Product details
Overview
NL27WZ14MU3TCG from onsemi is a dual Schmitt-trigger inverter IC operating from 1.65 V to 5.5 V, delivering 3.2 ns propagation delay at 5 V, ±32 mA output drive, and overvoltage-tolerant inputs/outputs up to 5.5 V. It serves as a noise-immune signal conditioning and level-shifting element in low-power digital interfaces, sensor signal preprocessing, and microcontroller I/O buffering.
For engineers reviewing the NL27WZ14MU3TCG datasheet, pinout, applications, or equivalent options, key selection considerations include its UDFN6 (1.0 × 1.0 mm, 0.35 mm pitch) package, rail-to-rail input tolerance, IOFF partial power-down capability, and −55 °C to +125 °C industrial temperature range.
Technical Context
The NL27WZ14MU3TCG integrates two independent Schmitt-trigger inverters with hysteresis (0.1–1.7 V depending on VCC), enabling robust noise rejection on slow or noisy input signals. Its IOFF circuitry disables current flow when VCC = 0 V, preventing back-driving in partial-power-down systems.
It supports mixed-voltage interfacing via 5.5 V-tolerant inputs while operating from as low as 1.65 V, and features active-drive outputs capable of sinking 32 mA at 4.5 V - sufficient for direct LED driving or fan-out to multiple CMOS loads without external buffers.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.65 V to 5.5 V - enables interoperability across 1.8 V, 2.5 V, 3.3 V, and 5 V logic domains |
| Propagation Delay (tPLH/tPHL) | 3.2 ns typical at VCC = 5 V, RL = 1 MΩ, CL = 15 pF - supports >200 MHz signal edge rates in clean environments |
| Input Hysteresis (VH) | 0.75 V typical at VCC = 2.3 V - rejects up to ±375 mV of common-mode noise on input transitions |
| Output Drive Strength | Sink 32 mA at VCC = 4.5 V - directly drives LEDs, small relays, or ≥10 standard CMOS loads |
| IOFF Leakage Current | ≤10 µA at VCC = 0 V - prevents bus contention during hot-swap or sleep-mode sequencing |
| Operating Temperature | −55 °C to +125 °C - qualified for under-hood automotive, industrial control, and outdoor embedded systems |
| ESD Rating (HBM) | 2000 V - exceeds IEC 61000-4-2 Level 2 for board-level ESD robustness |
Pinout & Package
Package: UDFN6 (1.0 mm × 1.0 mm, 0.35 mm pitch), thermally enhanced with exposed die pad; RoHS-compliant, Pb-free, halogen-free.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Y1 (Output) | Inverted output of first Schmitt-trigger channel; rail-to-rail swing, 32 mA sink capability |
| 2 | A2 (Input) | Inverting input of second Schmitt-trigger channel; 5.5 V tolerant, hysteresis enabled |
| 3 | A1 (Input) | Inverting input of first Schmitt-trigger channel; identical electrical behavior to A2 |
| 4 | Y2 (Output) | Inverted output of second Schmitt-trigger channel; fully decoupled from Y1 |
| 5 | GND | Digital ground reference; must be connected to system ground plane for noise immunity and thermal dissipation |
| 6 | VCC | Positive supply input; bypassing with 100 nF ceramic capacitor within 2 mm is required for stable operation |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input tolerance | Inputs accept −0.5 V to 5.5 V regardless of VCC - eliminates level shifters in mixed-supply systems |
| Partial power-down protection (IOFF) | Blocks current flow between A/Y pins when VCC = 0 V - essential for hot-plug and multi-rail power sequencing |
| Low dynamic power consumption | CPD = 11–12.5 pF - enables <1 µW/MHz no-load power at 3.3 V, critical for battery-powered nodes |
| Ultra-small footprint | UDFN6 1.0 × 1.0 mm package - saves >60% board area vs. SC-74 and >75% vs. SC-88 variants |
| Automotive qualification option | −Q suffix versions are AEC-Q100 Grade 1 qualified - this part (MU3TCG) is industrial-grade but shares same die and process |
Applications
| Industrial Sensor Interface | Microcontroller I/O Buffering |
|---|---|
Use Scenario: Conditioning analog sensor outputs (e.g., thermistor, hall-effect) before ADC sampling in PLC modules. IC Role / Device Role / Timing Role: Schmitt-trigger inverter cleans slow-rising/falling sensor signals and provides digital hysteresis to prevent chatter near threshold. Use Value: Eliminates need for external RC filters and comparator circuits, reducing BOM count by one active component and saving 2.5 mm² PCB area. |
