Product details
Overview
MC74ACT04DR2 from onsemi is a hex inverter IC in the 74ACT logic family, implementing six independent CMOS inverters with TTL-compatible inputs, 5.0 V nominal supply operation, ±24 mA output drive, and propagation delay as low as 1.5 ns (typ) at 5.0 V/50 pF - used for signal inversion and level translation in digital control and interface circuits.
For engineers reviewing the MC74ACT04DR2 datasheet, pinout, applications, or equivalent options, this page delivers verified electrical specs, SOIC-14 package details, real-world use cases, and validated alternative parts for industrial control, test equipment, and legacy TTL interface designs.
Technical Context
The MC74ACT04DR2 uses high-performance silicon-gate CMOS technology to deliver TTL-compatible input thresholds (VIH = 2.0 V min, VIL = 0.8 V max at VCC = 4.5–5.5 V) while maintaining CMOS-level power efficiency and noise immunity. It operates across −40 °C to +85 °C with guaranteed 5.0 V ±0.5 V supply compliance.
All six inverters are fully buffered, with symmetrical output drive (IOH = −24 mA, IOL = 24 mA), low dynamic output current capability (±75 mA peak), and input capacitance of 4.5 pF - enabling clean edge integrity in high-speed bus driving and clock buffering applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Family | 74ACT - TTL-compatible CMOS with 5 V operation and fast switching |
| Supply Voltage Range | 4.5 V to 5.5 V - ensures compatibility with standard 5 V TTL and mixed-voltage systems |
| Propagation Delay | 1.5 ns (typ), 9.0 ns (max) at 5.0 V/50 pF - supports >100 MHz toggle rates in clean digital paths |
| Output Drive | ±24 mA - sufficient to directly drive multiple 74-series TTL loads or small capacitive buses |
| Input Thresholds | VIH = 2.0 V min, VIL = 0.8 V max - enables reliable interfacing with legacy 5 V TTL outputs |
| Quiescent ICC | 4.0 µA (typ), 40 µA (max) - ultra-low static power for always-on logic stages |
| ESD Rating | HBM > 2000 V - robust handling in manual assembly and board-level integration |
Pinout & Package
MC74ACT04DR2 is housed in a Pb-free SOIC-14 (Case 751A) package, 8.75 mm × 3.90 mm body, 1.27 mm pitch, with gull-wing leads suitable for reflow soldering per JEDEC J-STD-020.

Equivalent & Alternatives
The following parts are listed as comparable options for similar hex inverter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74ACT04DR | Identical logic function, same SOIC-14 package, TI-specified VIH/VIL thresholds (2.0 V/0.8 V), but rated for −40 °C to +125 °C operating range | Preferred for automotive under-hood or extended-temperature industrial environments | Select SN74ACT04DR when ambient temperature exceeds +85 °C or AEC-Q100 qualification is required |
| MC74AC04DR2G | Same SOIC-14 package and pinout, but AC-family - CMOS-only inputs (VIH = 3.15 V min at 4.5 V), slower propagation (7.0 ns max), lower drive (±24 mA same) | Suitable only for pure CMOS systems or where TTL compatibility is unnecessary | Choose MC74AC04DR2G only if interfacing exclusively with CMOS sources and lower speed suffices |
Compared with MC74ACT04DR2, SN74ACT04DR offers wider temperature range but identical pinout and logic behavior, while MC74AC04DR2G lacks TTL compatibility and trades speed for slightly lower power - making MC74ACT04DR2 optimal for mixed-logic 5 V systems needing reliability and interoperability.

FAQ
What is the maximum operating temperature for MC74ACT04DR2?
The MC74ACT04DR2 is rated for an operating ambient temperature range of −40 °C to +85 °C. This specification is guaranteed per the Recommended Operating Conditions table in the official onsemi datasheet. Exceeding +85 °C may degrade parametric performance or reliability. Derating guidelines apply above 70 °C for sustained operation.
Is MC74ACT04DR2 pin-compatible with older 74LS04 or 74F04 devices?
Yes - MC74ACT04DR2 uses the standard SOIC-14 footprint and identical 14-pin assignment as 74LS04 and 74F04. All six inverter inputs and outputs align directly, and GND (pin 7) and VCC (pin 14) match. No PCB modification is needed for drop-in replacement in existing 5 V designs.
Does MC74ACT04DR2 require external pull-up resistors on its inputs?
No - MC74ACT04DR2 has TTL-compatible inputs with defined VIH (≥2.0 V) and VIL (≤0.8 V) thresholds at 5 V supply, so it accepts standard 5 V logic levels without pull-ups. Its input leakage current is ≤±1.0 µA, eliminating need for biasing unless floating inputs are present in the system design.
What is the typical power dissipation of MC74ACT04DR2 at 5 V and 10 MHz toggle rate?
At 5 V supply and 10 MHz toggle frequency with 50 pF load per output, MC74ACT04DR2 dissipates approximately 15 mW typical - calculated using CPD = 30 pF and formula P = CPD × VCC² × f. Quiescent ICC is only 4.0 µA, so dynamic switching dominates total consumption in active use.
Can MC74ACT04DR2 drive a 50 Ω transmission line directly?
No - MC74ACT04DR2 is not designed as a line driver. Its 24 mA output drive and CMOS output structure lack controlled impedance or slew-rate limiting required for clean 50 Ω termination. For such applications, use dedicated line drivers (e.g., SN65LVDS1) or add series termination. MC74ACT04DR2 is intended for board-level logic interfacing, not cable driving.
