Product details
Overview
MC74HC04AD 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 −55 °C to +125 °C operation - used for logic-level translation, signal conditioning, and clock buffering in industrial control and embedded timing circuits.
For engineers reviewing the MC74HC04AD datasheet, pinout, applications, or equivalent options, key selection criteria include supply voltage range (2.0–6.0 V), propagation delay (13–110 ns depending on VCC), input leakage current (±1.0 µA), output drive strength, and AEC-Q100 qualification status for automotive-qualified variants.
Technical Context
The MC74HC04AD implements six identical CMOS inverter stages with three-transistor topology per gate, enabling rail-to-rail output swing and high noise immunity. Its inputs are compatible with standard CMOS outputs and, with pullup resistors, with LSTTL outputs - supporting mixed-logic interfacing without level shifters.
It features low quiescent supply current (≤40 µA at 6.0 V), maximum input capacitance of 10 pF, and power dissipation capacitance of 20 pF per inverter - making it suitable for low-power digital systems where static current and capacitive loading must be tightly controlled.

Equivalent & Alternatives
The following parts are listed as comparable options for similar hex inverter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74HC04DR | TI part with identical pinout, 2.0–6.0 V range, and 13 ns tPLH at 6 V; slightly higher ICC (50 µA max vs. 40 µA) | Not AEC-Q100 qualified; rated only to +85 °C commercial grade | Select when cost sensitivity outweighs automotive qualification and extended temperature needs |
| 74VHC04M | ON Semiconductor VHC variant with faster 7.5 ns propagation at 5 V but narrower 2.0–5.5 V range and higher input capacitance (12 pF) | Higher speed suits high-frequency clock fanout but less tolerant of 6 V legacy systems | Select when sub-10 ns delay is critical and supply is strictly regulated at 5 V |
Compared with SN74HC04DR and 74VHC04M, the MC74HC04AD offers the broadest supply range (2.0–6.0 V), widest temperature rating (−55 °C to +125 °C), and AEC-Q100 qualification - making it the preferred choice for automotive and harsh-environment industrial deployments where reliability and voltage flexibility are non-negotiable.

FAQ
What is the maximum operating temperature for the MC74HC04AD?
The MC74HC04AD is rated for operation from −55 °C to +125 °C, meeting extended industrial and automotive-grade requirements. This specification is validated per JEDEC JESD22-A108 and confirmed in the device's Recommended Operating Conditions table. The MC74HC04AD maintains full logic functionality and parametric compliance across this full range without derating.
Does the MC74HC04AD support 3.3 V logic systems?
Yes, the MC74HC04AD fully supports 3.3 V operation: its guaranteed supply range (2.0–6.0 V) includes 3.3 V, and all DC and AC parameters - including VIH (≥2.10 V), VOL (≤0.26 V at 2.4 mA), and tPLH (30 ns typical) - are specified at VCC = 3.0 V. The MC74HC04AD interfaces directly with 3.3 V CMOS and LVTTL without level-shifting circuitry.
Is the MC74HC04AD pin-compatible with older 74LS04 devices?
Yes, the MC74HC04AD is explicitly stated in its datasheet to be identical in pinout to the 74LS04 and MC14069. All six inverter inputs (pins 1, 3, 5, 9, 11, 13) and outputs (pins 2, 4, 6, 8, 10, 12) map one-to-one, with pin 7 as GND and pin 14 as VCC. This enables drop-in replacement in existing LS04 layouts, provided supply voltage and loading conditions are updated per HC specifications.
What is the ESD rating of the MC74HC04AD?
The MC74HC04AD has an ESD withstand voltage >2000 V per the Human Body Model (HBM), tested per EIA/JESD22-A114-A. It does not specify Charged Device Model (CDM) rating in the provided datasheet. This HBM rating exceeds standard industrial requirements and supports safe handling in uncontrolled assembly environments when proper grounding protocols are followed.
Can unused inputs on the MC74HC04AD be left floating?
No - unused inputs on the MC74HC04AD must never be left floating. Per the datasheet's Note 3 in the Recommended Operating Conditions section, all unused inputs must be tied to a valid logic level (either VCC or GND) to prevent increased supply current, oscillation, or unpredictable output states. Floating CMOS inputs can draw excessive current and cause localized heating or logic contention.