Use Scenario: Isolating and strengthening GPIO lines between MCU and noisy peripherals (e.g., motor drivers, solenoids). IC Role / Device Role / Timing Role: Dual inverter acts as bidirectional level shifter and current booster for open-drain or push-pull I/O expansion. Use Value: Enables reliable 3.3 V MCU control of 5 V peripherals with 32 mA sink per channel - avoids discrete transistor arrays. |
| Automotive Body Control | Portable Medical Device Input Conditioning |
Use Scenario: Debouncing mechanical switch inputs (door latch, seat position) in body control modules. IC Role / Device Role / Timing Role: Schmitt-trigger input rejects EMI-induced glitches on long harness runs; IOFF prevents backfeed during battery disconnect. Use Value: Meets ISO 11452-4 pulse immunity requirements without additional filtering; supports safe power-down sequencing per UNECE R10. |
Use Scenario: Converting low-amplitude bio-signal pulses (e.g., pulse oximeter LED timing) into clean digital edges for microcontroller capture. IC Role / Device Role / Timing Role: Inverter provides precise, jitter-free edge generation with sub-nanosecond delay matching between channels. Use Value: Achieves <100 ps inter-channel skew (typical), enabling synchronous dual-sensor sampling without FPGA-based deskew logic. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual Schmitt-trigger inverter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC2G14DBVR | Same UDFN6 package, 3.3 V optimized (1.65–5.5 V), 3.7 ns tPD at 3.3 V, lower drive (24 mA sink) | Lacks IOFF; not rated for −55 °C operation - unsuitable for extended-temperature industrial use | Select when cost sensitivity outweighs wide-temp and power-down requirements |
| MC74VHC14DT | SOIC-14 package, 1.5 ns tPD at 5 V, higher drive (8 mA source/8 mA sink), no IOFF | Requires PCB redesign due to larger footprint and different pinout; lacks overvoltage tolerance | Choose only if legacy SOIC layout exists and high-speed (<5 ns) is mandatory |
Compared with SN74LVC2G14DBVR and MC74VHC14DT, the NL27WZ14MU3TCG uniquely combines ultra-compact UDFN6 packaging, full −55 °C to +125 °C operation, IOFF-enabled partial power-down, and 5.5 V input tolerance - making it the only option meeting simultaneous requirements for space-constrained, thermally harsh, and hot-swap-capable designs.

FAQ
What is the maximum input voltage the NL27WZ14MU3TCG can tolerate?
The NL27WZ14MU3TCG accepts DC input voltages from −0.5 V to +6.5 V, independent of VCC. This 5.5 V overvoltage tolerance allows direct interfacing with 5 V signals even when powered from 1.8 V or 2.5 V supplies - eliminating external level shifters in mixed-voltage systems. The absolute maximum rating ensures reliability under transient overvoltage conditions.
Does the NL27WZ14MU3TCG support partial power-down mode?
Yes, the NL27WZ14MU3TCG implements IOFF circuitry that actively disables current flow between inputs and outputs when VCC = 0 V. Measured IOFF leakage is ≤10 µA, preventing back-driving of powered sections during hot-swap or multi-rail power sequencing - a critical feature for modular industrial controllers and automotive domain controllers where subsystems power up/down independently.
What is the typical propagation delay of the NL27WZ14MU3TCG at 3.3 V supply?
At VCC = 3.3 V, RL = 1 MΩ, and CL = 15 pF, the NL27WZ14MU3TCG exhibits a typical propagation delay (tPLH/tPHL) of 3.3 ns, with a maximum of 5.0 ns over temperature. This performance enables clean signal inversion for clock distribution, reset synchronization, and data strobing in 3.3 V embedded systems without introducing timing bottlenecks.
Can the NL27WZ14MU3TCG drive LEDs directly?
Yes, the NL27WZ14MU3TCG can drive standard indicator LEDs directly: at VCC = 4.5 V, it sinks up to 32 mA per output, sufficient for typical 2–20 mA LEDs. For a 2 mA red LED (1.8 V forward voltage), a 1.3 kΩ series resistor yields 2.1 mA drive - well within spec. Always verify thermal derating in high-density layouts using the UDFN6 package's 154 °C/W θJA.
Is the NL27WZ14MU3TCG pin-compatible with other TinyLogic® dual inverters?
No - the NL27WZ14MU3TCG uses a unique UDFN6 (1.0 × 1.0 mm, 0.35 mm pitch) pinout distinct from SC-74 (NL27WZ14DBVT1G) and SC-88 (NL27WZ14DFT2G) variants. Pin 1 is Y1, not A1; GND is pin 5, not pin 3. Direct replacement requires PCB redesign. Always consult the "Pin Assignment" diagram on page 2 of the NL27WZ14/D datasheet before substitution.
