Product details
Overview
NL27WZ16MU2TCG from onsemi is a dual non-inverting buffer IC operating from 1.65 V to 5.5 V, delivering 2.4 ns propagation delay at 5 V, ±32 mA output drive, overvoltage-tolerant inputs/outputs up to 5.5 V, and IOFF partial power-down protection - used in level-shifting, bus buffering, and signal conditioning in space-constrained industrial control and portable electronics.
For engineers reviewing the NL27WZ16MU2TCG datasheet, pinout, applications, or equivalent options, key selection criteria include supply voltage flexibility (1.65–5.5 V), UDFN6-6 1.2×1.0 mm package footprint, guaranteed tri-state behavior, IOFF leakage <10 µA, and AEC-Q100 qualification for automotive-adjacent designs.
Technical Context
The NL27WZ16MU2TCG implements two independent CMOS buffer stages with rail-to-rail input tolerance and active-drive outputs capable of sinking 32 mA at 4.5 V. Its IOFF circuitry disables I/O paths when VCC = 0 V, preventing back-driving in partial-power-down systems.
It supports mixed-voltage interfacing across 1.65 V, 2.5 V, 3.3 V, and 5 V domains due to input thresholds scaling with VCC (VIH = 0.7×VCC min at ≥2.3 V) and output swing to within 0.1 V of rails under load - enabling seamless integration into heterogeneous logic subsystems without external level translators.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.65 V to 5.5 V - enables single-supply operation across legacy 5 V and modern low-voltage microcontroller I/O domains. |
| Propagation Delay (tPD) | 2.4 ns typical at VCC = 5 V, RL = 1 MΩ, CL = 15 pF - ensures minimal timing skew in high-speed digital interfaces. |
| Output Drive Strength | Sinks 32 mA at VCC = 4.5 V - drives multiple standard TTL/CMOS loads or short PCB traces without buffering. |
| Input Overvoltage Tolerance | Up to 5.5 V regardless of VCC - allows safe interfacing with higher-voltage peripherals even during brown-out conditions. |
| IOFF Leakage Current | <10 µA at VCC = 0 V - prevents current backflow and signal corruption in hot-swap or partial-power-down configurations. |
| Operating Temperature | −55 °C to +125 °C - supports deployment in extended-temperature industrial and automotive under-hood environments. |
| ESD Rating (HBM) | 2000 V - provides robust handling margin during board assembly and field service. |
Pinout & Package
Package: UDFN6 (1.2 mm × 1.0 mm, 0.4 mm pitch), 0.5 mm height, wettable flank terminals, RoHS-compliant, Pb-free.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Y1 (Output) | Inverted logic sense not applied - true non-inverting buffer output; compatible with 1.65–5.5 V logic families. |
| 2 | A2 (Input) | Second independent buffer input; accepts overvoltage signals up to 5.5 V regardless of VCC level. |
| 3 | A1 (Input) | First buffer input; shares same voltage-tolerant architecture as A2; supports mixed-voltage domain bridging. |
| 4 | Y2 (Output) | Second non-inverting buffer output; electrically isolated from Y1; each channel operates independently. |
| 5 | GND | Dedicated ground reference for both buffers; must be connected to system ground plane for noise immunity and thermal dissipation. |
| 6 | VCC | Single positive supply input; powers both buffers; IOFF activation occurs automatically when VCC = 0 V. |
Key Features
| Feature | Design Value |
|---|---|
| Wide Supply Range | 1.65–5.5 V operation eliminates need for separate voltage regulators in multi-rail systems. |
| Overvoltage-Tolerant I/O | Inputs and outputs withstand 5.5 V regardless of VCC - enables direct connection to 5 V buses while powered from 3.3 V or lower. |
| IOFF Partial Power-Down | Automatic high-impedance state on all I/O pins when VCC = 0 V - prevents back-current and data corruption during power sequencing. |
| Low Propagation Delay | 2.4 ns typical at 5 V supports >200 MHz toggle rates in clock distribution or data path applications. |
| AEC-Q100 Qualified | Qualified per AEC-Q100 Rev-G Grade 1 (−40 °C to +125 °C) - suitable for automotive infotainment, body control, and ADAS auxiliary logic. |
Applications
| Industrial PLC I/O Expansion | Automotive Body Control Module |

FAQ
What is the maximum operating temperature range for the NL27WZ16MU2TCG?
The NL27WZ16MU2TCG is rated for operation from −55 °C to +125 °C, meeting extended industrial and automotive under-hood requirements. This specification is validated per the Recommended Operating Conditions table in the official onsemi datasheet (Rev. 13, May 2023), and applies directly to the NL27WZ16MU2TCG variant in UDFN6-6 (1.2×1.0 mm) packaging.
Does the NL27WZ16MU2TCG support partial power-down functionality?
Yes, the NL27WZ16MU2TCG features IOFF circuitry that places all inputs and outputs in a high-impedance state when VCC = 0 V, preventing back-current flow and signal corruption during power sequencing. This behavior is explicitly specified in the datasheet's DC Electrical Characteristics table (IOFF ≤ 10 µA) and is inherent to the NL27WZ16MU2TCG silicon design.
Is the NL27WZ16MU2TCG pin-compatible with other packages in the NL27WZ16 family?
No - the NL27WZ16MU2TCG uses the UDFN6-6 (1.2×1.0 mm, 0.4 mm pitch) package with pin 1 rotated 180° clockwise, differing from SC-88 (MR code, Q4 orientation) and SC-74 (MR code, Q4 orientation) variants. Pin assignments match the UDFN6 layout shown in Figure 2 of the datasheet, but physical footprint and soldering requirements are not interchangeable.
What is the typical propagation delay of the NL27WZ16MU2TCG at 3.3 V supply?
At VCC = 3.3 V, RL = 1 MΩ, and CL = 15 pF, the NL27WZ16MU2TCG exhibits a typical propagation delay (tPLH/tPHL) of 2.3 ns, as specified in the AC Electrical Characteristics table (Rev. 13, May 2023). This value is measured across both channels and confirmed for the UDFN6 package variant.
Does the NL27WZ16MU2TCG require external pull-up or pull-down resistors on its inputs?
No - the NL27WZ16MU2TCG has no internal pull resistors and does not require external ones for basic operation. Input thresholds scale with VCC (e.g., VIH = 0.7×VCC min at ≥2.3 V), so clean logic-level signals within the recommended operating conditions will drive the device reliably without biasing components.
