Product details
Overview
74AHC2G32DP,125 from Nexperia is a dual 2-input OR gate logic IC in TSSOP8 package, operating from 2.0 V to 5.5 V supply, with overvoltage-tolerant inputs up to 5.5 V, CMOS input levels, and guaranteed operation from –40 °C to +125 °C - used for level translation and combinatorial logic in mixed-voltage digital interfaces.
For engineers reviewing the 74AHC2G32DP,125 datasheet, 74AHC2G32DP,125 pinout, 74AHC2G32DP,125 application, or 74AHC2G32DP,125 equivalent, this device supports voltage-level bridging between 3.3 V and 5 V domains, delivers symmetrical output drive (±8 mA), and maintains low propagation delay (3.2 ns typical at 5 V/15 pF) with high noise immunity in space-constrained industrial control and sensor interface designs.
Technical Context
The 74AHC2G32DP,125 implements two independent OR gates with true TTL-compatible output characteristics and CMOS input thresholds. Its overvoltage-tolerant inputs enable direct connection to 5.5 V signals while powered from as low as 2.0 V, eliminating external level-shifting components.
It features balanced rise/fall times, latch-up immunity exceeding 100 mA per JESD78 Class II Level A, and ESD protection rated at >2000 V HBM and >1000 V CDM - ensuring robustness in noisy industrial environments and hot-swap-capable subsystems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.0 V to 5.5 V - enables single-supply operation across 2.5 V, 3.3 V, and 5 V logic domains without level shifters. |
| Input Voltage Tolerance | Up to 5.5 V independent of VCC - allows safe interfacing with higher-voltage peripherals while powered at lower rail. |
| Propagation Delay (tpd) | 3.2 ns typical at VCC = 5.0 V, CL = 15 pF - ensures tight timing margins in high-speed control path logic. |
| Output Drive Strength | ±8.0 mA at VCC = 4.5 V - provides sufficient current to drive multiple CMOS loads or moderate PCB trace capacitance. |
| Operating Temperature | –40 °C to +125 °C - qualified for under-hood automotive modules, industrial PLC I/O, and extended-temperature embedded systems. |
| Power Dissipation | 250 mW maximum at Tamb ≤ 96 °C (TSSOP8) - supports continuous operation in thermally constrained PCB layouts. |
| Input Capacitance (CI) | 10 pF max - minimizes loading on upstream drivers and preserves signal integrity in fan-out-critical nodes. |
Pinout & Package
TSSOP8 plastic thin shrink small outline package (SOT505-2); 8 leads; body width 3 mm; lead length 0.5 mm; pin 1 index located below marking code in lower-left corner.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 1A | First OR gate input A - accepts overvoltage-tolerant logic signals up to 5.5 V. |
| 2 | 1B | First OR gate input B - electrically identical to 1A; enables dual-input OR function for primary logic path. |
| 3 | 2Y | Second OR gate output Y - drives downstream logic with symmetrical VOH/VOL and ±8 mA capability. |
| 4 | GND | Ground reference - common return path for all internal circuitry and output current sinks. |
| 5 | 2A | Second OR gate input A - independent of first gate; supports parallel logic evaluation. |
| 6 | 2B | Second OR gate input B - matches 1B functionality; enables compact dual-gate implementation. |
| 7 | 1Y | First OR gate output Y - provides dedicated output for first gate with identical drive specs as 2Y. |
| 8 | VCC | Positive supply - powers both gates; decoupling capacitor required within 10 mm for stable switching. |
Key Features
| Feature | Design Value |
|---|---|
| Overvoltage-tolerant inputs | Withstand 5.5 V regardless of VCC (2.0–5.5 V), enabling reliable level translation without external components. |
| Symmetrical output impedance | Matched pull-up/pull-down strength ensures consistent rise/fall times and reduces timing skew in critical paths. |
| High noise immunity | VIH = 3.85 V and VIL = 1.65 V at VCC = 5.5 V - provides >1.3 V noise margin against EMI in industrial environments. |
| Low dynamic power | CPD = 16 pF per buffer - limits switching power to <1 μW/MHz at 3.3 V, supporting battery-sensitive applications. |
| Latch-up immunity | Exceeds 100 mA per JESD78 Class II Level A - prevents destructive latch-up during transient overcurrent events. |
Applications
| Industrial Sensor Interface | Microcontroller GPIO Expansion |
|---|---|
|
Use Scenario: Aggregating fault signals from multiple temperature, pressure, and flow sensors into a single interrupt line for an MCU. IC Role / Device Role / Timing Role: Dual OR gate performing wired-OR logic summation with sub-4 ns propagation delay to preserve real-time response.

