Product details
Overview
74AHCT2G32DP-Q100 from Nexperia is a dual 2-input OR gate IC qualified to AEC-Q100 Grade 1, operating from -40 °C to +125 °C with TTL-compatible inputs, 2.0–5.5 V supply range, overvoltage-tolerant inputs up to 5.5 V, and propagation delay as low as 3.3 ns (typ.) at VCC = 5.0 V/CL = 15 pF-used in automotive body control modules for discrete signal combining and level translation.
For engineers reviewing the 74AHCT2G32DP-Q100 datasheet, 74AHCT2G32DP-Q100 pinout, 74AHCT2G32DP-Q100 application, or 74AHCT2G32DP-Q100 equivalent, this page delivers verified functional identity, automotive-grade thermal and voltage specs, TSSOP8 package mapping, real-world logic-level translation use cases, and validated alternatives with input threshold and timing differences.
Technical Context
This device implements two independent OR logic functions in a single monolithic CMOS structure, with TTL-level input thresholds (VIH ≥ 2.0 V, VIL ≤ 0.8 V at VCC = 4.5–5.5 V) and rail-to-rail CMOS output drive capability. Its overvoltage-tolerant inputs enable safe interfacing between 3.3 V and 5 V domains without external level shifters.
Designed for automotive environments, it meets AEC-Q100 Grade 1 requirements with latch-up immunity >100 mA (JESD78 Class II Level A), HBM ESD >2000 V, and CDM ESD >1000 V. Propagation delays are balanced (tPLH ≈ tPHL), and output impedance is symmetrical for consistent rise/fall times under load.
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 standard 5 V automotive systems with ±10% tolerance. |
| Input Threshold Type | TTL-compatible - VIH ≥ 2.0 V, VIL ≤ 0.8 V enables direct connection to legacy 5 V microcontrollers and sensors. |
| Propagation Delay | 3.3 ns (typ.) at VCC = 5.0 V, CL = 15 pF - ensures fast signal routing in time-critical control paths. |
| Operating Temperature | -40 °C to +125 °C - qualified for under-hood and powertrain applications per AEC-Q100 Grade 1. |
| Input Overvoltage Tolerance | Up to 5.5 V - allows safe operation when inputs exceed VCC, enabling mixed-voltage domain interfacing. |
| Output Drive Strength | ±8.0 mA at VCC = 4.5 V - sufficient to drive multiple CMOS/TTL loads or small capacitive traces. |
Pinout & Package
TSSOP8 plastic thin shrink small outline package (SOT505-2); 8 leads; body width 3 mm; lead length 0.5 mm; pin 1 indicator located on lower left corner below marking code 'C32'.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 1A | First OR gate input A - accepts TTL-level signals; overvoltage tolerant to 5.5 V. |
| 2 | 1B | First OR gate input B - identical electrical characteristics to Pin 1; enables dual-input logic sum. |
| 3 | 2Y | Second OR gate output - drives downstream logic or interface circuitry with CMOS-compatible swing. |
| 4 | GND | Ground reference (0 V) - must be low-impedance connection for noise immunity and stable logic levels. |
| 5 | 2A | Second OR gate input A - electrically isolated from first gate; supports independent signal routing. |
| 6 | 2B | Second OR gate input B - paired with Pin 5 to form second OR function; same input specs as Pins 1/2. |
| 7 | 1Y | First OR gate output - provides logic-high when either 1A or 1B is high; rail-to-rail CMOS output. |
| 8 | VCC | Positive supply rail - powers both gates; decoupling capacitor required near this pin for stability. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 Grade 1 qualification | Validated for automotive use across -40 °C to +125 °C ambient, including lifetime reliability testing. |
| Overvoltage-tolerant inputs | Accepts up to 5.5 V regardless of VCC setting - eliminates need for external clamping diodes in mixed-voltage designs. |
| TTL-compatible input thresholds | VIH ≥ 2.0 V and VIL ≤ 0.8 V at 5 V supply - ensures interoperability with legacy 5 V controllers and sensors. |
| Symmetrical output impedance | Matched pull-up/pull-down strength - yields balanced rise/fall times (<10% skew) under capacitive loading. |
| Low dynamic power dissipation | CPD = 17 pF per buffer - enables efficient operation in battery-sensitive modules with minimal self-heating. |
Applications
| Body Control Module Signal Aggregation | Door Lock Status Monitoring |
