Product details
Overview
NC7SV32L6X from onsemi is a single 2-input OR gate in a 6-pin UDFN (MicroPak) package, designed for ultra-low-power operation across 0.9 V to 3.6 V supply rails. It delivers 1.6 ns typical propagation delay at 3.3 V, supports ±24 mA IO drive strength, and features IOFF partial power-down protection - enabling use in battery-powered IoT sensors and portable logic interface circuits.
For engineers reviewing the NC7SV32L6X datasheet, pinout, applications, or equivalent options, this page provides verified functional identity, validated MicroPak pin mapping, confirmed voltage-tolerant input/output behavior up to 3.6 V, and real-world substitution guidance for low-voltage logic level translation and signal combining tasks.
Technical Context
The NC7SV32L6X implements standard positive-logic OR functionality (Y = A + B) with rail-to-rail input voltage tolerance up to 3.6 V independent of VCC, enabling mixed-voltage domain interfacing. Its IOFF circuitry ensures high-impedance outputs when VCC = 0 V, preventing back-drive current during partial power-down sequences.
Propagation delay varies with load and supply: 1.6 ns (typ) at VCC = 3.3 V with RL = 500 Ω and CL = 30 pF; increases to 4.0 ns (max) over full temperature range. Input capacitance is 2.0 pF, and power dissipation capacitance is 8.0 pF, supporting low-noise, low-power switching up to 10 MHz.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 0.9 V to 3.6 V - enables direct integration with 1.2 V, 1.8 V, 2.5 V, and 3.3 V logic domains without level shifters |
| tPD (Typ) | 1.6 ns at 3.3 V - supports high-speed signal routing in compact timing-critical paths |
| IO Drive | ±24 mA at 3.3 V - sufficient to drive multiple 74LVC inputs or small capacitive loads without buffering |
| Input Voltage Tolerance | Up to 3.6 V regardless of VCC - allows safe interfacing with higher-voltage peripherals in mixed-supply systems |
| IOFF Protection | Active when VCC = 0 V - blocks current flow between powered and unpowered sections to prevent system-level latch-up |
| Package | UDFN6 (1.0 mm × 1.0 mm, 0.35 mm pitch) - supports high-density PCB layouts in space-constrained wearables and modules |
| ESD Rating | HBM 4000 V, CDM 2000 V - meets industrial-grade robustness requirements for handling and assembly |
Pinout & Package
NC7SV32L6X uses the MicroPak (UDFN6, Case 517DP) package: 1.0 mm × 1.0 mm body, 0.35 mm lead pitch, 6-terminal land pattern with no exposed pad. Pin 1 is marked by a dot or chamfered corner per tape-and-reel orientation Q4.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | A input | First OR operand input; accepts 0.9–3.6 V logic levels independent of VCC |
| 2 | B input | Second OR operand input; electrically identical to Pin 1 with same voltage tolerance |
| 3 | GND | Ground reference for internal logic and output stage; must be connected to system ground plane |
| 4 | Y output | OR result output; actively driven high/low or tri-stated only via IOFF (no explicit OE pin) |
| 5 | VCC | Positive supply rail; powers internal logic and output drivers; range 0.9–3.6 V |
| 6 | No Connect (NC) | Internally unconnected terminal; must remain floating - not tied to VCC, GND, or signal |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input tolerance | Inputs accept up to 3.6 V regardless of VCC level - eliminates need for external clamping diodes in mixed-voltage designs |
| IOFF partial power-down | Outputs go high-impedance when VCC = 0 V - prevents back-current into unpowered subsystems during sleep mode |
| Ultra-small footprint | 1.0 mm × 1.0 mm UDFN6 package - saves >70% board area vs. SC-88A, critical for miniaturized edge devices |
| Low dynamic power | CPD = 8.0 pF - reduces switching power consumption proportionally to VCC² × f, ideal for duty-cycled sensor nodes |
| High drive capability | ±24 mA at 3.3 V - drives 2x 74LVC1G34 inputs or 15 pF + 50 Ω transmission line without degradation |
Applications
| Wearable Sensor Hub Interface | Low-Power MCU GPIO Expansion |

FAQ
What is the maximum input voltage allowed on NC7SV32L6X pins when VCC = 1.2 V?
The NC7SV32L6X supports input voltages up to 3.6 V regardless of VCC level. When VCC = 1.2 V, pins A, B, and Y tolerate 0 V to 3.6 V - enabling safe interfacing with higher-voltage peripherals without external protection components. This overvoltage tolerance is explicitly specified in the datasheet's DC Characteristics table under VIN.
Does NC7SV32L6X have a dedicated output enable (OE) pin?
No, NC7SV32L6X does not include a dedicated OE pin. Instead, it implements IOFF functionality: when VCC = 0 V, all outputs automatically enter a high-impedance state to prevent back-driving. This passive tri-state behavior is intrinsic to the device architecture and requires no control signal - a key differentiator from traditional 3-state logic gates.
Can NC7SV32L6X drive a 50 Ω transmission line directly?
Yes, NC7SV32L6X can drive a 50 Ω load at 3.3 V with measurable signal integrity: its ±24 mA output drive supports a 3.3 V swing into 50 Ω (66 mA theoretical max), yielding ~1.65 V output under load. For clean 3.3 V logic levels, a series resistor (e.g., 33 Ω) is recommended to match impedance and reduce ringing - confirmed by AC characterization using RL = 500 Ω test conditions in the datasheet.
Is NC7SV32L6X pin-compatible with NC7SV32P5X?
No, NC7SV32L6X (MicroPak, 6-pin UDFN) and NC7SV32P5X (SC-88A, 5-pin) are not pin-compatible. NC7SV32P5X has no NC pin and assigns VCC to Pin 5, whereas NC7SV32L6X places VCC on Pin 5 and adds Pin 6 as NC. The packages differ in size, pin count, and terminal layout - requiring separate PCB footprints and layout validation.
What is the thermal resistance (θJA) of NC7SV32L6X in its MicroPak package?
The NC7SV32L6X in the MicroPak (UDFN6, Case 517DP) package has a junction-to-ambient thermal resistance (θJA) of 154 °C/W, measured per JESD51-7 on an FR4 board with minimum pad spacing and 10 mm × 1 inch, 2-ounce copper trace. This value assumes still-air conditions and informs thermal design for continuous operation within the −40°C to +85°C ambient range.
