Product details
Overview
NL27WZ16MU1TCG from onsemi is a dual non-inverting buffer IC operating from 1.65 V to 5.5 V supply, delivering 2.4 ns propagation delay at 5 V, ±32 mA output drive, and overvoltage-tolerant inputs/outputs up to 5.5 V. It serves as a level-shifting and signal fan-out device in low-power digital interfaces of portable instrumentation and industrial control modules.
For engineers reviewing the NL27WZ16MU1TCG datasheet, pinout, applications, or equivalent options, key selection criteria include supply voltage flexibility (1.65–5.5 V), IOFF partial power-down capability, 1.45 mm × 1.0 mm UDFN6 package footprint, and AEC-Q100 qualification for automotive-adjacent systems.
Technical Context
The NL27WZ16MU1TCG implements two independent CMOS buffer stages with rail-to-rail input compatibility and push-pull outputs. Its IOFF feature disables current flow when VCC = 0 V, enabling live insertion and hot-swap operation without back-driving powered subsystems.
Designed for mixed-voltage system interfacing, it supports bidirectional level translation between 1.8 V, 2.5 V, 3.3 V, and 5 V logic domains. The device exhibits consistent timing performance across −55 °C to +125 °C, validated under AEC-Q100 Grade 1 conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.65 V to 5.5 V - Enables interoperability across legacy 5 V and modern ultra-low-power 1.8 V microcontroller I/O rails. |
| Propagation Delay (tPD) | 2.4 ns at VCC = 5 V (typ) - Supports >200 MHz signal integrity in high-speed data path buffering. |
| Output Drive Strength | Sink/source up to 32 mA at 4.5 V - Drives multiple standard TTL or CMOS loads without external buffers. |
| Input Overvoltage Tolerance | Up to 5.5 V regardless of VCC - Allows safe connection to higher-voltage buses during power sequencing or fault conditions. |
| IOFF Current | ≤10 µA at VCC = 0 V - Prevents leakage-induced corruption in partial power-down states. |
| Operating Temperature | −55 °C to +125 °C - Qualified for under-hood automotive, industrial motor control, and outdoor embedded applications. |
| ESD Rating (HBM) | 2000 V - Provides robust handling margin during board assembly and field service. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC2G126DCUR | 3-state outputs (not true buffers); 3.6 V max VCC; no IOFF; 3.5 ns tPD @ 3.3 V | Requires external pull-ups for high-Z default state; unsuitable for partial power-down systems | Select when tri-state control is needed and VCC ≤ 3.6 V; avoid where live insertion or 5 V tolerance is required. |
| 74LVC2G17GW,125 | Schmitt-trigger inputs; same VCC range and package; 3.2 ns tPD @ 3.3 V; no overvoltage tolerance | Better noise immunity on slow-rising signals but incompatible with 5 V inputs or fast-edge clean-up | Choose for noisy industrial sensor lines with slow slew rates; reject if interfacing to 5 V buses or requiring precise timing matching. |
Compared with SN74LVC2G126DCUR and 74LVC2G17GW,125, the NL27WZ16MU1TCG uniquely combines 5.5 V overvoltage tolerance, IOFF shutdown, and sub-2.5 ns delay across its full 1.65–5.5 V range-making it the only option for robust, wide-supply dual buffering in space-constrained automotive and industrial designs.

FAQ
What is the maximum input voltage the NL27WZ16MU1TCG can tolerate when VCC = 1.8 V?
The NL27WZ16MU1TCG supports input voltages up to 5.5 V regardless of VCC level. When VCC = 1.8 V, the inputs remain overvoltage-tolerant to 5.5 V, enabling safe interfacing with higher-voltage peripherals without external clamping diodes or level shifters. This behavior is explicitly specified in the "Inputs/Outputs Overvoltage Tolerant up to 5.5 V" feature and confirmed in the Absolute Maximum Ratings table (VIN = −0.5 V to +6.5 V).
Does the NL27WZ16MU1TCG support partial power-down mode, and how is it implemented?
Yes, the NL27WZ16MU1TCG supports partial power-down via its IOFF feature. When VCC = 0 V, the input and output ports enter a high-impedance state with leakage current limited to ≤10 µA, preventing back-current flow into powered sections of the system. This is validated in the DC Electrical Characteristics table under IOFF parameter and enables hot-swap capability in modular test equipment and reconfigurable industrial controllers.
What is the thermal resistance (θJA) of the NL27WZ16MU1TCG in its UDFN6 package?
The NL27WZ16MU1TCG in the UDFN6 (1.45 mm × 1.0 mm, Case 517AQ) package has a junction-to-ambient thermal resistance (θJA) of 154 °C/W, measured per JESD51-7 on an FR4 board with minimum pad spacing and no airflow. This value is documented in the Maximum Ratings table and confirms suitability for thermally dense layouts in compact industrial and automotive modules.
Is the NL27WZ16MU1TCG qualified for automotive applications, and what standards does it meet?
Yes, the NL27WZ16MU1TCG is AEC-Q100 qualified (Grade 1: −40 °C to +125 °C ambient) and PPAP capable. It meets stress testing requirements for temperature cycling, humidity bias, and ESD (2000 V HBM), as stated in the datasheet features section and ordering information footnote. These qualifications make it suitable for automotive body electronics, infotainment interfaces, and ADAS auxiliary functions-not safety-critical powertrain systems.
Can the NL27WZ16MU1TCG be used for level translation between 1.8 V and 5 V logic domains?
Yes, the NL27WZ16MU1TCG performs bidirectional level translation between 1.8 V and 5 V domains. Its overvoltage-tolerant inputs accept 5 V signals at any VCC ≥1.65 V, while its push-pull outputs swing rail-to-rail. When powered at 1.8 V, it correctly interprets 5 V inputs and drives 1.8 V-compatible loads; when powered at 5 V, it drives 5 V outputs while accepting 1.8 V inputs as valid logic levels per VIH/VIL specs.
