Product details
Overview
74HC05D,118 from Nexperia is a hex inverter IC with six independent open-drain CMOS outputs, designed for wired-OR/AND logic implementation in level-shifting and bus interface circuits. It operates from 2.0 V to 6.0 V, supports -40 °C to +125 °C ambient range, delivers 27 ns max propagation delay at 4.5 V, and requires external pull-up resistors for output functionality - used in I²C bus buffering and mixed-voltage signal translation.
For engineers reviewing the 74HC05D,118 datasheet, 74HC05D,118 pinout, 74HC05D,118 application, or 74HC05D,118 equivalent, key selection criteria include open-drain drive capability, wide supply voltage tolerance, industrial temperature rating, and SO14 package compatibility with legacy 74-series footprint layouts.
Technical Context
The 74HC05D implements six identical inverting buffers with true open-drain outputs - no internal pull-ups - enabling direct connection to shared busses without contention. Each gate exhibits rail-to-rail input thresholds (VIH = 3.15 V min at VCC = 4.5 V; VIL = 1.35 V max), ensuring robust noise immunity across its operating voltage range.
Its functional behavior follows a strict L→Z / H→L output mapping: low input yields high-impedance (OFF) state; high input forces output low. This enables active-LOW wired-OR logic when multiple outputs share a common pull-up, and supports bidirectional data lines in protocols like I²C where external pull-ups define bus idle state.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Function | Hex inverter with open-drain outputs - enables wired-OR logic and voltage-level translation |
| Supply Voltage Range | 2.0 V to 6.0 V - compatible with 3.3 V and 5 V systems, supports mixed-voltage interfacing |
| Propagation Delay | 27 ns max at VCC = 4.5 V, Tamb = +125 °C - ensures timing compliance in high-speed digital control paths |
| Output Drive | 5.2 mA sink at VO ≤ 0.4 V (VCC = 6.0 V) - sufficient to drive standard 1 kΩ pull-ups on I²C or SMBus lines |
| Operating Temperature | -40 °C to +125 °C - qualified for industrial and under-hood automotive auxiliary circuits |
| Input Thresholds | VIH = 3.15 V min, VIL = 1.35 V max at VCC = 4.5 V - provides >1.8 V noise margin in 5 V systems |
| ESD Protection | HBM > 2000 V, CDM > 1000 V - meets JEDEC JS-001/JS-002 for robust handling in automated assembly |
Pinout & Package
74HC05D,118 is housed in a 14-lead SO14 (SOT108-1) plastic small outline package, 3.9 mm body width, with gull-wing leads and pin 1 index marker. The package is RoHS-compliant and rated for reflow soldering per J-STD-020.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 3, 5, 9, 11, 13 | Input (1A–6A) | CMOS-compatible logic inputs - accept 0 V to VCC; no current injection required |
| 2, 4, 6, 8, 10, 12 | Output (1Y–6Y) | Open-drain NMOS outputs - must be externally pulled up; sink current only |
| 7 | GND | Ground reference (0 V) - all voltage levels referenced here; mandatory connection |
| 14 | VCC | Positive supply rail - powers internal logic; decoupling capacitor recommended near pin |
Key Features
| Feature | Design Value |
|---|---|
| Wide supply range | 2.0 V to 6.0 V operation - eliminates need for level shifters between 3.3 V controllers and 5 V peripherals |
| Open-drain architecture | Six independent open-drain outputs - enables shared-bus arbitration and multi-master I²C node design |
| High ESD robustness | HBM > 2000 V, CDM > 1000 V - reduces risk of field failure during handling and PCB assembly |
| Industrial temperature grade | -40 °C to +125 °C operation - supports deployment in motor drives, PLC I/O modules, and power supply supervisors |
| Low static current | ICC ≤ 40 μA max at VCC = 6.0 V - minimizes quiescent power in always-on monitoring circuits |
Applications
| I²C Bus Level Translation | LED Matrix Row Driver |
|---|---|
|
