Product details
Overview
74HC04DB,112 from Nexperia is a CMOS hex inverter IC operating from 2.0 V to 6.0 V supply, delivering six independent high-noise-immunity logic inversions with propagation delay as low as 7 ns at VCC = 6.0 V and CL = 50 pF, used for signal conditioning, level translation, and clock buffering in industrial control and embedded interface circuits.
For engineers reviewing the 74HC04DB,112 datasheet, 74HC04DB,112 pinout, 74HC04DB,112 application, or 74HC04DB,112 equivalent, key selection criteria include input voltage compatibility (CMOS-level), output drive capability (±25 mA), thermal performance in SSOP14 package, and static/dynamic characteristics across -40 °C to +125 °C.
Technical Context
This device implements six independent complementary MOS inverters on a single die, each with input clamp diodes enabling safe interfacing to voltages exceeding VCC when used with current-limiting resistors. Its logic function strictly follows the truth table: input LOW → output HIGH, input HIGH → output LOW.
The 74HC04DB,112 operates within JEDEC-compliant voltage ranges (JESD7A: 2.0–6.0 V) and meets stringent ESD robustness requirements (HBM >2000 V, CDM >1000 V). It exhibits rail-to-rail output swing and maintains stable VIH/VIL thresholds across temperature and supply voltage variations.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.0 V to 6.0 V - Enables direct integration into mixed-voltage systems including 3.3 V and 5 V logic domains. |
| Propagation Delay (tpd) | 7 ns (VCC = 6.0 V, CL = 50 pF) - Supports reliable operation in high-speed digital timing paths up to ~70 MHz. |
| Output Drive Current | ±25 mA - Sufficient to directly drive multiple standard TTL or CMOS inputs without external buffers. |
| Input Thresholds (VIH/VIL) | VIH = 4.2 V, VIL = 1.8 V @ VCC = 6.0 V - Ensures robust noise margin (>1.6 V) in noisy industrial environments. |
| Operating Temperature | -40 °C to +125 °C - Qualified for under-hood, motor control, and industrial automation applications. |
| Power Dissipation (Ptot) | 500 mW (SO14), derates linearly above 100 °C - Supports sustained operation in thermally constrained PCB layouts. |
| ESD Protection | HBM >2000 V, CDM >1000 V - Reduces risk of field failure during handling and system integration. |
Pinout & Package
74HC04DB,112 is supplied in SSOP14 (SOT337-1) package - plastic shrink small outline package, 14 leads, body width 5.3 mm, pitch 0.65 mm. Note: This package was removed from latest revision (v.10) but remains orderable per legacy part marking; pinout matches SO14 (SOT108-1) mechanical layout.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 3, 5, 9, 11, 13 | Input (1A–6A) | CMOS-compatible logic inputs accepting 0 V to VCC; include internal clamp diodes for overvoltage protection. |
| 2, 4, 6, 8, 10, 12 | Output (1Y–6Y) | Inverted logic outputs capable of sourcing/sinking ±25 mA; rail-to-rail swing with defined VOH/VOL. |
| 7 | GND | Reference ground terminal (0 V); must be connected to system ground plane for stable noise immunity. |
| 14 | VCC | Primary power supply input; decoupling capacitor (100 nF) required within 10 mm for transient suppression. |
Key Features
| Feature | Design Value |
|---|---|
| Wide Supply Range | 2.0–6.0 V operation enables drop-in use across 3.3 V and 5 V systems without level shifters. |
| High Noise Immunity | Typical noise margin >1.6 V at VCC = 6.0 V ensures reliable switching in electrically noisy factory environments. |
| Latch-up Robustness | Exceeds 100 mA per JESD78 Class II Level B - prevents destructive latch-up during transient overcurrent events. |
| Thermal Stability | Specified from -40 °C to +125 °C with no parameter degradation - supports extended-life deployment in sealed enclosures. |
| Low Static Power | ICC ≤ 40 μA at VCC = 6.0 V and TA = +125 °C - minimizes standby power in battery-backed or energy-sensitive designs. |
Applications
| Industrial PLC I/O Conditioning | Microcontroller GPIO Signal Inversion |
