Product details
Overview
74HC04BQ,115 from Nexperia is a CMOS hex inverter IC operating from 2.0 V to 6.0 V supply, delivering six independent logic-level inversion functions with propagation delay as low as 7 ns at VCC = 6.0 V and CL = 50 pF, input clamp diodes for overvoltage-tolerant interfacing, and guaranteed operation from –40 °C to +125 °C - used in digital signal conditioning, bus buffering, and clock waveform shaping in industrial control modules.
For engineers reviewing the 74HC04BQ,115 datasheet, 74HC04BQ,115 pinout, 74HC04BQ,115 application, or 74HC04BQ,115 equivalent, this page provides verified package mapping (DHVQFN14), terminal-level functional roles, static/dynamic electrical specifications across temperature, real-world use cases in level translation and noise-immune signal inversion, and validated alternative options for TTL- or CMOS-compatible hex inverter replacement.
Technical Context
This device implements six independent CMOS-based inverters in a single monolithic silicon die, each with symmetrical input thresholds (VIH = 0.7×VCC, VIL = 0.3×VCC for 74HC variant) and rail-to-rail output swing. Input clamp diodes allow safe interface to signals exceeding VCC when current-limited externally.
It operates within JEDEC-compliant voltage ranges (JESD7A), supports 50 pF capacitive loads, and exhibits low dynamic power dissipation (CPD = 21 pF) due to CMOS topology. The DHVQFN14 package enables high thermal efficiency and board-space savings versus SO14 or TSSOP14 variants.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 2.0 V to 6.0 V - Enables direct compatibility with 3.3 V and 5 V logic systems without level shifters. |
| Propagation Delay | 7 ns (typ) at VCC = 6.0 V, CL = 50 pF - Supports reliable timing in sub-100 MHz digital control paths. |
| Output Drive | ±25 mA per output - Sufficient to drive multiple standard CMOS inputs or small capacitive loads directly. |
| Input Thresholds | VIH = 4.2 V, VIL = 1.8 V at VCC = 6.0 V - Ensures robust noise immunity (>1.2 V DC noise margin). |
| Operating Temperature | –40 °C to +125 °C - Qualified for under-hood industrial and extended-temperature embedded applications. |
| Power Dissipation | 500 mW (max) with 9.6 mW/K derating above 98 °C - Thermal design accommodates sustained operation in compact enclosures. |
| ESD Rating | HBM >2000 V, CDM >1000 V - Reduces risk of field failure during handling and PCB assembly. |
Pinout & Package
DHVQFN14 (SOT762-1) package: leadless, 2.5 mm × 3.0 mm × 0.85 mm body, 14 terminals, exposed thermal pad (non-soldered by default), 0.5 mm pitch.
| 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 with rail-to-rail swing and ±25 mA sink/source capability. |
| 7 | GND | Primary ground reference (0 V); must be connected to system ground plane for stable operation. |
| 14 | VCC | Positive supply input; decoupling capacitor (100 nF) required within 5 mm for noise suppression. |
Key Features
| Feature | Design Value |
|---|---|
| Wide supply range | 2.0 V to 6.0 V - Eliminates need for separate voltage regulators in mixed-supply systems. |
| Input clamp diodes | Enables safe interface to signals up to VCC + 0.5 V using external current-limiting resistors. |
| Latch-up immunity | Exceeds 100 mA per JESD78 Class II Level B - Prevents destructive latch-up under transient overvoltage conditions. |
| High noise immunity | Typical 1.2 V DC noise margin at VCC = 6.0 V - Maintains logic integrity in electrically noisy industrial environments. |
| Thermal-enhanced package | DHVQFN14 (SOT762-1) offers lower θJA than SO14 or TSSOP14 - improves reliability in thermally constrained layouts. |
Applications
| Industrial PLC I/O Conditioning | Microcontroller GPIO Signal Inversion |
|---|---|
Use Scenario: Inverting sensor status signals before feeding into PLC input modules with fixed-active-high logic interpretation. IC Role / Device Role / Timing Role: Logic-level translator and polarity corrector; no timing-critical path, but requires stable DC inversion. Use Value: Eliminates need for discrete transistor inverters, reduces BOM count, and maintains signal integrity across long cable runs via high noise immunity. |
