Product details
Overview
NC7SZ32M5X-L22090 from onsemi is a single two-input OR gate in the TinyLogic UHS family, designed for high-speed logic level translation and signal combining in space-constrained digital systems. It operates across 1.65 V to 5.5 V VCC, delivers 2.4 ns typical propagation delay at 5 V into 50 pF, and provides ±24 mA output drive at 3 V - enabling direct interface with legacy 5 V and modern 1.8/2.5/3.3 V logic domains in portable and industrial control applications.
For engineers reviewing the NC7SZ32M5X-L22090 datasheet, pinout, applications, or equivalent options, key selection criteria include its ultra-small SOT23-5 package, over-voltage tolerant inputs (up to 5.5 V independent of VCC), power-down high-impedance I/O, and guaranteed operation from −40 °C to +85 °C.
Technical Context
The NC7SZ32M5X-L22090 implements standard positive-logic OR functionality (Y = A + B) using advanced CMOS process technology optimized for speed-power trade-off. Its input structure supports voltage-level translation between 5 V and lower-VCC systems without external biasing, and its outputs are fully specified for driving capacitive loads up to 50 pF with sub-5 ns delay at 3.3 V and 5 V.
It features proprietary noise/EMI reduction circuitry and exhibits rail-to-rail output swing under load. Inputs remain high-impedance when VCC = 0 V, and all I/O tolerate 5.5 V regardless of supply voltage - critical for mixed-supply system interoperability and hot-swap compatibility.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 1.65 V to 5.5 V - enables single-device support across 1.8 V, 2.5 V, 3.3 V, and 5 V logic families |
| tPD (Typ) | 2.4 ns at VCC = 3.3 V, CL = 50 pF - ensures timing-critical path compatibility in high-frequency control logic |
| IOH/IOL | ±24 mA at VCC = 3 V - drives multiple LS-TTL or CMOS inputs without buffering |
| Input Voltage Tolerance | Up to 5.5 V independent of VCC - eliminates level-shifter ICs in 5 V → 3.3 V translation |
| Operating Temperature | −40 °C to +85 °C - qualified for industrial-grade embedded and automotive cabin electronics |
| Power-Down Behavior | Inputs and outputs go high-impedance when VCC = 0 V - prevents back-driving during partial power-down |
Pinout & Package
NC7SZ32M5X-L22090 is packaged in a Pb-free, RoHS-compliant SOT23-5 (Case 527AH) surface-mount package measuring 3.00 mm × 1.50 mm × 0.95 mm with 0.95 mm lead pitch.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | A | Primary logic input; accepts 0–5.5 V signals regardless of VCC value |
| 2 | B | Secondary logic input; electrically identical to Pin 1 with same voltage tolerance |
| 3 | GND | Ground reference for logic thresholds and output drive; must be low-impedance |
| 4 | Y | OR output; rail-to-rail swing, capable of sourcing/sinking ±24 mA at 3 V |
| 5 | VCC | Positive supply; powers internal logic and output stage; range 1.65–5.5 V |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-High Speed | 2.4 ns typical propagation delay at 3.3 V enables use in >200 MHz clock-domain boundary logic |
| Over-Voltage Tolerant Inputs | Accepts 5.5 V inputs even at VCC = 1.65 V - simplifies inter-voltage-domain signal routing |
| High Output Drive | ±24 mA at 3 V supports fan-out of ≥10 74LVC inputs or direct LED drive with current-limiting resistor |
| Power-Down High-Z I/O | Entire device enters tri-state when VCC = 0 V - prevents bus contention during power sequencing |
| Pb-Free & RoHS Compliant | SOT23-5 package meets IPC/JEDEC J-STD-020 moisture sensitivity level 1 (MSL1) for reflow |
Applications
| Industrial PLC I/O Expansion | Portable Device Power Sequencing |
|---|---|
Use Scenario: Combining multiple sensor fault signals into a single hardware interrupt line feeding a microcontroller. IC Role / Device Role / Timing Role: Single-gate OR function aggregating asynchronous digital status flags with minimal propagation delay. Use Value: Eliminates need for larger logic arrays or software polling; 2.4 ns delay ensures deterministic response within real-time control cycles. | Use Scenario: Enabling subsystem power rails only after primary voltage and enable signals are both asserted. IC Role / Device Role / Timing Role: Active-high OR gate generating combined "power-good" signal from redundant sources. Use Value: Guarantees fast, glitch-free power-enable assertion with no external pull-ups or timing components required. |
