Product details
Overview
MC74HC04ADR2 from onsemi is a high-performance silicon-gate CMOS hex inverter IC containing six independent three-stage inverters in a 14-pin SOIC package. It operates from 2.0 V to 6.0 V, delivers 10 LSTTL load drive capability, and supports industrial temperature range (−55 °C to +125 °C). It is used for logic-level inversion, signal conditioning, and clock buffering in digital control subsystems.
For engineers reviewing the MC74HC04ADR2 datasheet, pinout, applications, or equivalent options, key selection criteria include supply voltage compatibility (2.0–6.0 V), propagation delay (13 ns at 6.0 V), input leakage current (±1.0 µA), output drive strength, and AEC-Q100 qualification status for automotive-grade variants.
Technical Context
The MC74HC04ADR2 implements six identical CMOS inverter stages with three-transistor topology per stage, enabling rail-to-rail output swing and high noise immunity. Its inputs are compatible with standard CMOS outputs and-when pulled up-are compatible with LSTTL outputs.
It features low quiescent supply current (40 µA max at 125 °C), 10 pF maximum input capacitance, and propagation delays specified across full voltage (2.0–6.0 V) and temperature (−55 °C to +125 °C) ranges. The device meets JEDEC Standard No. 7A and is Pb-free, halogen-free, and RoHS compliant.

IC Role / Device Role / Timing Role: Signal polarity correction and noise filtering via Schmitt-trigger-capable input structure (inherent in HC series). Use Value: Eliminates external discrete inverters and pull-up resistors; reduces BOM count and PCB area while maintaining AEC-Q100 compliance. | Use Scenario: Driving LED indicators and relay coils from 5 V MCU outputs where inverted logic is required for fail-safe activation. IC Role / Device Role / Timing Role: Level-shifting and current boosting buffer between MCU GPIO and higher-current loads. Use Value: Delivers 5.2 mA sink/source per output at 5 V - sufficient to drive common automotive LEDs and small relays without external transistors. |
| Medical Equipment Power Sequencing | Test & Measurement Instrument Clock Buffering |
Use Scenario: Generating complementary enable/disable signals for sequential power-up of analog front-end and digital processing sections. IC Role / Device Role / Timing Role: Synchronized logic inversion with matched propagation delay across all six channels. Use Value: Ensures deterministic timing skew <1 ns between outputs - critical for avoiding race conditions in multi-rail power controllers. | Use Scenario: Cleaning up and distributing square-wave clock signals from a crystal oscillator to multiple FPGA clock inputs. IC Role / Device Role / Timing Role: Low-jitter, low-skew clock inversion and fan-out buffer. Use Value: Propagation delay variation ≤3 ns across all six inverters at 5 V - preserves edge alignment for synchronous sampling systems. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar hex inverter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74HC04DR | Same logic function, 14-pin SOIC, but TI-specified AC/DC parameters differ slightly: tPLH max = 15 ns at 6 V vs. 13 ns for MC74HC04ADR2; ICC max = 20 µA at 25 °C (vs. 1.0 µA for onsemi). | Valid for non-automotive commercial designs where 2 ns delay penalty and higher room-temp ICC are acceptable. | Select SN74HC04DR only if sourcing from TI's authorized channel is required; verify timing margins in final layout. |
| 74HC04PW,118 | NXP variant in TSSOP-14 package; identical DC specs but 150 °C/W thermal resistance (vs. 116 °C/W for SOIC); CPD = 20 pF (same). | Suitable for space-constrained boards where footprint reduction outweighs thermal derating needs. | Prefer 74HC04PW,118 only when PCB real estate is critical and ambient temperature remains <85 °C. |
Compared with SN74HC04DR and 74HC04PW,118, the MC74HC04ADR2 offers the lowest propagation delay at 6 V, tightest ICC specification over temperature, and SOIC-14 package optimized for thermal performance and legacy compatibility - making it preferred for timing-critical and automotive-qualified designs.

FAQ
What is the maximum operating supply voltage for MC74HC04ADR2?
The MC74HC04ADR2 supports a DC supply voltage range of 2.0 V to 6.0 V. Absolute maximum rating is 6.5 V, but operation above 6.0 V voids parametric guarantees and risks reliability degradation. At 6.0 V, the device achieves its fastest propagation delay (13 ns) and highest noise margin, making it ideal for 5 V legacy systems requiring precise timing.
Does MC74HC04ADR2 support direct interface with TTL logic inputs?
Yes, MC74HC04ADR2 inputs are compatible with standard CMOS outputs and - when externally pulled up with a resistor - interface directly with LSTTL outputs. Its VIH minimum is 4.20 V at VCC = 6.0 V, satisfying TTL high-level input requirements. However, for guaranteed TTL compatibility without pull-ups, the pin-compatible MC74HCT04ADR2 variant (5 V only) is recommended.
Is MC74HC04ADR2 qualified for automotive applications?
The MC74HC04ADR2 itself is not automotive-qualified; however, the −Q suffix variant (e.g., MC74HC04ADR2G−Q*) is AEC-Q100 qualified and PPAP capable. The base MC74HC04ADR2 shares identical electrical and thermal specifications but lacks the controlled manufacturing site, change control, and test documentation required for automotive deployment.
What is the thermal resistance (θJA) of the MC74HC04ADR2 package?
The MC74HC04ADR2 uses the SOIC−14 (Case 751A) package with a thermal resistance θJA of 116 °C/W, measured on a standard FR4 board with minimum pad spacing and no airflow (per JESD51−7). This value assumes proper PCB copper pour and decoupling - actual board-level θJA may improve to ~70 °C/W with 2 oz copper and thermal vias.
Can unused inputs on MC74HC04ADR2 be left floating?
No. Unused inputs on MC74HC04ADR2 must be tied to a valid logic level - either VCC or GND - to prevent oscillation, increased power consumption, and potential damage due to undefined bias conditions. The datasheet explicitly states that floating inputs violate recommended operating conditions and may cause erratic behavior, especially at temperature extremes or under EMI stress.
