Product details
Overview
74HCT04N,652 from Nexperia is a TTL-compatible hex inverter IC with six independent CMOS inverter gates, operating from 4.5 V to 5.5 V supply, delivering 4.32 V VOH at -4.0 mA load and 0.26 V VOL at 5.2 mA sink current, used for logic-level inversion and signal conditioning in digital control subsystems.
For engineers reviewing the 74HCT04N,652 datasheet, 74HCT04N,652 pinout, 74HCT04N,652 application, or 74HCT04N,652 equivalent, this page delivers verified electrical specs, SO14 package details, real-world use cases, and validated alternative parts - all grounded in Nexperia's Rev. 10 (2024) product data sheet.
Technical Context
The 74HCT04N,652 implements six independent CMOS inverters with TTL-compatible input thresholds (VIH = 2.0 V min, VIL = 0.8 V max at VCC = 4.5–5.5 V), enabling direct interfacing with legacy 5 V TTL logic families without level-shifting. Its inputs include clamp diodes supporting current-limiting resistor protection against overvoltage.
It operates across -40 °C to +125 °C, meets JESD7A (2.0–6.0 V) and JESD8C (2.7–3.6 V) standards, and features ESD robustness per HBM (>2000 V) and CDM (>1000 V), with latch-up immunity exceeding 100 mA per JESD78 Class II Level B.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 4.5 V to 5.5 V - ensures compatibility with standard 5 V TTL systems and stable operation under rail variation. |
| Propagation Delay | 19 ns max at VCC = 4.5 V, CL = 50 pF - supports reliable timing in medium-speed digital control paths up to ~25 MHz. |
| Output Drive | ±4.0 mA (source), ±5.2 mA (sink) - sufficient to drive multiple 74-series TTL inputs or small capacitive loads (<50 pF). |
| Input Thresholds | VIH ≥ 2.0 V, VIL ≤ 0.8 V - guarantees unambiguous recognition of TTL HIGH/LOW levels across temperature. |
| Operating Temperature | -40 °C to +125 °C - qualified for industrial and extended-temperature embedded applications. |
| Power Dissipation | 500 mW max (SO14 package) - enables continuous operation in compact PCB layouts with moderate airflow. |
| Input Capacitance | 3.5 pF - minimizes loading on upstream drivers and preserves signal edge integrity. |
Pinout & Package
74HCT04N,652 is supplied in the SO14 (SOT108-1) plastic small outline package: 14-pin, 3.9 mm body width, 1.27 mm lead pitch, with gull-wing leads and standard JEDEC MS-012 footprint.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 3, 5, 9, 11, 13 | Data Input (1A–6A) | Independent TTL-compatible logic inputs for each of six inverter stages. |
| 2, 4, 6, 8, 10, 12 | Data Output (1Y–6Y) | Inverted logic outputs, each capable of sourcing/sinking ≥4 mA at full rail. |
| 7 | GND | Ground reference for all logic and power domains; must be low-impedance connection. |
| 14 | VCC | Main supply input (4.5–5.5 V); decoupling capacitor (100 nF) required near this pin. |
Key Features
| Feature | Design Value |
|---|---|
| TTL-Compatible Inputs | Enables plug-in replacement of 74LS04 in legacy 5 V systems without redesign or level shifters. |
| Clamp Diode Protection | Allows external current-limiting resistors to safely interface inputs to voltages > VCC (e.g., 12 V sensor signals). |
| High Noise Immunity | Guaranteed 0.4 V noise margin at VCC = 5 V, reducing susceptibility to crosstalk in dense digital layouts. |
| Wide Temp Range | Specified from -40 °C to +125 °C - suitable for under-hood, factory automation, and outdoor electronics. |
| Low Static Current | ICC ≤ 40 μA at VCC = 5.5 V and full temperature range - ideal for always-on control logic. |
Applications
| Industrial PLC I/O Conditioning | Microcontroller GPIO Signal Inversion |
|---|---|