Use Scenario: Interfacing a 3.3 V microcontroller I²C port to 5 V sensors or EEPROMs. IC Role / Device Role / Timing Role: Open-drain inverter acting as bi-directional level translator for SDA/SCL lines. Use Value: Eliminates discrete MOSFET translators; leverages existing 5 V pull-ups while preserving I²C timing integrity up to 400 kHz. |
Use Scenario: Driving common-anode LED matrix rows with active-low enable logic. IC Role / Device Role / Timing Role: Inverting buffer sinking current from row cathodes via external current-limiting resistors. Use Value: Provides clean logic inversion and 5.2 mA sink capability per output - sufficient for 20 mA LED rows with 240 Ω series resistance. |
| Wired-OR Interrupt Aggregation | Reset Signal Conditioning |
|
Use Scenario: Combining interrupt signals from multiple peripherals onto a single MCU IRQ line. IC Role / Device Role / Timing Role: Six inverters configured as active-LOW wired-OR - any low input pulls shared output low. Use Value: Enables hardware OR-ing without additional diodes or logic gates; preserves fast edge response (<27 ns). |
Use Scenario: Generating a synchronized, debounced system reset from multiple asynchronous sources. IC Role / Device Role / Timing Role: Inverter stage conditioning pushbutton or watchdog reset signals before feeding MCU reset pin. Use Value: Adds noise immunity via CMOS thresholds and allows external RC filtering on input while maintaining deterministic active-low reset polarity. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar hex inverter with open-drain applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74HC05DR | SO14 package, same logic function and open-drain outputs; TI version with slightly higher ICC (50 μA max vs 40 μA) | Identical I²C and wired-OR use cases; minor difference in static current affects ultra-low-power battery systems | Select if TI supply chain alignment or dual-sourcing with TI-qualified processes is required |
| 74LVC05PW,118 | Lower VCC range (1.65 V to 5.5 V); faster tPLZ (19 ns max at 3.3 V); TSSOP14 package only | Better suited for 3.3 V-only systems; not suitable for 5 V bus interfacing due to 5.5 V absolute max rating | Choose when targeting compact PCB layout and 3.3 V domains exclusively - avoid for mixed 5 V/3.3 V designs |
Compared with SN74HC05DR, the 74HC05D,118 offers lower quiescent current and broader voltage support; versus 74LVC05PW,118, it trades speed for 5 V compatibility and SO14 footprint continuity - critical for legacy board redesigns.

FAQ
Can 74HC05D,118 be used without external pull-up resistors?
No. Its open-drain outputs cannot source current - they only sink. Without external pull-up resistors, outputs remain floating when inactive (high-impedance), causing undefined logic states and potential bus contention. Pull-up values depend on bus capacitance and speed requirements; 1 kΩ to 10 kΩ is typical for I²C at 100–400 kHz.
What is the maximum sink current per output at 5 V supply?
At VCC = 5.0 V and Tamb = +25 °C, the 74HC05D,118 guarantees 4.0 mA sink current with VOL ≤ 0.26 V. At VCC = 6.0 V and IO = 5.2 mA, VOL remains ≤ 0.4 V - confirming reliable low-state drive into standard pull-up loads.
Is 74HC05D,118 pin-compatible with 74LS05 or 74HCT05?
Yes, it shares identical SO14 pinout and logic function with 74LS05 and 74HCT05. However, unlike 74LS05 (TTL-input), it uses CMOS inputs requiring VIH ≥ 3.15 V at 4.5 V supply; unlike 74HCT05, it lacks TTL-compatible input thresholds - verify controller output levels before substitution.
Does 74HC05D,118 support hot-swap or live-insertion?
No. It lacks powered-off protection or Ioff specification. Applying input signals while VCC is unpowered may forward-bias internal clamping diodes, risking latch-up or damage. Always power VCC before asserting inputs - use power sequencing controls in hot-swap systems.