|---|---|
Use Scenario: Combining door ajar, window position, and mirror fold signals into a single status flag for CAN gateway reporting. IC Role / Device Role / Timing Role: Dual OR gate performs real-time logical OR of three independent sensor inputs per channel, reducing MCU GPIO count. Use Value: Enables deterministic response within 7.0 ns (max) at 125 °C, meeting ASIL-B timing constraints for non-safety-critical aggregation. |
Use Scenario: Detecting any active lock/unlock request from driver, passenger, or key fob receiver outputs. IC Role / Device Role / Timing Role: Acts as wired-OR combiner for multiple asynchronous lock command sources before feeding to central actuator driver. Use Value: Overvoltage tolerance allows direct connection to 5 V fob receiver outputs while powered from 5 V body domain rail - no level shifter needed. |
| Engine Bay Sensor Fault Detection | Headlamp Switch Logic Interface |
Use Scenario: Monitoring open-circuit faults across multiple temperature or pressure sensors by OR-ing their diagnostic flags. IC Role / Device Role / Timing Role: Provides fail-fast indication: output goes high if any connected sensor reports fault condition. Use Value: Guaranteed operation at +125 °C ambient ensures reliability in high-temperature engine bay locations without derating. |
Use Scenario: Interfacing mechanical headlamp switch (5 V TTL output) with 3.3 V microcontroller input via OR logic for manual override path. IC Role / Device Role / Timing Role: Performs level translation and logic combination between switch states and automatic lighting controller outputs. Use Value: Input overvoltage tolerance permits direct 5 V switch connection while VCC = 5 V - avoids external resistor-divider networks. |
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 |
|---|---|---|---|
| 74AHCT2G32DC-Q100 | VSSOP8 package (2.3 mm width); identical electrical specs and AEC-Q100 qualification. | Requires higher PCB assembly precision due to finer pitch (0.5 mm vs TSSOP8's 0.65 mm); better for space-constrained modules. | Select when board area is constrained and automated placement capability supports 0.5 mm pitch. |
| SN74AHCT2G32QDCURQ1 | Texas Instruments part; same function, AEC-Q100 Grade 1, but uses different ESD spec (HBM >4000 V) and slightly higher ICC (max 40 μA vs 10 μA at 125 °C). | Higher ESD robustness may benefit high-noise under-hood zones; higher leakage could impact ultra-low-power sleep modes. | Prefer where field ESD exposure exceeds 2 kV or where TI's long-term supply assurance is prioritized. |
Compared with 74AHCT2G32DP-Q100, the DC variant offers smaller footprint at cost of assembly complexity, while the TI alternative trades marginally higher static current for enhanced ESD resilience-both require validation of timing and thermal behavior in final layout.

FAQ
Is 74AHCT2G32DP-Q100 pin-compatible with 74AHC2G32DP-Q100?
Yes-both share identical TSSOP8 pinout and logic function, but differ in input threshold: 74AHCT2G32DP-Q100 uses TTL-compatible inputs (VIH ≥ 2.0 V), while 74AHC2G32DP-Q100 requires CMOS-level inputs (VIH ≥ 3.85 V at VCC = 5.5 V). Swapping requires verifying source driver compatibility.
What is the maximum capacitive load this device can drive reliably?
Per datasheet Table 8, it is characterized up to 50 pF load capacitance with guaranteed timing (tpd ≤ 10.0 ns max at 125 °C). Driving >50 pF may increase propagation delay and reduce noise margin; for >100 pF, consider buffering or layout optimization.
Does this device support partial power-down or I/O isolation when VCC = 0 V?
No-inputs are overvoltage tolerant but not bus-hold or I/O-isolated. When VCC = 0 V, inputs remain functional up to 5.5 V, but outputs enter high-impedance only if explicitly disabled (not applicable here); unpowered operation risks back-powering VCC through input clamps.
Can 74AHCT2G32DP-Q100 operate at 3.3 V supply?
No-it is specified only for 4.5 V to 5.5 V supply per Table 6. At 3.3 V, VIH threshold (≥2.0 V) would still be met, but VOH/VOL performance degrades outside recommended conditions, and AEC-Q100 qualification does not cover 3.3 V operation.
