Product details
Overview
NL27WZ06DBVT1G from onsemi is a dual inverter IC with open-drain outputs, designed for level-shifting and wired-OR logic applications in mixed-voltage systems. It operates from 1.65 V to 5.5 V, delivers 2.1 ns typical propagation delay at 5 V, sinks up to 24 mA at 3.0 V, and supports overvoltage-tolerant inputs/outputs up to 5.5 V - enabling robust interfacing between 1.8 V, 2.5 V, 3.3 V, and 5 V domains.
For engineers reviewing the NL27WZ06DBVT1G datasheet, pinout, applications, or equivalent options, key selection criteria include open-drain drive strength, supply voltage flexibility, partial power-down (IOFF) support, and SC-74 package compatibility with space-constrained PCB layouts.
Technical Context
The NL27WZ06DBVT1G integrates two independent inverting buffers, each with an open-drain output stage that requires an external pull-up resistor to define high-level voltage and logic threshold. Its IOFF circuitry actively disables input/output leakage when VCC = 0 V, preventing back-powering of powered-down system sections.
Input thresholds scale with VCC (VIH = 0.70×VCC above 2.3 V; VIL = 0.30×VCC), ensuring consistent noise margin across supply voltages. Propagation delays are specified down to 1.65 V (tPZL/tPLZ ≤ 9.5 ns), supporting low-voltage operation without timing degradation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.65 V to 5.5 V - enables direct interface across 1.8 V, 2.5 V, 3.3 V, and 5 V logic families without level translators. |
| Propagation Delay (Typ) | 2.1 ns at VCC = 5 V - supports high-speed signal inversion in timing-critical paths such as clock enable or reset distribution. |
| Output Sink Current | 24 mA at VCC = 3.0 V - drives standard TTL loads or multiple CMOS inputs with margin; sufficient for LED indicators or I²C bus pull-downs. |
| Input Overvoltage Tolerance | Up to 5.5 V regardless of VCC - allows safe connection to higher-voltage signals (e.g., 5 V microcontroller GPIO) while operating at 1.8 V. |
| IOFF Leakage Current | ≤10 µA at VCC = 0 V - prevents current flow between powered and unpowered subsystems during partial power-down modes. |
| Input Capacitance | 2.5 pF - minimizes capacitive loading on driving sources, preserving signal integrity in high-frequency or fan-out-sensitive nodes. |
Pinout & Package
Package: SC-74 (Case 318F-05), 6-pin surface-mount package measuring 2.0 mm × 1.25 mm × 0.9 mm with 0.65 mm pitch.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | A2 (Input 2) | Inverting input for second buffer channel; accepts 0–5.5 V logic levels independent of VCC. |
| 2 | A1 (Input 1) | Inverting input for first buffer channel; compatible with sub-2 V logic families and 5 V tolerant. |
| 3 | GND | Ground reference for both logic and power domains; must be connected before applying VCC or inputs. |
| 4 | VCC | Positive supply rail (1.65–5.5 V); powers internal logic and defines output high-level threshold via external pull-up. |
| 5 | Y2 (Output 2) | Open-drain output for second inverter; requires external pull-up to define VOH and drive strength. |
| 6 | Y1 (Output 1) | Open-drain output for first inverter; electrically isolated from Y2; supports independent wired-OR configuration. |
Key Features
| Feature | Design Value |
|---|---|
| Wide VCC range (1.65–5.5 V) | Eliminates need for separate level-shifting ICs when interfacing mixed-voltage peripherals like sensors, displays, or legacy controllers. |
| IOFF partial power-down protection | Blocks bidirectional current flow during VCC = 0 V conditions, protecting live buses and enabling hot-swap capability in modular systems. |
| Overvoltage-tolerant inputs/outputs | Accepts 5.5 V signals even at 1.65 V VCC, simplifying design of universal I/O expanders or FPGA configuration interfaces. |
| Low propagation delay (2.1 ns typ @ 5 V) | Preserves timing margins in high-speed control loops, such as PWM gate drivers or real-time interrupt conditioning circuits. |
| SC-74 footprint compatibility | Matches industry-standard 6-pin small-outline package; enables drop-in replacement in space-constrained industrial and automotive modules. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual inverter with open-drain output applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC2G06DCKR | Same SC-70-6 package, but rated only to 3.6 V VCC max; no overvoltage tolerance beyond VCC; IOFF not specified. | Limited to single-supply 1.65–3.6 V systems; unsuitable for 5 V tolerant or mixed-voltage bus applications. | Select SN74LVC2G06DCKR only when full 5.5 V tolerance and IOFF are unnecessary and cost is primary constraint. |
| MC74VHC1G06DTT1G | SC-74 package, 2–5.5 V VCC range, but lacks IOFF and overvoltage tolerance; tPD = 7.5 ns @ 5 V (slower). | Acceptable for basic inversion where power sequencing is controlled externally; not recommended for partial power-down architectures. | Choose MC74VHC1G06DTT1G for non-automotive consumer designs where AEC-Q100 qualification and robustness are not required. |
Compared with SN74LVC2G06DCKR and MC74VHC1G06DTT1G, the NL27WZ06DBVT1G uniquely combines 5.5 V overvoltage tolerance, IOFF protection, and AEC-Q100 qualification - making it the only option qualified for automotive and industrial hot-swap applications requiring guaranteed isolation during power transitions.

FAQ
What is the maximum supply voltage rating for NL27WZ06DBVT1G?
The NL27WZ06DBVT1G has an absolute maximum DC supply voltage (VCC) rating of +6.5 V, but its recommended operating range is 1.65 V to 5.5 V. Operation above 5.5 V voids functional guarantees and risks permanent damage, as confirmed in the Maximum Ratings table on page 3 of the official datasheet.
Does NL27WZ06DBVT1G support true bidirectional level shifting like a dedicated translator IC?
No - the NL27WZ06DBVT1G is a unidirectional inverter with open-drain outputs and does not auto-detect direction or support passive bidirectional data flow. It enables level shifting only when used in configured pairs (e.g., one for SDA, one for SCL) with external pull-ups tied to the target voltage domain.
Is NL27WZ06DBVT1G pin-compatible with other SC-74 dual inverters such as MC74VHC1G06DTT1G?
Yes - NL27WZ06DBVT1G uses the same SC-74 (Case 318F-05) mechanical outline and identical pin assignment (A2, A1, GND, VCC, Y2, Y1) as MC74VHC1G06DTT1G, enabling physical board compatibility. However, electrical behavior differs significantly due to IOFF and overvoltage tolerance features absent in the VHC variant.
Can NL27WZ06DBVT1G drive an LED directly without a series resistor?
No - although NL27WZ06DBVT1G sinks up to 24 mA at 3.0 V, driving an LED without a current-limiting resistor risks exceeding absolute maximum output current (±50 mA) and damaging the output FET. A minimum series resistor of 100 Ω is required for typical red/green LEDs at 3.3 V.
What does the "−Q" suffix mean in NL27WZ06DBVT1G-Q, and is NL27WZ06DBVT1G itself AEC-Q100 qualified?
The "−Q" suffix denotes automotive-specific change control and PPAP capability, but NL27WZ06DBVT1G itself is AEC-Q100 qualified (Grade 1, −40 °C to +125 °C) as stated in the Features section on page 1. The base part meets automotive reliability standards without requiring the −Q variant unless site-specific manufacturing controls are mandated.
