Product details
Overview
74AHCT2G32DC-Q100 from Nexperia is an automotive-grade dual 2-input OR gate in VSSOP8 (SOT765-1) package, operating from 4.5 V to 5.5 V supply, with TTL-compatible inputs, ±8 mA output drive, and propagation delay as low as 3.3 ns (typ.) at 5 V/15 pF. It serves as a level-translating logic buffer in body control modules and powertrain interface circuits.
For engineers reviewing the 74AHCT2G32DC-Q100 datasheet, 74AHCT2G32DC-Q100 pinout, 74AHCT2G32DC-Q100 application, or 74AHCT2G32DC-Q100 equivalent, this device is selected for AEC-Q100 Grade 1 automotive systems requiring robust noise immunity, overvoltage-tolerant inputs up to 5.5 V, and guaranteed operation from −40 °C to +125 °C.
Technical Context
This device implements two independent OR logic functions with symmetrical output impedance and balanced propagation delays between rising and falling edges. Its TTL-level input thresholds (VIH = 2.0 V min, VIL = 0.8 V max at VCC = 4.5–5.5 V) ensure compatibility with legacy 5 V microcontrollers and sensor interfaces.
Designed for mixed-voltage translation, it accepts inputs up to 5.5 V regardless of VCC, enabling safe interfacing between 3.3 V controllers and 5 V peripherals. The device meets AEC-Q100 Grade 1 qualification with latch-up immunity >100 mA and HBM ESD >2000 V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Function | Dual 2-input OR gate - provides two independent Boolean OR operations per package |
| Supply Voltage Range | 4.5 V to 5.5 V - supports stable operation across automotive battery voltage transients |
| Propagation Delay | 3.3 ns (typ.) at VCC = 5.0 V, CL = 15 pF - enables timing-critical signal routing in ADAS sensor fusion paths |
| Output Drive | ±8 mA at VOH/VOL - sufficient to directly drive multiple 74-series inputs or small LED indicators |
| Input Thresholds | VIH ≥ 2.0 V, VIL ≤ 0.8 V - ensures reliable recognition of TTL logic levels from legacy ECUs |

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 overvoltage-tolerant signals up to 5.5 V |
| 2 | 1B | First OR gate input B - electrically identical to 1A; enables dual-input logic decision |
| 3 | 2Y | Second OR gate output - drives downstream logic or status indicators with CMOS-compatible swing |
| 4 | GND | Ground reference - must be low-impedance connection to minimize switching noise coupling |
| 5 | 2A | Second OR gate input A - isolated from first gate; supports independent logic path routing |
| 6 | 2B | Second OR gate input B - paired with 2A to form second OR function; no internal crosstalk |
| 7 | 1Y | First OR gate output - provides active-HIGH result of 1A OR 1B; fan-out limited by ±8 mA spec |
| 8 | VCC | Positive supply - decoupling capacitor (100 nF) required within 5 mm for stable high-speed operation |
Key Features
| Feature | Design Value |

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-Q100 | TSSOP8 (SOT505-2) package; 3 mm body width vs. 2.3 mm; 0.5 mm lead length vs. shorter VSSOP leads | Better thermal dissipation (Ptot derating starts at 96 °C vs. 99 °C), suited for higher-power-density layouts | Select when board space allows larger footprint and thermal margin is prioritized over miniaturization |
| SN74LVC2G32QDCURQ1 | TI part; 1.65–5.5 V supply range; CMOS inputs (not TTL); 32 mA output drive; different pinout (1A/1B/1Y/GND/VCC/2A/2B/2Y) | Wider voltage flexibility but lacks native TTL compatibility; requires redesign if interfacing with 5 V TTL sources | Choose only if system uses mixed 1.8/3.3/5 V rails and TTL-level inputs are absent |
Compared with 74AHCT2G32DP-Q100, the DC variant offers smaller PCB footprint and slightly higher thermal resistance, while SN74LVC2G32QDCURQ1 trades TTL compatibility for broader supply range and higher drive - making the 74AHCT2G32DC-Q100 optimal for cost-sensitive, space-constrained automotive modules requiring legacy 5 V signal interoperability.

FAQ
Is 74AHCT2G32DC-Q100 pin-compatible with 74AHC2G32DC-Q100?
Yes - both share identical VSSOP8 (SOT765-1) pinout and terminal functions. However, 74AHCT2G32DC-Q100 uses TTL input thresholds (VIH ≥ 2.0 V), while 74AHC2G32DC-Q100 uses CMOS thresholds (VIH ≥ 3.85 V at 5.5 V). Swapping requires verifying source logic levels match the target input specification.
What is the maximum capacitive load this device can drive reliably?
The datasheet specifies timing performance up to 50 pF load capacitance, with tpd = 4.8–10.0 ns depending on VCC and temperature. For loads exceeding 50 pF, propagation delay increases linearly and output rise/fall times degrade; external buffering is recommended above 75 pF to maintain signal integrity.
Can this OR gate be used as a wired-OR bus combiner?
No - it is not designed for open-drain or wired-OR bus topologies. Both outputs are push-pull CMOS and will conflict if externally shorted. Use dedicated bus switches or discrete diodes for true wired-OR implementation; this device functions only as a standard logic gate with defined input/output isolation.
Does the overvoltage tolerance apply during power-down conditions?
Yes - inputs remain tolerant to 5.5 V even when VCC = 0 V, enabling hot-plug or partial-power-down scenarios. This is validated per datasheet limiting values (VI = −0.5 V to +7.0 V), allowing safe signal presence on inputs prior to VCC ramp-up or after VCC removal.