Use Scenario: Inverting enable/disable signals between a 5 V microcontroller and 24 V industrial relay modules using optocoupler interfaces. IC Role / Device Role / Timing Role: Logic-level translator and signal polarity corrector, ensuring active-low relay activation matches MCU firmware logic. Use Value: Eliminates need for discrete transistor inverters; reduces BOM count and layout area while maintaining deterministic 19 ns propagation delay. |

IC Role / Device Role / Timing Role: Pin-compatible functional upgrade delivering lower power and higher noise immunity than bipolar TTL. Use Value: Extends system service life without PCB rework; maintains identical timing behavior (19 ns max vs. LS04's 15 ns) for backward compatibility. |
Use Scenario: Inverting PWM signals to drive common-anode LED arrays requiring active-low enable control from a microcontroller. IC Role / Device Role / Timing Role: Single-gate inverter stage dedicated to polarity reversal of high-frequency PWM (≤1 MHz). Use Value: Preserves PWM fidelity with <20 ns propagation delay and <20 ns transition time, avoiding duty-cycle distortion. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar hex inverter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 74HCT04D,652 | Same logic function and specs, but in SO14 package with different suffix coding (no 'N'); identical pinout and thermal profile. | No difference - fully interchangeable in SO14-based designs; differs only in ordering code and traceability marking. | Select when standard SO14 reel packaging or alternate logistics tracking is required. |
| SN74HCT04DR | TI part with same 4.5–5.5 V operation, VIH/VIL thresholds, and 19 ns tpd, but rated only to +85 °C (vs. +125 °C for 74HCT04N,652). | Suitable for commercial-grade applications; not recommended for extended-temperature industrial deployments. | Choose for cost-sensitive consumer electronics where ambient temperature remains below 70 °C. |
Compared with 74HCT04D,652, the 74HCT04N,652 offers identical functionality with manufacturer-specific traceability; versus SN74HCT04DR, it provides guaranteed operation up to +125 °C - critical for thermally demanding environments where TI's industrial temp grade is insufficient.

FAQ
What is the maximum operating temperature for the 74HCT04N,652?
The 74HCT04N,652 is fully specified from -40 °C to +125 °C per Nexperia's Rev. 10 datasheet. This extended temperature range allows deployment in harsh environments such as industrial motor drives, outdoor communication nodes, and under-hood automotive ECUs where ambient heat exceeds +85 °C.
Is the 74HCT04N,652 pin-compatible with the 74LS04?
Yes, the 74HCT04N,652 uses the standard 14-pin DIP/SO14 pinout matching the 74LS04, including identical placement of VCC (pin 14), GND (pin 7), and all six inverter input/output pairs. This enables direct replacement in legacy 5 V TTL designs without PCB modification.
Does the 74HCT04N,652 require external pull-up or pull-down resistors on unused inputs?
No - unused inputs on the 74HCT04N,652 must be tied to VCC or GND to prevent floating states and excessive ICC. The device does not integrate internal pull resistors; leaving inputs unconnected risks increased power consumption and erratic output behavior due to noise coupling.
What is the typical propagation delay of the 74HCT04N,652 at 5 V supply?
At VCC = 5.0 V with CL = 15 pF, the 74HCT04N,652 exhibits a typical propagation delay (tpd) of 8 ns (per Nexperia Table 7). Under worst-case conditions (VCC = 4.5 V, CL = 50 pF, +125 °C), the maximum tpd is 29 ns - ensuring predictable timing in synchronous digital subsystems.
Can the 74HCT04N,652 safely interface with 12 V signals?
Yes - the 74HCT04N,652 inputs include integrated clamp diodes. When used with an external current-limiting resistor (e.g., 10 kΩ), it can accept input voltages up to 12 V without damage, making it suitable for interfacing with higher-voltage sensors or industrial fieldbus signals while maintaining logic-level compatibility.
