Product details
Overview
MC74HC04AFL2 from onsemi is a high-performance silicon-gate CMOS hex inverter IC containing six independent three-stage inverters in a 14-lead SOIC-EIAJ package. It operates from 2.0 V to 6.0 V, delivers ±25 mA output drive per pin, exhibits 1 µA max input leakage at 6 V, and supports industrial temperature range (–55 °C to +125 °C). It interfaces directly with CMOS, NMOS, and TTL logic families and is used in digital signal conditioning, clock buffering, and level translation circuits.
For engineers reviewing the MC74HC04AFL2 datasheet, pinout, applications, or equivalent options, key selection criteria include its 2–6 V supply range, 13 ns propagation delay at 6 V, 10 LSTTL load drive capability, JEDEC Std. 7A compliance, and compatibility with LS04 and MC14069 pinouts.
Technical Context
The MC74HC04AFL2 implements six identical CMOS inverter stages using three-stage transistor-level design for optimized noise immunity and switching performance. Each inverter features rail-to-rail output swing, input thresholds defined as VIH = 0.7×VCC and VIL = 0.3×VCC, and guaranteed operation across –55 °C to +125 °C with supply voltage from 2.0 V to 6.0 V.
Its architecture enables direct interfacing between mixed-logic families without external level shifters: inputs accept standard CMOS outputs natively and LSTTL outputs when pulled up, while outputs drive 10 LSTTL loads or directly interface with CMOS/NMOS/TTL inputs under all specified operating conditions.

Use Value: Eliminates need for dedicated level translators; supports 10 LSTTL loads per output with guaranteed VIH/VIL thresholds. | Use Scenario: Isolating and amplifying low-power crystal oscillator outputs (e.g., from Pierce gate oscillators) to drive multiple downstream clock domains. IC Role / Device Role / Timing Role: Clock buffer - provides low-jitter, full-swing buffered clock signal with matched propagation delays across channels. Use Value: Reduces clock skew and improves jitter performance due to matched tPLH/tPHL (≤3 ns variation across six inverters at same VCC/temperature). |
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, same 2–6 V range and 13 ns delay at 6 V, but rated only to +85 °C (vs. +125 °C for MC74HC04AFL2). | Not qualified for extended-temperature industrial or automotive under-hood use. | Select MC74HC04AFL2 when operation beyond +85 °C is required; SN74HC04DR suffices for commercial-grade PCBs. |
| 74HC04PW,118 | Nexperia TSSOP-14 variant with same electrical specs but different package (4.4 mm × 5.0 mm vs. SOIC-EIAJ 3.9 mm × 9.9 mm) and moisture sensitivity level (MSL3 vs. MSL1). | Requires reflow profile adjustment and board layout change; not drop-in compatible mechanically. | Choose MC74HC04AFL2 for SOIC-EIAJ footprint continuity and MSL1 handling; use 74HC04PW,118 only if space-constrained layout mandates TSSOP. |
Compared with SN74HC04DR and 74HC04PW,118, the MC74HC04AFL2 offers superior thermal qualification (–55 °C to +125 °C), mechanical compatibility with legacy LS04 footprints, and MSL1 reliability-making it optimal for long-lifecycle industrial and automotive control modules where ambient temperature and assembly robustness are critical.

FAQ
What is the maximum operating temperature for the MC74HC04AFL2?
The MC74HC04AFL2 is rated for continuous operation from –55 °C to +125 °C across all package variants, including the SOIC-EIAJ (Case 940A-03) used in the MC74HC04AFL2. This specification is verified per JEDEC Std. 7A and confirmed in the device's Recommended Operating Conditions table, making it suitable for under-hood automotive and industrial motor-control applications where ambient temperatures exceed +85 °C.
Does the MC74HC04AFL2 support 3.3 V logic systems?
Yes, the MC74HC04AFL2 fully supports 3.3 V operation: its guaranteed operating voltage range is 2.0 V to 6.0 V, and all DC and AC specifications-including VIH = 2.1 V min, VIL = 0.9 V max, VOH ≥ 3.2 V, and VOL ≤ 0.33 V at 4 mA-are explicitly validated at VCC = 3.3 V in the datasheet's DC Characteristics tables. It is widely deployed in mixed-voltage 3.3 V/5 V systems.
Is the MC74HC04AFL2 pin-compatible with the 74LS04?
Yes, the MC74HC04AFL2 is explicitly stated to be identical in pinout to the 74LS04 and MC14069. Pin assignments for inputs (A1–A6), outputs (Y1–Y6), VCC (pin 14), and GND (pin 7) match exactly. However, note that while pinout is identical, electrical characteristics differ: MC74HC04AFL2 draws µA-level input current versus mA-level for LS04, and requires no external pull-ups for CMOS driving but may need them for LSTTL input compatibility.
What is the typical propagation delay of the MC74HC04AFL2 at 5 V?
At VCC = 5.0 V, the typical propagation delay (tPLH/tPHL) of the MC74HC04AFL2 is 15 ns, with a guaranteed maximum of 19 ns over temperature (–55 °C to +125 °C) and voltage (2.0–6.0 V). This value is measured under standard AC test conditions (CL = 50 pF, input tr/tf = 6 ns) and applies uniformly across all six inverters in the MC74HC04AFL2 device.
Can unused inputs on the MC74HC04AFL2 be left floating?
No, unused inputs on the MC74HC04AFL2 must never be left floating. The datasheet explicitly states: "Unused inputs must always be tied to an appropriate logic voltage level (e.g., either GND or VCC)." Floating CMOS inputs can drift into the linear region, causing excessive supply current, localized heating, and unpredictable output behavior - potentially compromising reliability and EMC performance in the final system.