IC Role / Device Role / Timing Role: Combinatorial logic element generating composite status flags (e.g., "ERROR" = LED_ERR OR BUTTON_FAULT). Use Value: Reduces firmware complexity by offloading Boolean logic to hardware, freeing CPU cycles and simplifying ISR design. |
| Legacy Bus Signal Conditioning | Mixed-Voltage System Control Logic |
|
Use Scenario: Interfacing 5 V legacy RS-485 transceiver status outputs with a 3.3 V FPGA configuration manager. IC Role / Device Role / Timing Role: Level-translating OR gate accepting 5 V inputs while powered from 3.3 V supply, preserving signal polarity and timing. Use Value: Avoids dedicated level translators; maintains <10 ns total delay budget while ensuring VIH compliance at 3.3 V domain. |
Use Scenario: Generating system reset enable signals from multiple independent watchdog timeout indicators in a multi-rail power system. IC Role / Device Role / Timing Role: Fault-aggregation node combining WDT outputs across 1.8 V, 3.3 V, and 5 V subsystems into unified reset assertion. Use Value: Enables single-point reset coordination without voltage conflict or timing uncertainty due to input overvoltage tolerance. |
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 |
|---|---|---|---|
| 74AHCT2G32DP,125 | TTL-compatible input thresholds (VIH = 2.0 V min at VCC = 4.5–5.5 V) vs. CMOS thresholds in AHC version. | Better compatibility with legacy 5 V TTL outputs; less suitable for sub-3 V logic interfacing. | Select when interfacing with standard TTL sources; avoid if driving from low-voltage CMOS or battery-powered controllers. |
| SN74LVC2G32DCUR | Nominal 1.65–5.5 V supply range; slightly higher ICC (max 10 μA vs. 40 μA at 125 °C); same TSSOP8 footprint. | Lower static power at room temperature; tighter VOL spec (0.55 V max at 8 mA) improves noise margin in 3.3 V systems. | Prefer for ultra-low-quiescent-power designs or where tighter VOL is required; verify layout compatibility with thermal pad. |
Compared with 74AHC2G32DP,125, the AHCT variant offers superior TTL input compatibility but reduced low-voltage flexibility, while the LVC variant delivers lower static current and improved VOL at the cost of marginally higher dynamic power and different ESD ratings.

FAQ
Is the 74AHC2G32DP,125 pin-compatible with the 74AHCT2G32DP,125?
Yes - both share identical TSSOP8 (SOT505-2) pinout and mechanical footprint. However, input threshold behavior differs: the AHC version uses CMOS-compatible VIH/VIL (e.g., VIH = 3.85 V at VCC = 5.5 V), while the AHCT version uses TTL-compatible thresholds (VIH = 2.0 V min). Swapping requires verification of upstream driver compatibility.
What is the maximum capacitive load the 74AHC2G32DP,125 can drive reliably?
The device is characterized up to 50 pF load capacitance per output, with propagation delay specified at 15 pF and 50 pF. Driving >50 pF may increase tpd beyond datasheet limits and degrade edge rates; for heavier loads, add series termination or buffer stages. Output current remains within ±8 mA limits up to CL = 100 pF under recommended conditions.
Does the 74AHC2G32DP,125 require external pull-up or pull-down resistors on unused inputs?
No - unused inputs must be tied to VCC or GND to prevent floating states and excessive ICC. The device has no internal pull resistors. Leaving inputs unconnected risks increased power consumption, oscillation, and ESD susceptibility due to undefined input voltage.
Can the 74AHC2G32DP,125 operate at 1.8 V supply?
No - the absolute minimum supply voltage is 2.0 V per datasheet Section 9. Operation below 2.0 V is not characterized or guaranteed; VIH/VIL thresholds become undefined, and output drive collapses. For 1.8 V systems, consider the SN74LVC2G32 or 74LVC2G32 families instead.