| USB-C Port Controller Logic | Automotive Body Control Module |
Use Scenario: Merging CC1/CC2 connector detection signals to trigger USB PD negotiation state machine. IC Role / Device Role / Timing Role: Level-translating OR gate interfacing 5 V CC-line sensing with 3.3 V controller GPIO. Use Value: Over-voltage tolerant inputs accept 5 V CC-line voltages directly while powered from 3.3 V rail - no external level shifter needed. | Use Scenario: Consolidating door-open, seat-belt, and ignition status into a single wake-up request for low-power MCU sleep mode. IC Role / Device Role / Timing Role: Low-quiescent-current OR gate operating across automotive temperature range (−40 °C to +85 °C). Use Value: 2.0 µA max ICC enables always-on monitoring without battery drain; SOT23-5 footprint saves PCB area in tight BCM layouts. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar OR gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC1G32DBVR | Same SOT23-5 package; tPD = 3.7 ns (typ) at 3.3 V, 50 pF; input tolerance limited to VCC + 0.5 V | Not suitable for 5 V → 3.3 V translation without external clamping | Select when cost sensitivity outweighs speed and level-translation requirements |
| 74AUP1G32GW,125 | SC-70-5 package; tPD = 2.3 ns (typ) at 3.3 V; VCC range 0.8–3.6 V only; no 5.5 V input tolerance | Cannot interface with 5 V signals; requires separate level-shifting for mixed-supply designs | Prefer for ultra-low-power (<1 µA ICC) applications where supply is strictly ≤3.6 V |
Compared with SN74LVC1G32DBVR and 74AUP1G32GW,125, the NC7SZ32M5X-L22090 uniquely combines 2.4 ns speed, 1.65–5.5 V operation, and 5.5 V input tolerance in SOT23-5 - making it the only option among the three that supports direct 5 V signal injection into sub-2 V logic domains without external components.

FAQ
What is the maximum input voltage rating for NC7SZ32M5X-L22090?
The NC7SZ32M5X-L22090 supports DC input voltages up to 5.5 V on pins A, B, and Y - independent of the VCC supply voltage. This allows safe interfacing with 5 V signals even when powered from 1.65 V, eliminating external level shifters in mixed-voltage systems. Absolute maximum rating is 6.5 V, but functional operation is guaranteed only to 5.5 V per datasheet specifications.
Does NC7SZ32M5X-L22090 support power-down mode?
Yes, the NC7SZ32M5X-L22090 enters a true high-impedance state when VCC = 0 V: both inputs and output become high-impedance, preventing back-driving or leakage paths. This behavior is explicitly characterized in the datasheet under "Power Down High-Impedance Inputs / Outputs" and supports robust power sequencing in multi-rail systems where subsystems power up/down asynchronously.
What is the propagation delay of NC7SZ32M5X-L22090 at 1.8 V supply?
At VCC = 1.8 V and CL = 15 pF, the NC7SZ32M5X-L22090 has a typical propagation delay (tPLH/tPHL) of 4.6 ns and a maximum of 10.5 ns over temperature. This is confirmed in the AC Electrical Characteristics table (page 5 of datasheet Rev. 8), where delay is specified across the full 1.65–5.5 V range with load and temperature conditions clearly defined.
Is NC7SZ32M5X-L22090 pin-compatible with other TinyLogic OR gates in SOT23-5?
Yes, the NC7SZ32M5X-L22090 shares identical pinout (A-B-GND-Y-VCC) with other SOT23-5 TinyLogic OR gates including NC7SZ32M5X (base part) and NC7SZ02M5X (NOR variant). This allows drop-in replacement within the same package family for functional redesigns, provided timing and drive requirements remain compatible - verified via Figure 2 and Pin Definitions table in the datasheet.
What is the thermal resistance (θJA) of NC7SZ32M5X-L22090 in its SOT23-5 package?
The NC7SZ32M5X-L22090 in SOT23-5 (Case 527AH) has a junction-to-ambient thermal resistance (θJA) of 320 °C/W under standard JEDEC test conditions. This value is specified in the Recommended Operating Conditions table (page 3) and reflects performance on a 1-inch² copper pad with 2 oz Cu; actual board-level θJA will improve with enhanced copper pour and thermal vias.
