Product details
Overview
74HCT04D,652 from Nexperia is a hex inverter IC with TTL-compatible inputs, 14-pin SO14 (SOT108-1) package, operating from 4.5 V to 5.5 V supply, −40 °C to +125 °C temperature range, and 10 ns typical propagation delay at VCC = 4.5 V - used for logic-level inversion in industrial control bus interfaces and microcontroller I/O conditioning.
For engineers reviewing the 74HCT04D,652 datasheet, 74HCT04D,652 pinout, 74HCT04D,652 application, or 74HCT04D,652 equivalent, key selection considerations include TTL input threshold compatibility (VIH = 2.0 V min), output drive capability (±4.0 mA), SO14 thermal derating (10.1 mW/K above 100 °C), and ESD robustness (HBM >2000 V).
Technical Context
This device implements six independent CMOS inverters with Schmitt-trigger–free TTL-compatible input thresholds (VIH ≥ 2.0 V, VIL ≤ 0.8 V at VCC = 4.5–5.5 V) and rail-to-rail complementary output stages. Each inverter features input clamp diodes enabling safe interfacing to voltages exceeding VCC when current-limited.
It operates within JEDEC JESD7A compliance (2.0–6.0 V), supports mixed-voltage system interfacing via its 5 V–tolerant inputs, and delivers guaranteed VOL ≤ 0.4 V and VOH ≥ 3.7 V under 4.0 mA load - critical for noise-immune signal restoration in noisy industrial environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 4.5 V to 5.5 V - ensures compatibility with standard 5 V TTL and mixed-signal systems without level-shifting. |
| Propagation Delay | 10 ns (typ) at VCC = 4.5 V, CL = 50 pF - enables reliable timing in sub-100 MHz digital control paths. |
| Output Drive | ±4.0 mA - sufficient to directly drive multiple 74-series inputs or small capacitive loads (<30 pF) without buffering. |
| Input Thresholds | VIH = 2.0 V min, VIL = 0.8 V max - matches legacy TTL logic families for seamless integration into retrofitted or hybrid designs. |
| Operating Temperature | −40 °C to +125 °C - qualified for under-hood automotive modules, industrial PLC backplanes, and high-ambient embedded controllers. |
| ESD Protection | HBM >2000 V, CDM >1000 V - reduces field failure risk during manual handling and board assembly in non-EPA environments. |
| Power Dissipation | 500 mW max (SO14), derates 10.1 mW/K above 100 °C - defines thermal margin for continuous operation in sealed enclosures. |
Pinout & Package
74HCT04D,652 uses the SO14 (SOT108-1) plastic small outline package: 14-lead, 3.9 mm body width, 1.27 mm lead pitch, and gull-wing surface-mount terminals. Thermal resistance θJA = 100 K/W (typ) per JEDEC MS-012.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 3, 5, 9, 11, 13 | Input (1A–6A) | Independent TTL-level logic inputs; each includes clamp diodes for overvoltage protection up to ±20 mA. |
| 2, 4, 6, 8, 10, 12 | Output (1Y–6Y) | Inverted CMOS outputs capable of sourcing/sinking 4.0 mA while maintaining VOH ≥ 3.7 V / VOL ≤ 0.4 V. |
| 7 | GND | Primary ground reference; all internal logic and I/O referenced to this node; requires low-impedance PCB connection. |
| 14 | VCC | Positive supply rail; must be decoupled locally with ≥100 nF ceramic capacitor to suppress switching noise. |
Key Features
| Feature | Design Value |
|---|---|
| TTL-compatible input levels | VIH ≥ 2.0 V and VIL ≤ 0.8 V at 4.5–5.5 V - eliminates need for external level shifters when interfacing with legacy 5 V microcontrollers or FPGAs. |
| Wide temperature range | −40 °C to +125 °C operation - supports deployment in engine control units, motor drives, and outdoor telecom equipment without derating. |
| Input clamp diodes | Enables safe interface to signals up to VCC + 0.5 V using series current-limiting resistors - simplifies design of mixed-voltage sensor interfaces. |
| Low dynamic power | CPD = 24 pF - limits switching power to <1.5 mW at 1 MHz with 5 V supply, reducing thermal load in dense logic arrays. |
| High noise immunity | Typical noise margin >1.2 V at VCC = 5 V - prevents false triggering in electrically noisy factory-floor or automotive harness environments. |
