Product details
Overview
MC74AC04N from onsemi is a high-performance silicon-gate CMOS hex inverter IC operating across 2.0–6.0 V supply, delivering ±24 mA output drive per channel with propagation delays as low as 4.0 ns (VCC = 5.0 V, CL = 50 pF), used for digital signal inversion and waveform shaping in logic interface circuits.
For engineers reviewing the MC74AC04N datasheet, pinout, applications, or equivalent options, key selection criteria include supply voltage range compatibility (2.0–6.0 V), TTL-compatible input thresholds (not applicable - AC variant only), SOIC-14 package footprint, and guaranteed ±24 mA output drive at 5.0 V.
Technical Context
The MC74AC04N implements six independent CMOS inverter gates in a single monolithic die, each with rail-to-rail output swing and symmetrical rise/fall times under matched load conditions. It uses standard CMOS input structure - not TTL-compatible - distinguishing it from the MC74ACT04 variant.
Designed for general-purpose logic-level translation and signal conditioning, it supports operation from −40 °C to +85 °C ambient, exhibits <4.5 ns typical tPLH/tPHL at 5.0 V/50 pF, and maintains VIH/VIL thresholds referenced to VCC (e.g., VIH = 2.1 V min at VCC = 3.0 V).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.0 V to 6.0 V - supports mixed-voltage system interfacing and battery-powered 3.3 V/5.0 V logic domains |
| Output Drive Current | ±24 mA per inverter - sufficient to directly drive multiple 74-series TTL inputs or small capacitive loads (<50 pF) |
| Propagation Delay | 7.0 ns max (VCC = 5.0 V, CL = 50 pF) - enables reliable operation in ≤70 MHz clock distribution or data path inversion |
| Input Thresholds | VIH = 2.1 V min @ VCC = 3.0 V; VIL = 0.9 V max - ensures noise margin >0.4 V under nominal 3.3 V operation |
| Quiescent ICC | 40 μA max @ VCC = 5.5 V - enables low-static-power use in always-on control logic stages |
| ESD Rating | >2000 V HBM - provides robust handling during board assembly and field service without external protection |
Pinout & Package

Equivalent & Alternatives
The following parts are listed as comparable options for similar hex inverter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74AC04N | Same AC logic family, identical electrical specs and SOIC-14 pinout; manufactured by Texas Instruments | No functional difference; validated for same industrial and embedded use cases | Select SN74AC04N if TI supply chain alignment or dual-sourcing strategy is required |
| MC74HC04N | Higher propagation delay (19 ns max @ 4.5 V), lower output drive (±4 mA), and narrower VCC range (2.0–6.0 V same, but weaker drive at low VCC) | Better suited for ultra-low-power systems where speed <10 MHz and drive <10 mA suffice | Choose MC74HC04N only when power budget is tighter than performance requirements - not a drop-in replacement for high-drive needs |
Compared with MC74AC04N, SN74AC04N offers identical timing, drive, and pinout with alternate sourcing, while MC74HC04N trades speed and current capability for reduced static power - making it suitable only in non-critical, low-frequency applications.

FAQ
What is the maximum operating supply voltage for MC74AC04N?
The MC74AC04N supports a DC supply voltage range of 0.5 V to +6.5 V absolute maximum, with recommended operation from 2.0 V to 6.0 V. At 6.0 V, it delivers full ±24 mA output drive and maintains VOH ≥ 5.4 V and VOL ≤ 0.44 V under load - enabling interoperability with both 3.3 V and 5.0 V logic families. Exceeding 6.5 V risks permanent damage.
Does MC74AC04N have TTL-compatible inputs?
No, MC74AC04N does not have TTL-compatible inputs. Its input thresholds scale with VCC (e.g., VIH = 2.1 V min at VCC = 3.0 V), unlike the MC74ACT04 variant which specifies fixed 2.0 V VIH and 0.8 V VIL for TTL compatibility. Using MC74AC04N with TTL outputs may result in marginal noise margins below VCC = 4.5 V.
What is the propagation delay of MC74AC04N at 3.3 V supply?
At VCC = 3.3 V and CL = 50 pF, the MC74AC04N has a maximum propagation delay of 9.0 ns (tPLH/tPHL). Typical delay is 4.5 ns. This value is confirmed in the AC Characteristics table on page 3 of the official datasheet (Rev. 10, January 2024), and reflects worst-case performance across temperature and process variation.
Can MC74AC04N drive a 50 pF capacitive load reliably?
Yes, MC74AC04N is fully characterized for 50 pF capacitive loads - all AC specifications (including tPLH, tPHL, and output rise/fall times) are measured at CL = 50 pF. With its ±24 mA drive strength and sub-7 ns delay at 5.0 V, it maintains signal integrity and timing margins for standard PCB traces and small bus stubs without external termination.
Is MC74AC04N pin-compatible with 74LS04?
Yes, MC74AC04N uses the standard 14-pin SOIC package with identical pinout to 74LS04: Pin 1 (1A), Pin 2 (1Y), ..., Pin 7 (GND), Pin 8 (4A), ..., Pin 14 (VCC). However, MC74AC04N draws significantly less quiescent current (40 μA vs. ~10 mA) and delivers faster switching - making it a functional and physical replacement, though input threshold behavior differs due to CMOS vs. TTL architecture.
