Product details
Overview
74HCT4075DB,118 from Nexperia is a triple 3-input OR gate in SO14 (SOT108-1) package, designed for TTL-level input compatibility with 4.5 V to 5.5 V supply operation. It delivers propagation delay of 12 ns (typ) at VCC = 4.5 V, supports -40 °C to +125 °C ambient range, and features input clamp diodes enabling safe interfacing to voltages exceeding VCC - used in industrial control logic consolidation and digital signal routing.
For engineers reviewing the 74HCT4075DB,118 datasheet, 74HCT4075DB,118 pinout, 74HCT4075DB,118 application, or 74HCT4075DB,118 equivalent, key selection criteria include TTL-compatible input thresholds (VIH = 2.0 V min), guaranteed output drive (±4.0 mA), SO14 thermal derating (10.1 mW/K above 100 °C), and ESD robustness (HBM > 2000 V).
Technical Context
This device implements three independent 3-input OR gates in a single monolithic CMOS structure with TTL-compatible input circuitry. Each gate follows the Boolean function Y = A + B + C, with inputs tolerant of overvoltage via integrated clamp diodes and outputs capable of sourcing/sinking ±4.0 mA under recommended conditions.
It operates within a strict 4.5 V–5.5 V VCC window, exhibits VIH = 2.0 V (min) and VIL = 0.8 V (max) at 25 °C, and maintains functional timing across -40 °C to +125 °C without derating up to 100 °C - making it suitable for deterministic combinatorial logic in temperature-stable embedded systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 4.5 V to 5.5 V - ensures interoperability with standard 5 V TTL and mixed-voltage logic systems. |
| tpd (A→Y) | 12 ns (typ) at VCC = 4.5 V, CL = 50 pF - enables sub-25 ns worst-case gate-to-gate timing in synchronous logic paths. |
| IO Drive | ±4.0 mA - sufficient to directly drive multiple 74-series inputs or small LED indicators without buffering. |
| VIH / VIL | 2.0 V / 0.8 V (min/max) - guarantees reliable recognition of legacy TTL output levels across full temperature range. |
| Operating Temp | -40 °C to +125 °C - qualified for under-hood industrial and extended-temperature control applications. |
| ESD Rating | HBM > 2000 V, CDM > 1000 V - reduces risk of field failure during handling and PCB assembly. |
| Power Dissipation | 500 mW max at Tj ≤ 100 °C; linearly derated 10.1 mW/K above - defines thermal design margin for SO14 layout. |
Pinout & Package
Supplied in plastic small outline package (SO14), SOT108-1, 14-lead, body width 3.9 mm, with 1.27 mm lead pitch and gull-wing terminations compatible with standard reflow profiles.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1A, 2A, 3A | Input A of Gate 1/2/3 | First input per OR gate; accepts TTL-level signals with internal clamping diode protection. |
| 1B, 2B, 3B | Input B of Gate 1/2/3 | Second input per OR gate; electrically identical to 1A/2A/3A, fully interchangeable. |
| 1C, 2C, 3C | Input C of Gate 1/2/3 | Third input per OR gate; shares same VIH/VIL specs and current-limiting resistor compatibility. |
| 1Y, 2Y, 3Y | Output Y of Gate 1/2/3 | OR result (Y = A+B+C); drives loads up to ±4.0 mA while maintaining VOH ≥ 3.98 V and VOL ≤ 0.26 V. |
| GND | Ground Reference | 0 V return path for all logic and power currents; must be low-impedance for noise immunity. |
| VCC | Supply Voltage | +4.5 V to +5.5 V DC supply; decoupling capacitor (100 nF) required within 10 mm of pin 14. |
Key Features
| Feature | Design Value |
|---|---|
| TTL-compatible inputs | VIH = 2.0 V min, VIL = 0.8 V max at VCC = 4.5–5.5 V - eliminates level-shifting in legacy 5 V systems. |
| Input clamp diodes | Enables use of external current-limiting resistors for interfacing to voltages > VCC - simplifies mixed-rail signal conditioning. |
| High noise immunity | Input hysteresis not present, but guaranteed VIH/VIL margins provide >1.2 V noise margin at nominal VCC. |
| Low static power | ICC ≤ 40 μA max at +125 °C - supports always-on logic monitoring without thermal penalty. |
| Robust ESD protection | HBM > 2000 V, CDM > 1000 V - exceeds JEDEC JS-001 Class 2 and JS-002 Class C3 requirements. |
Applications
| Industrial PLC I/O Expansion | Automated Test Equipment (ATE) Signal Routing |

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 |
|---|---|---|---|
| SN74HCT4075DR | Same logic function, SO14 package, identical VIH/VIL and tpd specs; TI part uses different die revision and minor ICC variation (≤5 μA higher at 25 °C). | Qualified to AEC-Q100 Grade 3; suitable for automotive-adjacent industrial environments where extended qualification is mandated. | Select when automotive-grade documentation or PPAP support is contractually required. |
| 74HCT4075PW,118 | TSSOP14 (SOT402-1) package; identical electrical specs but 30 % smaller footprint and 15 % lower thermal resistance (θJA = 125 K/W vs 160 K/W). | Better suited for high-density PCBs with tight thermal constraints; requires finer-pitch reflow profile and optical inspection. | Select when board area is constrained and automated optical inspection capability exists. |
Compared with SN74HCT4075DR and 74HCT4075PW,118, the 74HCT4075DB,118 offers optimal balance of industrial temperature coverage, proven SO14 manufacturability, and direct drop-in compatibility with legacy 74-series layouts - making it preferred for cost-sensitive, volume production of non-automotive control hardware.

FAQ
Can 74HCT4075DB,118 operate at 3.3 V supply?
No. The 74HCT4075DB,118 is specified only for 4.5 V to 5.5 V operation per its Recommended Operating Conditions table. At 3.3 V, VIH and VOH parameters fall outside guaranteed limits, risking unreliable logic interpretation and marginal output drive. Use 74HC4075 or 74LVC4075 for 3.3 V systems.
What is the maximum capacitive load this device can drive reliably?
The datasheet specifies dynamic characteristics up to CL = 50 pF. While the output can physically drive larger loads, propagation delay increases linearly with capacitance (e.g., tpd ≈ 24 ns at CL = 100 pF, VCC = 4.5 V). For CL > 50 pF, add a buffer stage or verify timing closure with actual board parasitics.
Does this part include Schmitt-trigger inputs?
No. The 74HCT4075DB,118 has standard CMOS input structure with no hysteresis. Its input thresholds (VIH = 2.0 V, VIL = 0.8 V) are fixed relative to VCC and do not provide noise rejection for slow-rising signals. For noisy environments, external RC filtering or a dedicated Schmitt-trigger gate (e.g., 74HCT14) is required upstream.
Is GND pin (pin 7) the only ground connection needed?
Yes. Pin 7 is the sole ground terminal for both logic reference and power return. No separate analog/digital ground pins exist. To ensure noise immunity, connect pin 7 to a low-impedance, solid ground plane with minimal trace length and place a 100 nF ceramic decoupling capacitor between pins 14 (VCC) and 7 (GND) as close to the package as possible.
