Product details

Overview

NL27WZ02MU1TCG from onsemi is a dual 2-input NOR gate logic IC operating from 1.65 V to 5.5 V, delivering 2.5 ns typical propagation delay at 5 V, 24 mA output drive at 3.0 V, and overvoltage-tolerant inputs/outputs up to 5.5 V - used in level-shifting, signal inversion, and enable/disable control in portable and industrial digital systems.

For engineers reviewing the NL27WZ02MU1TCG datasheet, pinout, applications, or equivalent options, key selection criteria include supply voltage range (1.65–5.5 V), I_OFF partial power-down support, UDFN8-8 (1.95×1.0 mm) package footprint, and guaranteed operation across −55 °C to +125 °C.

Technical Context

The NL27WZ02MU1TCG implements two independent 2-input NOR gates with complementary CMOS architecture, supporting rail-to-rail input and output swing across its full 1.65–5.5 V V_CC range. Its I_OFF feature disables current flow when V_CC = 0 V, enabling live insertion and hot-swap compatibility in multi-rail systems.

Propagation delay varies with supply voltage and load: 1.9–3.1 ns (typ) at 4.5–5.5 V with 15 pF load, and 2.6–3.9 ns (typ) at 3.0–3.6 V under same conditions. Input thresholds scale with V_CC (VIH = 0.70×V_CC, VIL = 0.30×V_CC for V_CC ≥ 2.3 V), ensuring robust noise immunity across voltage domains.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CC Range	1.65 V to 5.5 V - supports single-supply operation across 1.8 V, 2.5 V, 3.3 V, and 5 V logic families
t_PD (typ)	2.5 ns at V_CC = 5 V, C_L = 15 pF - enables high-speed timing-critical combinational logic paths
I_OH/I_OL	±24 mA at V_CC = 3.0 V - drives multiple standard CMOS loads or interfaces directly with microcontroller GPIOs
Input Overvoltage Tolerance	Up to 5.5 V regardless of V_CC - allows safe interfacing with higher-voltage signals without external clamping
I_OFF	≤10 µA at V_CC = 0 V - prevents back-powering and signal contention during partial power-down states
Operating Temperature	−55 °C to +125 °C - qualified for automotive under-hood, industrial control, and extended-environment applications
Package	UDFN8-8, 1.95 mm × 1.0 mm, 0.5 mm pitch - ultra-compact footprint for space-constrained PCB layouts

Pinout & Package

NL27WZ02MU1TCG is housed in an 8-pin UDFN package (Case 517CA, 1.95×1.0 mm, 0.5 mm pitch) with wettable flank leads for automated optical inspection. Pin 1 is marked by a corner chamfer and located at top-left when the marking side faces up and the chamfer is oriented top-left.

Pin/Terminal	Circuit Role	Design Meaning
1	A1	First NOR gate input A - accepts 0–5.5 V logic levels independent of V_CC
2	B1	First NOR gate input B - enables dual-input logic evaluation with A1
3	Y2	Second NOR gate output - active-low result of A2 NOR B2
4	GND	Digital ground reference - must be low-impedance connection to system ground plane
5	A2	Second NOR gate input A - electrically isolated from A1/B1; supports independent logic function
6	B2	Second NOR gate input B - paired with A2 to form second 2-input NOR stage
7	Y1	First NOR gate output - active-low result of A1 NOR B1
8	V_CC	Positive supply - powers both gates; decoupling capacitor (0.1 µF) required within 2 mm

Key Features

Feature	Design Value
Rail-to-rail input tolerance	Inputs withstand up to 5.5 V regardless of V_CC level - eliminates need for external level translators in mixed-voltage systems
I_OFF protection	Sub-10 µA leakage when V_CC = 0 V - prevents bus contention and back-driving in hot-plug or partial-power-down scenarios
Low dynamic power	CPD = 11 pF at 5.5 V - minimizes switching current in battery-powered devices operating at 10 MHz
High-speed performance	3.1 ns max t_PD at 5 V - meets timing budgets for 100+ MHz clock domain gating and fast enable/disable sequencing
Pb-free & RoHS compliant	Halogen-free/BFR-free construction - satisfies IPC-J-STD-020 moisture sensitivity Level 1 and JEDEC reflow requirements

