Product details
Overview
74AHCT1G32GW-Q100 from Nexperia is an automotive-qualified single 2-input OR gate in TSSOP5 (SOT353-1) package, operating from 4.5 V to 5.5 V supply, with TTL-compatible inputs, 8 mA output drive, and propagation delay of 3.3 ns (typ) at 5 V/15 pF. It functions as a level-translating logic buffer in powertrain control modules and body electronics where mixed-voltage signal conditioning is required.
For engineers reviewing the 74AHCT1G32GW-Q100 datasheet, 74AHCT1G32GW-Q100 pinout, 74AHCT1G32GW-Q100 application, or 74AHCT1G32GW-Q100 equivalent, this device serves as a high-noise-immunity, AEC-Q100 Grade 1-compliant logic gate for automotive signal routing, fault detection logic, and sensor interface combinatorial logic - requiring verified input voltage thresholds, output drive capability, thermal derating behavior, and package-level solderability validation.
Technical Context
This device implements standard positive-logic OR functionality (Y = A + B) with symmetrical output impedance and balanced propagation delays between both inputs and output. 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 microcontroller GPIOs and sensor outputs.
Designed for automotive ambient ranges (−40 °C to +125 °C), it features overvoltage-tolerant inputs up to 5.5 V independent of VCC, enabling safe interfacing across voltage domains without external clamping. Static and dynamic characteristics are fully specified across temperature and voltage extremes per AEC-Q100 stress testing protocols.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Function | Single 2-input OR gate (Y = A OR B); enables basic combinatorial decision logic in safety-critical signal paths. |

Pinout & Package
TSSOP5 (SOT353-1) plastic thin shrink small outline package: 5-lead, 1.25 mm body width, 0.65 mm pitch, side-wettable flanks not applicable. Designed for automated optical inspection and reflow-solderable mounting on compact automotive PCBs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

| Overvoltage-tolerant inputs | Withstand 5.5 V input signals even when VCC = 4.5 V, eliminating need for external level-shifting components. |
| High noise immunity | Guaranteed 0.4 V noise margin at VCC = 5.0 V due to tightly controlled VIH/VIL spacing and hysteresis-free design. |
| Symmetrical output impedance | Matched pull-up/pull-down strength ensures consistent rise/fall times and reduces signal distortion on shared buses. |
| Low static power consumption | ICC ≤ 40 μA max at VCC = 5.5 V and full temperature range, minimizing quiescent current in always-on modules. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 2-input OR gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 74AHCT1G32GV-Q100 | Same logic function and AEC-Q100 Grade 1 rating, but in SC-74A (SOT753) package with 0.95 mm lead pitch and higher thermal resistance. | Preferred for wave-soldered legacy designs or where larger pad geometry improves mechanical reliability in high-vibration environments. | Select when board assembly uses through-hole compatible reflow profiles or requires greater creepage distance than TSSOP5 allows. |
| SN74LVC1G32QDRYRQ1 | TI part with LVC-family 1.65–5.5 V supply range, lower VIH (1.7 V min), and 32 mA drive - but only AEC-Q100 Grade 2 (−40 °C to +105 °C). | Acceptable for cabin electronics with less extreme thermal requirements, but not certified for under-hood use. | Choose only for non-engine-compartment applications where wider VCC range and higher drive outweigh Grade 1 qualification needs. |
Compared with 74AHCT1G32GV-Q100, the GW variant offers finer pitch and better thermal dissipation in space-constrained layouts; versus SN74LVC1G32QDRYRQ1, it trades wider supply flexibility for guaranteed Grade 1 operation and tighter input threshold control essential for robust automotive signal integrity.

FAQ
What is the maximum allowable input voltage relative to VCC?
The 74AHCT1G32GW-Q100 supports overvoltage-tolerant inputs up to 5.5 V regardless of VCC level - meaning inputs may exceed VCC by up to 1.0 V when VCC = 4.5 V. This eliminates risk of damage during hot-plug or voltage-ramp mismatch scenarios common in automotive subsystem integration.
Does this device support 3.3 V logic interfacing?
No - the 74AHCT1G32GW-Q100 is TTL-input compatible and specified only for VCC = 4.5 V to 5.5 V. Its VIH minimum is 2.0 V, making it unsuitable for direct connection to 3.3 V CMOS outputs without level translation, unlike the 74AHC1G32GW-Q100 variant which supports 2.0–5.5 V supplies and CMOS inputs.
How does thermal derating affect power dissipation in the TSSOP5 package?
In the SOT353-1 (TSSOP5) package, total power dissipation derates linearly at 3.3 mW/K above +74 °C. At +125 °C ambient, usable Ptot drops to approximately 85 mW from the 250 mW rated value - requiring careful thermal design in sealed enclosures or high-power-density layouts.
Can this OR gate be used in fail-safe monitoring circuits?
Yes - its AEC-Q100 Grade 1 qualification, latch-up immunity (>100 mA), and guaranteed propagation delay (≤9.0 ns at 5 V/15 pF) make it suitable for hardware-based safety monitors. When paired with redundant sensors and configured in OR logic, it delivers deterministic fault assertion independent of software execution state.
