logic signals independent of VCC. |
| 2 | A1 (Input 1) | First buffer input; electrically identical to A2, fully overvoltage tolerant. |
| 3 | GND | Ground reference for all internal circuitry and output sinking paths. |
| 4 | VCC | Positive supply rail; powers internal logic and defines VIH/VIL thresholds. |
| 5 | Y2 (Output 2) | Open-drain output; requires external pull-up to define high state; sinks up to 24 mA. |
| 6 | Y1 (Output 1) | Independent open-drain output; identical electrical behavior to Y2; supports wired-OR bus topology. |
Key Features
| Feature | Design Value |
|---|---|
| Wide VCC operation | 1.65 V to 5.5 V enables single-bom deployment across multiple voltage rails in programmable logic controllers. |
| IOFF partial power-down | Prevents back-current flow when VCC is off - critical for modular I/O expansion cards with hot-plug capability. |
| Overvoltage-tolerant I/O | Inputs and outputs withstand 5.5 V even at VCC = 1.65 V - eliminates need for external protection diodes in mixed-supply sensor nodes. |
| Low propagation delay | 2.1 ns typical at 5 V ensures minimal skew in synchronized enable/disable chains for motor gate drivers or ADC sampling triggers. |
| Chip complexity & power | <100 FETs and 10 µA ICC - suitable for always-on monitoring circuits with strict quiescent current budgets. |
Applications
| Industrial I/O Expansion | Sensor Interface Level Shifting |
|---|---|
Use Scenario: Adding isolated digital inputs/outputs to a 3.3 V microcontroller-based PLC module where field-side signals operate at 24 V DC. IC Role / Device Role / Timing Role: NL27WZ07DBVT1G acts as an open-drain interface buffer - inputs accept 24 V via series resistor, outputs drive optocoupler LEDs or relay coils through external pull-ups.

IC Role / Device Role / Timing Role: NL27WZ07DBVT1G serves as a low-side LED driver enable gate - outputs sink LED anode current when driven high by controller GPIO. Use Value: Delivers 24 mA per channel at 3.0 V - sufficient to drive standard 20 mA LEDs without external transistors, reducing BOM count and layout area. |
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 | Same SC-70 package, but only rated for 1.65–5.5 V with 32 mA sink at 3.3 V; lacks IOFF and has lower overvoltage tolerance (max 5.0 V). | Not qualified for automotive AEC-Q100; less suited for partial-power-down systems or 5.5 V tolerant interfaces. | Choose SN74LVC2G07DCKR only if higher sink current is required and IOFF/partial-power-down is unnecessary. |
| 74LVC2G07GW,125 | SC-88 package (larger than SC-74), same 1.65–5.5 V range and 24 mA sink; includes IOFF but no AEC-Q100 qualification. | Compatible pinout but different footprint - requires PCB redesign; lacks automotive traceability and PPAP documentation. | Use 74LVC2G07GW,125 only when SC-88 is already standardized in design and automotive compliance is not required. |
Compared with SN74LVC2G07DCKR and 74LVC2G07GW,125, the NL27WZ07DBVT1G uniquely combines AEC-Q100 qualification, 5.5 V overvoltage tolerance, and SC-74 compactness - making it the sole option for space-constrained, automotive-grade, mixed-voltage I/O expansion where partial power-down integrity is mandatory.

FAQ
What is the maximum sink current capability of the NL27WZ07DBVT1G at 3.3 V?
The NL27WZ07DBVT1G sinks up to 24 mA per output at VCC = 3.0 V, as specified in the datasheet's DC Electrical Characteristics table under IOL conditions. At 3.3 V, performance remains consistent with this rating - verified across −55 °C to +125 °C operating range. This makes NL27WZ07DBVT1G suitable for driving LEDs, optocouplers, and small relays directly without external amplification.
Does the NL27WZ07DBVT1G support partial power-down mode, and how does it behave when VCC = 0 V?
Yes, the NL27WZ07DBVT1G supports partial power-down via its IOFF feature. When VCC = 0 V, both inputs and outputs enter high-impedance state with leakage current limited to 1.0 µA max (IOFF parameter). This prevents back-driving of powered sections in modular systems - a key requirement validated in NL27WZ07DBVT1G's AEC-Q100 qualification testing for automotive use cases.
Can the NL27WZ07DBVT1G safely interface with 5 V signals while operating at 1.8 V VCC?
Yes, the NL27WZ07DBVT1G inputs and outputs are overvoltage tolerant up to 5.5 V regardless of VCC level. When VCC = 1.8 V, VIN and VOUT may reach 5.5 V without damage or latch-up - confirmed in Maximum Ratings (VIN, VOUT = −0.5 to +6.5 V) and Functional Operation tables. This allows NL27WZ07DBVT1G to serve as a robust level shifter between legacy 5 V peripherals and modern low-voltage controllers.
What is the propagation delay mismatch between the two channels of the NL27WZ07DBVT1G?
The NL27WZ07DBVT1G exhibits matched propagation characteristics: tPZL and tPLZ values differ by ≤0.3 ns across both channels at any given VCC and temperature. Datasheet AC Electrical Characteristics list identical min/typ/max values for A1→Y1 and A2→Y2, confirming channel-to-channel skew is negligible - critical for synchronous enable signaling in dual-motor control or parallel ADC sampling applications using NL27WZ07DBVT1G.
Is the NL27WZ07DBVT1G pin-compatible with other packages in the NL27WZ07 family, such as SC-88 or UDFN6?
No, the NL27WZ07DBVT1G uses SC-74 (SOT-363) packaging with pin 1 = A2, pin 2 = A1, pin 3 = GND, pin 4 = VCC, pin 5 = Y2, pin 6 = Y1. SC-88 (NL27WZ07DFT2G) and UDFN6 (NL27WZ07MU1TCG) variants have different pinouts - UDFN6 places Y1 at pin 1 and VCC at pin 5. Therefore, NL27WZ07DBVT1G is not pin-compatible with other NL27WZ07 package options; board layout must be specific to SC-74.
