Product details
Overview
MC74ACT04D from onsemi is a hex inverter IC in the 74ACT logic family, implementing six independent CMOS inverting buffers with TTL-compatible inputs. It operates at 4.5 V to 5.5 V supply, delivers ±24 mA output drive, and achieves typical propagation delay of 8.5 ns at 5 V/50 pF. It is used in digital signal inversion, level translation, and clock buffering in industrial control and embedded interface circuits.
For engineers reviewing the MC74ACT04D datasheet, pinout, applications, or equivalent options, key selection considerations include its TTL-compatible input thresholds (VIH = 2.0 V, VIL = 0.8 V at VCC = 5 V), rail-to-rail output swing, SOIC-14 Pb-free package, and guaranteed operation from −40 °C to +85 °C ambient.
Technical Context
The MC74ACT04D uses high-performance silicon-gate CMOS technology to deliver TTL-compatible input logic levels while maintaining CMOS power efficiency. Its input structure accepts standard TTL voltage thresholds (VIH ≥ 2.0 V, VIL ≤ 0.8 V), enabling direct interfacing with legacy 5 V TTL systems without level shifters.
All six inverters are fully buffered with symmetrical output drive capability: IOH = −24 mA and IOL = 24 mA at VCC = 5 V, supporting fan-out to multiple LS-TTL loads. Propagation delays are tightly specified (tPLH/tPHL ≤ 9.0 ns max at 5 V/50 pF) and characterized across the full industrial temperature range.

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 family, identical DC/AC specs, TI-branded SOIC-14 package | No functional difference; validated for same industrial temperature range | Direct second-source option with identical pinout and performance |
| MC74VHC04DT | VHC family: lower drive (±8 mA), wider supply (2–5.5 V), faster max speed but no TTL input compatibility | Requires input voltage scaling if interfacing with TTL; unsuitable for direct 74LS04 replacement | Select only when operating below 5 V or when lower power and wider VCC range outweigh drive/TTL needs |
Compared with SN74ACT04DR and MC74VHC04DT, the MC74ACT04D uniquely combines TTL-compatible inputs, ±24 mA drive, and industrial temperature rating in a single SOIC-14 package-making it optimal for legacy 5 V system upgrades where signal integrity and drop-in compatibility are critical.

FAQ
What is the supply voltage range for MC74ACT04D?
The MC74ACT04D operates over a supply voltage range of 4.5 V to 5.5 V. This narrow range ensures TTL-compatible input thresholds and stable output drive characteristics. Operation outside this range is not guaranteed per datasheet specifications, and extended exposure may affect reliability or cause undefined logic states. The MC74ACT04D is not rated for 3.3 V operation.
Does MC74ACT04D have TTL-compatible inputs?
Yes, the MC74ACT04D features TTL-compatible inputs: VIH is guaranteed ≥ 2.0 V and VIL ≤ 0.8 V at VCC = 5 V. This allows direct connection to standard TTL outputs (e.g., 74LS series) without external level-shifting circuitry. The MC74ACT04D maintains this compatibility across its full −40 °C to +85 °C operating range.
What is the maximum output drive capability of MC74ACT04D?
The MC74ACT04D provides ±24 mA output drive per inverter stage at VCC = 5 V - IOH = −24 mA (source) and IOL = 24 mA (sink). This enables driving up to 10 LS-TTL loads or moderate PCB trace capacitance. Exceeding these limits risks exceeding absolute maximum ratings and may degrade timing or cause latch-up.
Is MC74ACT04D available in a Pb-free package?
Yes, the MC74ACT04D is supplied in a Pb-free SOIC-14 package (Case 751A) compliant with RoHS Directive 2011/65/EU. The "G" suffix in ordering codes (e.g., MC74ACT04DR2G) explicitly denotes Pb-free construction. Lead-free reflow profiles per J-STD-020 apply, and the device supports standard IR reflow processes.
What is the propagation delay of MC74ACT04D at 5 V?
At VCC = 5.0 V and CL = 50 pF, the MC74ACT04D exhibits typical propagation delays of tPLH = 8.5 ns and tPHL = 8.0 ns, with maximum values of 9.0 ns and 8.5 ns respectively across −40 °C to +85 °C. These values are measured under standardized load conditions and define the upper timing bound for synchronous design margining.
