Product details
Overview
74HCT4075D-Q100 from Nexperia is an automotive-grade triple 3-input OR gate in SO14 (SOT108-1) package, operating from -40 °C to +125 °C with TTL-compatible inputs, 4.5–5.5 V supply range, and propagation delay of 12–36 ns at VCC = 4.5 V. It integrates input clamp diodes for overvoltage tolerance and meets AEC-Q100 Grade 1 qualification for engine control, body electronics, and ADAS signal conditioning.
For engineers reviewing the 74HCT4075D-Q100 datasheet, 74HCT4075D-Q100 pinout, 74HCT4075D-Q100 application, or 74HCT4075D-Q100 equivalent, this device supports robust logic-level translation in automotive powertrain and chassis modules where TTL input compatibility, thermal stability, and ESD resilience (HBM >2000 V) are critical selection criteria.
Technical Context
This device implements three independent OR logic functions (A+B+C → Y) using standard CMOS process with TTL-level input thresholds (VIH = 2.0 V min, VIL = 0.8 V max at VCC = 4.5–5.5 V), enabling direct interfacing with legacy 5 V microcontrollers and sensor outputs. Each gate features symmetrical input structure and rail-to-rail output swing.
Input clamp diodes allow safe operation with input voltages exceeding VCC when used with current-limiting resistors, supporting mixed-voltage subsystems. The SO14 package provides 14-pin leadframe layout optimized for automotive PCB reliability under thermal cycling and vibration stress.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar triple 3-input OR gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 74HC4075D-Q100 | CMOS-level inputs (VIH = 3.15 V min at VCC = 4.5 V); higher noise margin but incompatible with TTL sources | Suitable for pure CMOS systems (e.g., 3.3 V MCU with level-shifted 5 V sensors); not drop-in for TTL interfaces | Select when interfacing with 3.3 V logic families or when higher VIH improves noise immunity in high-EMI zones |
| SN74LVC1G3304DBVR | Single 3-input OR in SOT-23-6; 1.65–5.5 V supply; 3.7 ns typ tpd at 3.3 V; no AEC-Q100 qualification | Used in space-constrained non-automotive applications; lacks automotive qualification and triple-gate integration | Choose only for cost-sensitive consumer designs where AEC-Q100 is not required and board area is premium |

FAQ
Is 74HCT4075D-Q100 pin-compatible with non-automotive 74HCT4075 variants?
Yes, the 74HCT4075D-Q100 shares identical pinout, electrical characteristics, and SO14 (SOT108-1) package dimensions with industrial-grade 74HCT4075D. The Q100 suffix denotes AEC-Q100 qualification and extended temperature screening but does not alter physical or functional pin mapping.
What is the maximum recommended input voltage when using external current-limiting resistors?
Per datasheet Section 7, input voltage may exceed VCC by up to 0.5 V (i.e., VCC + 0.5 V) when input clamping current is limited to ±20 mA. For VCC = 5.5 V, absolute maximum input is 6.0 V; resistor value must ensure IIK ≤ 20 mA under worst-case overvoltage conditions.
Does this device support mixed-voltage operation between inputs and VCC?
No-inputs must remain within GND to VCC + 0.5 V. While clamp diodes permit transient excursions above VCC, sustained operation requires all driven inputs to reference the same VCC rail. It does not support true dual-supply or level-shifting functionality.
How does the 74HCT4075D-Q100 handle unused inputs?
Unused inputs must be tied to VCC or GND via ≤1 kΩ resistor to prevent floating states that cause increased ICC, noise susceptibility, and potential latch-up. Leaving inputs unconnected violates recommended operating conditions and risks erratic output behavior per Section 8 of the datasheet.