Applications

Power Sequencing Control	Level-Shifting Interface
Use Scenario: Coordinating startup order of multiple voltage rails (e.g., 1.8 V core before 3.3 V I/O) in FPGA or ASIC power management. IC Role / Device Role / Timing Role: NOR gate implements active-low enable logic that asserts downstream regulators only after all upstream supplies stabilize. Use Value: Eliminates discrete resistor-diode networks; leverages I_OFF to isolate unpowered rails during sequencing transitions.	Use Scenario: Interfacing a 5 V sensor output to a 3.3 V microcontroller input while maintaining logic compatibility. IC Role / Device Role / Timing Role: Configured as inverter (one input tied HIGH) to translate 5 V HIGH → 0 V LOW and 5 V LOW → 3.3 V HIGH. Use Value: Uses inherent 5.5 V input tolerance to accept 5 V signals directly - no external resistors or translators needed.
Industrial Sensor Signal Conditioning	Portable Device Reset Logic
Use Scenario: Combining fault signals from multiple temperature, pressure, and flow sensors into a single hardware shutdown line. IC Role / Device Role / Timing Role: Dual NOR gates perform OR-of-faults (via De Morgan: A NOR B = NOT(A OR B)) feeding a system reset controller. Use Value: Delivers sub-4 ns propagation at 3.3 V - ensures <100 ns fault response time critical for safety-critical industrial equipment.	Use Scenario: Generating a clean, debounced power-on reset pulse for Bluetooth SoCs in wearables and IoT edge nodes. IC Role / Device Role / Timing Role: One NOR gate combines RC-delayed V_CC ramp with manual reset button; second gate provides glitch-free output inversion. Use Value: Operates down to 1.65 V - guarantees reliable reset assertion during brown-out conditions common in coin-cell powered devices.

Equivalent & Alternatives

The following parts are listed as comparable options for similar dual 2-input NOR gate applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
SN74LVC2G02DPWR	Same UDFN8-8 package but rated only to 3.6 V V_CC; 3.7 ns t_PD (max) at 3.3 V; no I_OFF support	Lacks overvoltage tolerance and partial power-down - unsuitable for mixed-voltage or hot-swap systems	Select when operating strictly within 1.65–3.6 V and cost is primary driver
74AUP2G02GM,125	Smaller XSON8 (1.35×1.35 mm); 3.8 ns t_PD (max) at 3.3 V; supports 0.8–3.6 V V_CC; no overvoltage tolerance	Lower drive strength (±4 mA) and narrower voltage range - limited to ultra-low-power, single-rail designs	Select for space-constrained, battery-optimized designs where speed >4 ns is acceptable

Compared with SN74LVC2G02DPWR and 74AUP2G02GM,125, the NL27WZ02MU1TCG uniquely supports 5.5 V overvoltage tolerance, I_OFF-enabled partial power-down, and faster propagation (2.5 ns typ) across 1.65–5.5 V - making it the only choice for robust, multi-rail industrial and automotive signal conditioning.

FAQ

What is the maximum supply voltage rating for NL27WZ02MU1TCG?

The NL27WZ02MU1TCG has an absolute maximum DC supply voltage (V_CC) rating of +6.5 V, though recommended operation is limited to 1.65 V to 5.5 V per datasheet specifications. Exceeding 5.5 V may compromise long-term reliability even if functional at +6.5 V.

Does NL27WZ02MU1TCG support partial power-down mode?

Yes, NL27WZ02MU1TCG supports partial power-down via its I_OFF feature: when V_CC = 0 V, input/output leakage remains ≤10 µA, preventing back-current flow and enabling safe operation in systems where other rails remain active.

What is the pin 1 marking method for NL27WZ02MU1TCG's UDFN8 package?

NL27WZ02MU1TCG uses a corner chamfer to identify pin 1 - located at the top-left corner of the UDFN8 package (1.95×1.0 mm) when the device marking side faces upward and the chamfer aligns to the top-left.

Can NL27WZ02MU1TCG interface directly with 5 V logic while powered from 3.3 V?

Yes, NL27WZ02MU1TCG inputs tolerate up to 5.5 V regardless of V_CC level. When powered from 3.3 V, it safely accepts 5 V inputs and outputs 0 V / 3.3 V logic levels - enabling direct bridging between 5 V and 3.3 V domains without level shifters.

Is NL27WZ02MU1TCG suitable for automotive applications?

Yes, NL27WZ02MU1TCG is qualified for operation from −55 °C to +125 °C and features robust ESD protection (2000 V HBM), making it suitable for non-safety-critical automotive body electronics such as door modules, lighting controls, and HVAC interfaces.
