Product details
Overview
74HCT4075PW,118 from Nexperia is a triple 3-input OR gate logic IC with TTL-compatible input thresholds (VIH = 2.0 V min, VIL = 0.8 V max at VCC = 5 V), 14-pin SO14 (SOT108-1) package, propagation delay of 12 ns typical at VCC = 4.5 V/CL = 50 pF, and operation across -40 °C to +125 °C - used in industrial control signal combiners and digital bus arbitration circuits.
For engineers reviewing the 74HCT4075PW,118 datasheet, 74HCT4075PW,118 pinout, 74HCT4075PW,118 application, or 74HCT4075PW,118 equivalent, key selection criteria include input voltage compatibility with legacy TTL systems, guaranteed output drive strength (±4 mA at VCC = 4.5 V), thermal robustness over extended temperature range, and SO14 footprint compatibility with automated PCB assembly.
Technical Context
This device implements three independent 3-input OR gates in a single monolithic CMOS structure with integrated input clamp diodes, enabling safe interfacing to voltages exceeding VCC when current-limiting resistors are used. Each gate follows strict Boolean OR logic: output is HIGH if ≥1 input is HIGH.
It operates under JEDEC-standard TTL input levels (not CMOS), ensuring direct compatibility with 5 V TTL families without level-shifting. The SO14 package supports surface-mount reflow profiles and provides 14 terminals with dedicated VCC (pin 14), GND (pin 7), and symmetrical I/O layout for noise-resilient routing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Function | Triple independent 3-input OR gate; each outputs HIGH if ≥1 input is HIGH (no internal inter-gate coupling) |
| Input Voltage Compatibility | TTL-level: VIH ≥ 2.0 V, VIL ≤ 0.8 V at VCC = 4.5–5.5 V - directly interfaces 5 V TTL, LSTTL, and microcontroller GPIOs |
| Propagation Delay | 12 ns typical (nA/nB/nC → nY) at VCC = 4.5 V, CL = 50 pF - enables reliable timing in ≤33 MHz combinatorial paths |
| Output Drive Strength | ±4.0 mA at VOH ≥ 3.98 V / VOL ≤ 0.26 V (VCC = 4.5 V) - sufficient to drive 10 LSTTL loads or fan out to multiple CMOS inputs |
| Operating Temperature | -40 °C to +125 °C - qualified for under-hood automotive modules, industrial PLC backplanes, and high-ambient power supplies |
| ESD Robustness | HBM > 2000 V, CDM > 1000 V - withstands handling and board-level ESD events without latch-up or parameter shift |
| Supply Voltage Range | 4.5 V to 5.5 V - tightly regulated for stable logic thresholds in 5 V systems; not rated for 3.3 V operation |
Pinout & Package
Supplied in plastic small outline package (SO14), SOT108-1: 14-lead, 3.9 mm body width, 1.27 mm lead pitch, gull-wing leads compatible with IPC-7351B SOIC-14 footprint.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1A, 2A, 3A (pins 3, 1, 11) | Input A of Gate 1/2/3 | First input per OR gate; accepts TTL-level signals; clamped to VCC/GND via on-chip diodes |
| 1B, 2B, 3B (pins 4, 2, 12) | Input B of Gate 1/2/3 | Second input per OR gate; electrically identical to 1A/2A/3A; no crosstalk between gates |
| 1C, 2C, 3C (pins 5, 8, 13) | Input C of Gate 1/2/3 | Third input per OR gate; shares same VIH/VIL specs and ESD protection as other inputs |
| 1Y, 2Y, 3Y (pins 6, 9, 10) | Output Y of Gate 1/2/3 | CMOS push-pull output; drives HIGH to ≥3.98 V / LOW to ≤0.26 V under 4 mA load |
| GND (pin 7) | Ground Reference | Primary 0 V return path for all logic and supply currents; must be low-impedance for noise immunity |
| VCC (pin 14) | Positive Supply | 5 V nominal supply; decoupling capacitor (100 nF) required within 5 mm for stable switching |
Key Features
| Feature | Design Value |
|---|---|
| TTL-compatible inputs | Enables direct connection to legacy 5 V TTL logic without level shifters or pull-ups |
| Input clamp diodes | Allows safe interface to signals up to VCC + 0.5 V using external current-limiting resistors |
| Wide temperature range | Guaranteed functionality from -40 °C to +125 °C supports industrial and automotive under-hood use |
| Low quiescent current | ICC ≤ 2.0 μA typical at VCC = 5.5 V ensures minimal standby power in battery-backed systems |
| High noise immunity | Input hysteresis not present, but VIH/VIL margins (1.2 V at 5 V) provide 40% noise margin against ground bounce |
