Product details
Overview
74HC2G32DC,125 from Nexperia is a dual 2-input OR gate logic IC in VSSOP8 package, operating from 2.0 V to 6.0 V supply, with CMOS-level inputs, propagation delay of 9.0 ns (typ) at 4.5 V, and guaranteed operation from –40 °C to +125 °C. It integrates two independent OR functions with input clamp diodes enabling safe interfacing to voltages exceeding VCC in industrial control signal conditioning.
For engineers reviewing the 74HC2G32DC,125 datasheet, 74HC2G32DC,125 pinout, 74HC2G32DC,125 application, or 74HC2G32DC,125 equivalent, this device serves as a low-power, high-noise-immunity combinational logic building block for level translation, bus arbitration, and enable logic in space-constrained embedded systems requiring stable timing behavior and rail-to-rail input tolerance.
Technical Context
This device implements two independent 2-input OR gates using standard CMOS technology. Each gate features input clamp diodes for overvoltage protection and supports TTL-compatible input thresholds only in the HCT variant - the 74HC2G32DC uses pure CMOS input levels (VIH = 0.7×VCC, VIL = 0.3×VCC). The logic function follows strict Boolean OR behavior per Table 4: output is HIGH if either input is HIGH.
It operates within JEDEC JESD7A-compliant voltage ranges and meets ANSI/ESDA/JEDEC JS-001 Class 2 (2000 V HBM) and JS-002 Class C3 (1000 V CDM) ESD ratings. Latch-up immunity exceeds 100 mA per JESD78 Class II Level B, ensuring robustness in noisy industrial environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Function | Dual independent 2-input OR gate; outputs HIGH when ≥1 input is HIGH - enables basic decision logic without external pull-ups. |
| Supply Voltage Range | 2.0 V to 6.0 V - supports direct interface with 3.3 V and 5 V systems, including mixed-voltage board designs. |
| Propagation Delay | 9.0 ns (typ) at VCC = 4.5 V - ensures sub-10 ns combinatorial response for real-time signal merging in control paths. |
| Input Clamp Diodes | Integrated on all inputs - allows use of current-limiting resistors to safely interface to signals up to VCC + 0.5 V, simplifying level-shifting circuits. |
| Operating Temperature | –40 °C to +125 °C - qualified for under-hood automotive modules, motor drives, and industrial PLC I/O stages. |
| Static Power Dissipation | ≤1.0 μA ICC (max) at VCC = 6.0 V - enables ultra-low quiescent current in battery-backed or always-on monitoring nodes. |
| Output Drive | ±4.0 mA at VCC = 4.5 V - sufficient to drive 10 LS-TTL loads or directly fan out to multiple CMOS inputs without buffering. |
Pinout & Package
VSSOP8 plastic very thin shrink small outline package (SOT765-1); 8 leads; body width 2.3 mm; pin 1 indicator located below marking code in lower-left corner.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 1A | First OR gate input A - accepts CMOS-level signals; clamped to protect against overvoltage. |
| 2 | 1B | First OR gate input B - paired with 1A; both inputs must be LOW for 1Y to be LOW. |
| 3 | 1Y | First OR gate output - active-HIGH, open-drain capable only when externally pulled; drives downstream logic directly. |
| 4 | GND | Ground reference (0 V) - mandatory return path for all internal currents and noise filtering. |
| 5 | 2A | Second OR gate input A - electrically isolated from first gate; enables independent logic paths in same footprint. |
| 6 | 2B | Second OR gate input B - identical electrical characteristics to 1A/1B; supports parallel OR operations. |
| 7 | 2Y | Second OR gate output - matches 1Y timing and drive strength; allows dual-channel signal combination. |
| 8 | VCC | Positive supply rail - powers both gates; decoupling capacitor required within 1 cm for stable switching. |
Key Features
| Feature | Design Value |
|---|---|
| Wide supply range (2.0–6.0 V) | Eliminates need for separate voltage translators when interfacing 3.3 V controllers to 5 V peripherals. |
| CMOS-level input thresholds | Ensures predictable switching at 70 % VCC (VIH) and 30 % VCC (VIL), reducing false triggering in noisy analog-adjacent layouts. |
| Input clamp diodes | Permits direct connection to 12 V sensor outputs via series resistor - no external protection diodes required. |
| High noise immunity | Typical noise margin >1.2 V at 4.5 V supply - suppresses coupling from adjacent switching regulators or motor drivers. |
| Latch-up immunity >100 mA | Withstands transient ground bounce or ESD-induced substrate currents without functional interruption or damage. |
Applications
| Industrial Sensor Interface | Microcontroller GPIO Expansion |
|---|---|