Applications
| Industrial PLC I/O Conditioning | Microcontroller GPIO Inversion |
|---|---|
|
Use Scenario: Inverting open-collector sensor outputs (e.g., NPN proximity switches) before feeding into 3.3 V MCU GPIO pins with weak pull-ups. IC Role / Device Role / Timing Role: Signal polarity correction and voltage translation via TTL-input compatibility and rail-to-rail CMOS output swing. Use Value: Eliminates discrete transistor inverters and level-shifters, reducing BOM count by 6× per channel and improving layout density. |
Use Scenario: Driving active-low enable lines on multiple peripheral ICs (e.g., ADCs, DACs, UART transceivers) from a single MCU GPIO. IC Role / Device Role / Timing Role: Fan-out buffer and logic inversion stage; six independent channels allow parallel control of diverse peripherals. Use Value: Enables single-pin control of six devices with guaranteed 10 ns timing margin, avoiding software-based bit-banging delays. |
| Legacy Bus Interface Logic | Test Equipment Signal Generation |
|
Use Scenario: Converting TTL-level address strobes and control signals between vintage 8-bit CPUs (e.g., Z80, 6502) and modern FPGA-based glue logic. IC Role / Device Role / Timing Role: Bidirectional logic-level adaptation and waveform sharpening for marginal edge rates on aging bus traces. Use Value: Restores clean 5 V logic edges degraded by long PCB traces or capacitive loading, extending functional life of legacy systems. |
Use Scenario: Generating complementary clock or trigger signals for automated test fixtures requiring precise phase inversion. IC Role / Device Role / Timing Role: Low-skew inverter pair for creating true/complement signal pairs with matched propagation delay (Δtpd < 1 ns). Use Value: Achieves sub-nanosecond skew between inverted/non-inverted outputs - critical for jitter-sensitive timing calibration circuits. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar hex inverter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 74HC04D,652 | CMOS input thresholds (VIH = 3.15 V min at VCC = 4.5 V); wider 2.0–6.0 V supply range | Better suited for 3.3 V–5 V mixed-supply systems where input voltage may vary across rails | Select when interfacing with CMOS outputs or battery-powered subsystems needing lower VCC flexibility |
| SN74HCT04DR | TI's SO14 variant; identical VIH/VIL specs but higher ICC (max 40 μA vs. 20 μA) and slightly slower tpd (12 ns typ) | Validated for TI-specific reference designs and automotive AEC-Q100–qualified variants exist | Prefer when designing to TI ecosystem documentation or requiring AEC-Q100 Grade 2 qualification |
Compared with 74HC04D,652 and SN74HCT04DR, the 74HCT04D,652 offers optimal balance of TTL compatibility, low static current (2 μA typ), and fast propagation (10 ns typ), making it ideal for cost-sensitive industrial controls where strict 5 V interoperability and minimal power overhead are required.

FAQ
Can 74HCT04D,652 operate at 3.3 V supply?
No - the 74HCT04 variant is specified only for 4.5 V to 5.5 V operation. At 3.3 V, input thresholds fall outside TTL specification (VIH would be <1.8 V), risking unreliable logic recognition. Use 74HC04D,652 instead for 3.3 V systems.
What is the maximum capacitive load this device can drive reliably?
At VCC = 5 V and Tamb = 25 °C, 74HCT04D,652 maintains 10 ns propagation delay up to 50 pF load capacitance. For loads >50 pF, transition times increase linearly; beyond 100 pF, setup/hold margins may be violated in synchronous designs.
Is pin 14 (VCC) internally decoupled?
No - the device has no internal bypass capacitance. A minimum 100 nF X7R ceramic capacitor must be placed between pin 14 and pin 7 (GND) within 5 mm of the package to suppress supply bounce during simultaneous output switching.
Does this part support hot-swap insertion?
No - 74HCT04D,652 lacks hot-swap protection circuitry. Applying VCC before GND or connecting inputs while VCC is absent risks latch-up due to forward-biased clamp diodes. Always power GND first and sequence VCC before signal application.
