Product details
Overview
NC7SZ02FHX from ON Semiconductor is a single two-input NOR gate in the TinyLogic® UHS family, designed for ultra-high-speed logic level translation and signal conditioning in space-constrained digital systems. It operates across 1.65V–5.5V VCC, delivers 2.4ns typical propagation delay into 50pF at 5V, and provides ±24mA output drive at 3V - enabling use in mixed-voltage I/O buffering and battery-powered interface circuits.
For engineers reviewing the NC7SZ02FHX datasheet, pinout, applications, or equivalent options, key selection considerations include its MicroPak2™ 6-lead 1×1mm package, over-voltage tolerant inputs (up to 6V), power-down high-impedance behavior, and compatibility with 1.8V/2.5V/3.3V/5V logic families.
Technical Context
The NC7SZ02FHX implements a CMOS-based NOR logic function with true complementary output stage, supporting rail-to-rail input voltage tolerance independent of VCC. Its propagation delay scales predictably with supply voltage and load capacitance - e.g., 2.3ns typical at 3.3V/50pF and 1.9ns at 5V/50pF - making it suitable for timing-critical glue logic.
Input thresholds are VIL ≤ 0.30VCC and VIH ≥ 0.70VCC across 2.3V–5.5V VCC, ensuring noise margin compliance in noisy environments. The device enters high-impedance state on all pins when VCC = 0V, eliminating leakage paths during power sequencing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 1.65V to 5.5V - supports direct interfacing between 1.8V, 2.5V, 3.3V, and 5V logic domains without level shifters. |
| tPD (Typ.) | 2.4ns into 50pF at 5V - enables sub-400MHz toggle rates in low-capacitance routing scenarios. |
| IOH/IOL | ±24mA at 3V VCC - drives multiple standard CMOS loads or small capacitive traces without external buffers. |
| VIN Tolerance | −0.5V to 6.0V - allows safe 5V-tolerant inputs even when powered from 1.8V or 2.5V supplies. |
| Power-Down State | All I/Os high-impedance when VCC = 0V - prevents back-powering and ensures clean power sequencing in multi-rail systems. |
| IIN Leakage | ±10µA max at VIN = 5.5V - minimizes standby current in always-on monitoring nodes. |
Pinout & Package
NC7SZ02FHX uses the MicroPak2™ 6-lead package (1.0mm × 1.0mm body, 0.35mm pitch), optimized for ultra-dense PCB layouts and reflow-compatible assembly. Its leadless design requires solder paste volume control and X-ray inspection for void detection.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | A | First logic input - accepts voltages up to 6V regardless of VCC; must be tied HIGH or LOW (no floating). |
| 2 | B | Second logic input - identical electrical characteristics to Pin 1; shares same over-voltage tolerance and threshold behavior. |
| 3 | GND | Ground reference - connects to system ground plane; decoupling capacitor (0.1µF) recommended within 2mm. |
| 4 | Y | NOR output - actively drives HIGH/LOW with ±24mA capability at 3V; open-drain operation not supported. |
| 5 | NC | No connect - internally unconnected; must remain unpopulated on PCB land pattern to avoid parasitic coupling. |
| 6 | VCC | Supply voltage - accepts 1.65V–5.5V; bypass capacitor required adjacent to this pin for stable high-speed switching. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-High Speed | 2.4ns typical propagation delay at 5V/50pF - reduces combinatorial path delay in FPGA/CPLD interface logic. |
| High Output Drive | ±24mA sink/source at 3V - eliminates need for discrete buffer stages in driving LED indicators or small-signal relays. |
| Over-Voltage Tolerant Inputs | Inputs withstand −0.5V to +6.0V - enables robust 5V-to-3.3V translation without external resistors or clamps. |
| Power-Down High-Z | All I/Os enter high-impedance when VCC = 0V - prevents current backflow during hot-swap or partial power-down sequences. |
| EMI Reduction Circuitry | Proprietary slew-rate control - limits edge-induced radiated emissions in EMC-sensitive consumer and industrial designs. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar two-input NOR gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC1G02DBVR | Same 5-pin SOT-23 package; 3.3V-only VCC range (1.65V–5.5V); 3.7ns tPD typical at 3.3V/50pF. | Lacks 6V input tolerance; requires external clamping for 5V signal interfacing. | Preferred when board space permits SOT-23 and system uses only 3.3V logic rails. |
| 74AUP1G02GW,125 | 5-pin SC-70 package; 0.8V–3.6V VCC range; 2.3ns tPD typical at 3.3V/50pF; 4µA ICC max. | Lower drive strength (±4mA); incompatible with 5V inputs without translation. | Optimal for ultra-low-power IoT nodes where 5V tolerance is unnecessary and <1µA sleep current is critical. |
Compared with SN74LVC1G02DBVR and 74AUP1G02GW,125, the NC7SZ02FHX uniquely combines 6V input tolerance, 1×1mm MicroPak2™ footprint, and ±24mA drive - making it the only option supporting direct 5V-to-1.8V translation in sub-1mm² area-constrained designs.

FAQ
What is the maximum input voltage rating for NC7SZ02FHX?
The NC7SZ02FHX supports DC input voltages from −0.5V to +6.0V, independent of VCC level. This over-voltage tolerance enables safe interfacing with 5V signals even when the device is powered from 1.8V or 2.5V supplies - a key advantage over standard LVC or AUP-series gates that lack this feature. Always ensure input current remains within ±20mA per Absolute Maximum Ratings.
Does NC7SZ02FHX support power-down mode with high-impedance I/Os?
Yes, the NC7SZ02FHX enters a true power-down state when VCC = 0V: all inputs and outputs become high-impedance, preventing back-current flow and ensuring clean power sequencing in multi-rail systems. This behavior is confirmed in the datasheet's "Description" section and validated across −40°C to +85°C operating temperature range.
What is the typical propagation delay of NC7SZ02FHX at 3.3V supply?
At 3.3V VCC with 50pF load and 500Ω termination, the NC7SZ02FHX exhibits 2.3ns typical propagation delay (tPLH/tPHL). This value is measured under controlled AC test conditions (Figure 5 in datasheet Rev. 1.0.5) and scales predictably with supply voltage - e.g., 2.9ns at 2.5V and 4.5ns at 1.8V under same load.
Can NC7SZ02FHX drive multiple 74LVC inputs directly?
Yes, the NC7SZ02FHX can drive up to eight 74LVC-series inputs at 3.3V VCC, based on its ±24mA output drive capability and typical 74LVC input current of ±1µA. At 5V VCC, it supports up to ten 74HC inputs. Load calculations must account for total capacitive loading (≤50pF recommended) to maintain specified tPD performance.
Is the NC7SZ02FHX pinout compatible with other TinyLogic® NOR gates in MicroPak2™ packages?
Yes, the NC7SZ02FHX shares identical pinout (A/B/GND/Y/NC/VCC) and MicroPak2™ 6-lead footprint with other TinyLogic® UHS NOR variants like NC7SZ04FHX and NC7SZ14FHX. This allows drop-in replacement for functional upgrades (e.g., inverter → NOR) without PCB redesign - provided the logic function change is validated in system-level timing analysis.
