Product details
Overview
MC74ACT04DG from onsemi is a hex inverter IC with TTL-compatible inputs, designed for digital logic inversion in 5 V systems. It delivers ±24 mA output drive, supports −40 °C to +85 °C operation, and features SOIC-14 packaging with Pb-free construction. It is used in bus buffering, signal conditioning, and clock inversion circuits where noise immunity and rail-to-rail swing are required.
For engineers reviewing the MC74ACT04DG datasheet, pinout, applications, or equivalent options, this page provides verified functional specifications, package dimensions, real-world use cases, and validated alternative options for industrial control, automotive body electronics, and embedded interface design.
Technical Context
The MC74ACT04DG implements six independent CMOS inverters in a single SOIC-14 package, each with buffered outputs and TTL-compatible input thresholds (VIH = 2.0 V min, VIL = 0.8 V max at VCC = 4.5–5.5 V). Its propagation delay is 1.0–9.0 ns (tPLH/tPHL) under 50 pF load at 5 V, and it maintains stable DC output voltage levels (VOH ≥ 4.4 V, VOL ≤ 0.44 V) while sinking or sourcing up to 24 mA per channel.
It operates within a strict 4.5–5.5 V supply range, exhibits low input leakage (±1.0 µA), and integrates latch-up protection rated to 100 mA at 85 °C. The device meets JEDEC ESD standards (>2000 V HBM) and is qualified for industrial ambient conditions without derating.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 4.5 V to 5.5 V - Ensures compatibility with standard 5 V TTL/CMOS logic rails without level-shifting. |
| Output Drive | ±24 mA - Supports direct driving of multiple LS-TTL loads or moderate-capacitance PCB traces. |
| Propagation Delay | 1.0–9.0 ns - Enables reliable operation in high-speed digital control paths up to ~100 MHz toggle rate. |
| Input Thresholds | VIH ≥ 2.0 V, VIL ≤ 0.8 V - Guarantees robust noise margin when interfacing with legacy TTL outputs. |
| DC Output Levels | VOH ≥ 4.4 V, VOL ≤ 0.44 V @ 24 mA - Maintains valid logic '1'/'0' under full load, minimizing false switching. |
| Operating Temp | −40 °C to +85 °C - Qualified for under-hood automotive modules and industrial PLC I/O stages. |
| ESD Rating | >2000 V HBM - Reduces risk of field failure during handling and board-level assembly. |
Pinout & Package
MC74ACT04DG uses a 14-pin SOIC-14 (Case 751A) package with 1.27 mm pitch, 8.75 mm × 3.9 mm body, and 1.75 mm max height. Pin 1 is index-marked; pins 7 and 14 are GND and VCC respectively.

Equivalent & Alternatives
The following parts are listed as comparable options for similar hex inverter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74ACT04DR | Same logic function, identical AC/DC specs, TI-manufactured SOIC-14 package with same pinout. | No functional deviation; validated for identical 5 V industrial control use cases. | Select when dual-sourcing or TI-aligned BOMs are required. |
| 74VHC04M | Higher VCC range (2–5.5 V), lower drive (±8 mA), faster max speed (7 ns), but non-TTL input thresholds (VIH = 3.5 V). | Not suitable for direct TTL interfacing; requires redesign if driving legacy 74LS outputs. | Choose only for new 3.3/5 V mixed-rail designs where input compatibility is not constrained. |
Compared with SN74ACT04DR and 74VHC04M, the MC74ACT04DG uniquely combines guaranteed TTL input compatibility, ±24 mA drive, and industrial temperature qualification in a single Pb-free SOIC-14 package-making it optimal for drop-in replacement in legacy 5 V control systems.

FAQ
What is the supply voltage range for MC74ACT04DG?
The MC74ACT04DG operates strictly within 4.5 V to 5.5 V. Operation outside this range violates recommended conditions and may cause undefined logic states or accelerated wear. This narrow window ensures TTL input compatibility and stable output drive; it is not rated for 3.3 V or 2.5 V operation, unlike some VHC or LVC variants.
Does MC74ACT04DG have Schmitt-trigger inputs?
No, the MC74ACT04DG does not feature Schmitt-trigger inputs. Its input thresholds are fixed TTL-compatible levels (VIH ≥ 2.0 V, VIL ≤ 0.8 V at VCC = 5 V), with no hysteresis. For noisy signal environments requiring noise rejection, an external RC filter or dedicated Schmitt inverter like MC74VHC14 should be used instead of relying on MC74ACT04DG.
Can MC74ACT04DG drive LED indicators directly?
Yes, MC74ACT04DG can drive standard 5 V LEDs directly when configured as a low-side switch (LED anode to VCC, cathode to output). With 24 mA sink capability and VOL ≤ 0.44 V at that current, it supports up to ~20 mA LED current with appropriate series resistance-no external transistor is needed for indicator-class loads.
Is MC74ACT04DG pin-compatible with MC74AC04DG?
Yes, MC74ACT04DG is pin-compatible with MC74AC04DG: both use identical SOIC-14 pinouts and share the same six inverter topology. However, MC74AC04DG has CMOS-only inputs (VIH = 3.15 V min at 4.5 V), so substituting it for MC74ACT04DG in TTL-driven systems risks logic misreads unless input voltage levels are verified.
What is the maximum capacitive load MC74ACT04DG can drive reliably?
MC74ACT04DG is characterized for CL = 50 pF in its AC specifications, with propagation delay and output swing guaranteed under that load. While it can drive higher capacitance (e.g., >100 pF) with reduced edge rates, signal integrity degrades beyond 50 pF without series termination. For >100 pF routing, add a 22–47 Ω series resistor at the output to dampen reflections and preserve timing margins in the MC74ACT04DG circuit.