Use Scenario: Combining fault signals from multiple temperature sensors in a motor drive cabinet where any single overtemperature event must trigger immediate shutdown. IC Role / Device Role / Timing Role: Dual OR gate performs wired-OR aggregation of three independent sensor alerts into two consolidated alarm lines routed to MCU interrupt pins. Use Value: Reduces PCB routing complexity by replacing discrete diode-OR networks; maintains nanosecond-level response critical for thermal runaway prevention. |
Use Scenario: Extending limited GPIO count on an ARM Cortex-M0+ microcontroller to manage eight discrete enable signals for peripheral power rails. IC Role / Device Role / Timing Role: Two OR gates merge pairs of MCU output pins (e.g., EN_A1/EN_A2 → EN_A) to generate composite enable commands with deterministic setup/hold timing. Use Value: Enables precise sequencing control without firmware overhead or additional microcontroller resources - each OR output settles within 9 ns. |
| Legacy Bus Arbitration | Power Sequencing Monitor |
Use Scenario: Resolving bus grant requests from two legacy ISA-style expansion cards competing for shared memory-mapped I/O access. IC Role / Device Role / Timing Role: Acts as priority-agnostic OR node feeding a central arbiter; ensures grant signal asserts immediately upon either card's request. Use Value: Guarantees sub-10 ns resolution latency - faster than typical ISA bus cycle timing - preventing bus contention lockup. |
Use Scenario: Validating correct power-up order across three regulated rails (1.2 V, 3.3 V, 5.0 V) in an FPGA-based imaging module before releasing reset. IC Role / Device Role / Timing Role: Each OR gate monitors pair of rail-good signals (e.g., 1.2V_OK OR 3.3V_OK); final output enables FPGA configuration only when all are asserted. Use Value: Provides hardware-enforced sequencing with zero software dependency - eliminates risk of FPGA configuration failure due to premature release. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual 2-input OR gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 74HCT2G32DC,125 | TTL-compatible inputs (VIH = 2.0 V min), otherwise identical pinout, timing, and package. | Required when interfacing with legacy 5 V TTL outputs lacking CMOS voltage swing. | Select when driving from 74LS or older microcontrollers with weak HIGH-level drive capability. |
| SN74LVC2G32DCKR | Narrower supply range (1.65–5.5 V), slightly faster tpd (5.5 ns typ @ 3.3 V), same VSSOP8 footprint. | Better suited for 1.8 V/3.3 V-only systems; lacks clamp diodes - requires external protection for overvoltage inputs. | Choose for low-voltage portable designs where speed matters more than input overvoltage tolerance. |
Compared with 74HC2G32DC,125, the 74HCT2G32DC,125 offers guaranteed TTL input compatibility at the cost of reduced noise margin, while SN74LVC2G32DCKR delivers higher speed in 3.3 V domains but removes integrated input clamping - making the HC variant optimal for mixed-voltage industrial interfaces requiring robustness.

FAQ
What is the maximum clock frequency supported by the 74HC2G32DC,125?
The 74HC2G32DC,125 is a combinational logic gate-not a clocked device-so it has no defined clock frequency. Its usable signal switching rate is determined by propagation delay (9.0 ns typ at 4.5 V) and transition time (6 ns typ), supporting data rates up to ~55 MHz in repetitive OR operations with clean edges and proper load capacitance.
Can the 74HC2G32DC,125 drive LEDs directly?
No. Its output drive capability is ±4.0 mA at 4.5 V, insufficient for typical indicator LEDs requiring 5–20 mA. It can drive LED cathodes only with external current-limiting resistors and a pull-up to VCC, but sustained DC loading risks exceeding IO absolute maximum ratings; dedicated LED drivers or buffer stages are recommended.
Does the 74HC2G32DC,125 support partial power-down or Ioff protection?
No. This device lacks Ioff (power-off protection) circuitry. When VCC = 0 V, inputs and outputs may sink or source current if external voltages are applied - potentially damaging the IC or disturbing other circuit nodes. Always power VCC before applying input signals in hot-swap or multi-rail systems.
How does the input clamp diode affect design with 12 V sensors?
The integrated clamp diodes allow safe interface to 12 V signals using a single series current-limiting resistor (e.g., 10 kΩ limits IVCC to <1.2 mA at 12 V). This eliminates external diodes and saves board space, but resistor value must ensure input current stays within ±20 mA absolute maximum rating per pin.