|---|---|
Use Scenario: Inverting sensor status signals (e.g., limit switch closure) before feeding into PLC input modules with active-HIGH logic expectations. IC Role / Device Role / Timing Role: Logic-level translation and polarity correction between mechanical sensors and programmable controller inputs. Use Value: Eliminates need for external pull-up networks or discrete transistor inverters, reducing BOM count and board area by 60%. |
Use Scenario: Driving LED indicators with active-LOW logic while preserving microcontroller GPIO polarity for firmware consistency. IC Role / Device Role / Timing Role: Dedicated signal inversion stage isolating MCU pin behavior from peripheral electrical requirements. Use Value: Enables simultaneous use of same GPIO for both push-pull output and open-drain emulation without software rework. |
| RS-232 Line Driver Interface | Digital Clock Signal Buffering |
Use Scenario: Inverting TTL-level UART TX signals prior to RS-232 transceiver input to meet driver polarity requirements. IC Role / Device Role / Timing Role: Polarity alignment stage ensuring correct logic mapping between UART peripheral and line driver IC. Use Value: Avoids timing skew introduced by software-based bit inversion, maintaining full-duplex throughput integrity. |
Use Scenario: Distributing and inverting a master clock signal to synchronize dual synchronous logic blocks with opposite edge-triggering needs. IC Role / Device Role / Timing Role: Low-skew clock buffer providing phase-complementary timing references. Use Value: Achieves sub-nanosecond inter-output skew (<0.5 ns) critical for DDR memory interface timing alignment. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar hex inverter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 74HC04D,118 | SO14 package (SOT108-1); identical electrical specs; 3.9 mm body width vs. 5.3 mm SSOP. | Lower profile not required; PCB space less constrained; preferred for through-hole prototyping or legacy footprint reuse. | Select when mechanical compatibility with standard SOIC footprints is mandatory and thermal load is moderate. |
| 74HC04PW,118 | TSSOP14 package (SOT402-1); same logic and timing; 4.4 mm body width; 0.65 mm pitch; higher thermal resistance than SSOP. | Used where board density demands thinner profile than SO14 but SSOP reflow process is unavailable. | Choose for automated assembly lines equipped for TSSOP but lacking SSOP stencil support or reflow profiling. |
Compared with 74HC04DB,112, the SO14 variant offers easier hand-soldering and lower thermal resistance, while the TSSOP version provides superior board-area efficiency at the cost of tighter placement tolerances and reduced power handling.

FAQ
Is 74HC04DB,112 pin-compatible with 74HC04D (SO14)?
Yes - 74HC04DB,112 uses the same 14-pin functional pinout as 74HC04D: inputs on pins 1/3/5/9/11/13, outputs on 2/4/6/8/10/12, GND on pin 7, and VCC on pin 14. Mechanical dimensions differ (SSOP vs SO14), so PCB footprint is not interchangeable without layout revision.
What is the maximum output current per inverter channel?
Each inverter output can source or sink up to ±25 mA continuously under recommended operating conditions. Absolute maximum clamping current is ±20 mA, but sustained operation above ±20 mA requires thermal derating per the 500 mW total package limit and ambient temperature.
Does 74HC04DB,112 support 3.3 V logic systems?
Yes - it operates reliably from 2.0 V to 6.0 V, with guaranteed VIH ≥ 2.1 V and VIL ≤ 1.35 V at VCC = 3.3 V. Input thresholds scale with supply voltage, ensuring full noise margin and clean switching in 3.3 V systems.
Can 74HC04DB,112 drive a 50 pF capacitive load at 10 MHz?
Yes - with tpd = 9 ns at VCC = 4.5 V and CL = 50 pF, the device supports signal edges well within 10 MHz period (100 ns), delivering adequate setup/hold margins. Total dynamic power (PD = CPD × VCC² × fi × N) remains below 1 mW at this frequency.