Applications
| Industrial Control Signal Merging | Digital Bus Arbitration Logic |
|---|---|
Use Scenario: Combining fault signals from three independent motor drivers into a single system-fault line. IC Role / Device Role / Timing Role: OR gate aggregating active-HIGH fault flags; no propagation delay sensitivity due to asynchronous nature. Use Value: Reduces wiring complexity by replacing discrete diode-OR networks; eliminates voltage drop and leakage issues inherent in passive ORing. |
Use Scenario: Resolving bus master priority in a multi-controller CAN/LIN subsystem where any controller may request bus access. IC Role / Device Role / Timing Role: Combinatorial arbitration node generating BUS_REQUEST_ACTIVE signal when ≥1 controller asserts request. Use Value: Ensures deterministic response <15 ns after first request edge - faster than software polling and immune to CPU lockup. |
| Power Sequencing Monitor | Legacy System Glue Logic |
Use Scenario: Monitoring three independent DC/DC converter OK signals to enable downstream FPGA configuration only when all rails are stable. IC Role / Device Role / Timing Role: Final-stage "AND" function implemented via De Morgan's theorem (inverted inputs + OR gate + inverter), though here used directly as OR for fail-safe activation. Use Value: Provides hardware-enforced power-good interlock with zero firmware dependency and sub-20 ns decision latency. |
Use Scenario: Adapting 74LS-series peripheral address decoding logic to interface with modern microcontrollers lacking native LS drive capability. IC Role / Device Role / Timing Role: Level-translating AND/OR combinatorial block preserving original TTL timing behavior in retro-computing or test equipment upgrades. Use Value: Maintains functional equivalence while eliminating obsolete 74LS parts; SO14 package fits existing PCB footprints. |
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, TTL inputs, SO14 package; propagation delay 13 ns (typ) at VCC = 4.5 V - 1 ns slower than 74HCT4075PW,118 | TI part uses different internal layout; slightly higher ICC (3.5 μA max vs. 2.0 μA) affects ultra-low-power sleep modes | Select when TI supply chain alignment or dual-sourcing is required; verify layout clearance for thermal pad absence |
| MC74HCT4075ADTR2G | ON Semiconductor variant; identical pinout and DC specs; dynamic specs match within 0.5 ns; qualified to AEC-Q100 Grade 2 (-40 °C to +105 °C) | Limited to +105 °C ambient (vs. +125 °C for Nexperia); not suitable for under-hood engine control modules | Choose for automotive infotainment or body-control units where Grade 2 suffices and ON Semi sourcing is preferred |
Compared with SN74HCT4075DR and MC74HCT4075ADTR2G, the 74HCT4075PW,118 offers the fastest propagation delay (12 ns typ), lowest ICC (2.0 μA), and widest operating temperature range (+125 °C), making it optimal for high-reliability industrial timing-critical combinatorial logic.

FAQ
Is 74HCT4075PW,118 compatible with 3.3 V logic systems?
No. The 74HCT4075PW,118 is specified only for VCC = 4.5 V to 5.5 V and requires TTL-level inputs (VIH ≥ 2.0 V). Driving it from 3.3 V GPIOs violates VIH minimum and risks unreliable HIGH recognition. Use 74LVC4075 or level translators for mixed-voltage designs.
Can unused inputs be left floating?
No. Floating inputs cause increased ICC, noise susceptibility, and potential oscillation. All unused inputs must be tied to VCC or GND via ≤1 kΩ resistor. For OR gates, tie unused inputs LOW (GND) to avoid forcing output HIGH unintentionally.
What is the maximum capacitive load this device can drive reliably?
The datasheet specifies dynamic characteristics up to CL = 50 pF. While it can drive heavier loads, propagation delay increases linearly (~0.2 ns/pF above 50 pF), and output rise/fall times degrade. For >50 pF, add a buffer stage or reduce trace length and stubs.
Does this part support hot insertion or live swapping?
No. The 74HCT4075PW,118 lacks hot-swap protection circuitry such as power-up reset, Ioff, or partial-power-down features. Applying VCC or signals before GND stabilization may cause latch-up or parametric shift. Always sequence power and signals per JEDEC guidelines.