Use Scenario: Converting active-low reset or interrupt signals from peripherals to active-high levels compatible with MCU GPIO configuration. IC Role / Device Role / Timing Role: Level-shifting inverter with sub-10 ns delay - ensures deterministic edge alignment for time-sensitive firmware initialization. Use Value: Guarantees setup/hold compliance for MCU reset sequencing without adding propagation uncertainty from discrete solutions. |
| RS-232 Line Driver Interface | Crystal Oscillator Buffer Stage |
Use Scenario: Inverting TTL-level UART TX signals prior to RS-232 transceiver input to match polarity requirements of legacy line drivers. IC Role / Device Role / Timing Role: Polarity adapter between logic-level UART and transceiver IC; operates at baud rates ≤1 Mbps. Use Value: Provides clean, fast edge transitions and low output impedance to drive transceiver input capacitance without signal degradation. |
Use Scenario: Isolating and amplifying crystal oscillator output to drive multiple downstream clock domains while preserving waveform fidelity. IC Role / Device Role / Timing Role: Low-jitter buffer stage; uses one inverter pair in feedback configuration for gain, others for distribution. Use Value: Minimizes added phase noise (<0.5 ps RMS jitter contribution) and prevents loading-induced frequency drift in precision timing circuits. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar hex inverter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 74HC04PW,118 | TSSOP14 package (SOT402-1); 4.4 mm body width; 7.3 mW/K thermal derating above 81 °C. | Better suited for manual soldering or prototyping due to gull-wing leads; slightly higher θJA than DHVQFN14. | Select when board reworkability or test probe access is prioritized over thermal performance or footprint size. |
| 74HCT04BQ,115 | TTL-compatible inputs (VIH = 2.0 V min at VCC = 4.5 V); identical DHVQFN14 package and pinout. | Required when interfacing with legacy 5 V TTL outputs; not suitable for pure CMOS systems with <2.0 V logic highs. | Choose only if driving from 5 V TTL sources; otherwise, 74HC04BQ,115 provides superior noise margin in CMOS environments. |
Compared with 74HC04PW,118, the 74HC04BQ,115 offers 23 % lower thermal resistance and 35 % smaller footprint, enabling denser layouts; versus 74HCT04BQ,115, it delivers 1.4× higher DC noise margin at 5 V operation but lacks TTL input compatibility.

FAQ
Is the exposed pad on the DHVQFN14 package electrically connected?
No - the exposed thermal pad (terminal 1 index area) in the SOT762-1 package has no electrical function. It may remain floating or be connected to GND for thermal improvement, but soldering is optional and imposes no electrical requirement. Data sheet explicitly states "no electrical or mechanical requirement to solder the pad."
Can 74HC04BQ,115 drive a 100 pF load reliably?
Yes - although characterized at 50 pF, the device maintains valid logic levels and timing margins up to 100 pF. Propagation delay increases to ~32 ns at VCC = 6.0 V and CL = 100 pF (per extrapolation from tpd vs. CL curves), and output drive remains within ±25 mA limits. Decoupling and layout best practices are essential.
What is the maximum input voltage allowed when VCC = 0 V?
The absolute maximum input voltage is –0.5 V to VCC + 0.5 V. With VCC = 0 V, inputs must stay within –0.5 V to +0.5 V. Exceeding this risks damage via forward-biasing internal clamp diodes. For hot-plug or partial-power-down scenarios, external series resistors and clamping are recommended.
Does 74HC04BQ,115 support 1.8 V operation?
No - the minimum rated supply voltage is 2.0 V per JEDEC JESD7A. At 1.8 V, VIH/VIL thresholds become undefined, propagation delay exceeds specification, and output drive falls below guaranteed levels. For 1.8 V systems, consider Nexperia's 74LVC04 or similar 1.65–3.6 V logic families.
