Product details
Overview
MC74AC04MR1 from ON Semiconductor is a hex inverter logic IC in EIAJ-14 package, delivering 24 mA output drive per channel at 5 V supply, with propagation delay as low as 4.0 ns (typ) and TTL-compatible input thresholds only on ACT variants - this part is AC-series, optimized for high-speed digital signal inversion in clock distribution, bus buffering, and level translation circuits.
For engineers reviewing the MC74AC04MR1 datasheet, pinout, applications, or equivalent options, key selection criteria include guaranteed 24 mA sink/source capability, 5.0 V ±0.5 V operating range, −40°C to +85°C industrial temperature rating, and EIAJ-14 footprint compatibility with SOIC-14 and TSSOP-14 alternatives where board space or thermal performance differs.
Technical Context
The MC74AC04MR1 implements six independent CMOS inverters in a single monolithic die, using advanced AC logic process technology to achieve balanced rise/fall times and low dynamic power dissipation. It operates without internal hysteresis or Schmitt-trigger inputs, distinguishing it from noise-immune variants.
Its input voltage thresholds are CMOS-ratioed (VIH = 2.1 V min at VCC = 3.0 V; VIL = 0.9 V max), not TTL-compatible - that specification applies exclusively to the MC74ACT04 family. Output drive strength is symmetric (±24 mA), with VOH ≥ 2.9 V and VOL ≤ 0.44 V under full load at 5.5 V VCC.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Function | Hex inverter (6 independent NOT gates) |
| Supply Voltage Range | 2.0 V to 6.0 V - supports mixed-voltage system interfacing and battery-backed operation down to 2 V |
| Output Drive (IOL/IOH) | ±24 mA per output - sufficient to directly drive LEDs, small capacitive loads (≤50 pF), or fan-out of 10+ 74AC inputs |
| Propagation Delay (tPLH/tPHL) | 4.0 ns typ at VCC = 5.0 V, CL = 50 pF - enables reliable operation in >100 MHz clock domains with margin |
| Input Thresholds (VIH/VIL) | VIH = 2.1 V min, VIL = 0.9 V max at VCC = 3.0 V - ensures robust noise immunity in 3.3 V systems |
| Quiescent ICC | 40 μA max at VCC = 5.5 V - enables low-static-power operation in always-on control logic |
| Operating Temperature | −40°C to +85°C - qualified for industrial-grade embedded controllers and motor drives |
Pinout & Package
EIAJ-14 (Case 965) package: 14-pin plastic surface-mount with 0.65 mm lead pitch, 10.2 mm × 5.3 mm body size, and gull-wing leads - compatible with standard SOIC-14 reflow profiles but with narrower width than SOIC.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 3, 5, 9, 11, 13 | Input (A1–A6) | CMOS-compatible digital inputs; no internal pull-up/down; require defined logic levels |
| 2, 4, 6, 8, 10, 12 | Output (Y1–Y6) | Inverted logic outputs; capable of sourcing/sinking 24 mA continuously |
| 7 | GND | Ground reference for all inputs, outputs, and internal circuitry; must be low-impedance |
| 14 | VCC | Positive supply rail; bypass capacitor (0.1 μF ceramic) required within 5 mm of pin for stable switching |
Key Features
| Feature | Design Value |
|---|---|
| High-Speed AC Logic | 4.0 ns typical propagation delay at 5 V enables use in fast control loops and timing-critical signal conditioning |
| Wide Supply Range | 2.0–6.0 V operation allows direct interface with 3.3 V microcontrollers and 5 V legacy peripherals without level shifters |
| Strong Output Drive | 24 mA per output eliminates need for external buffer stages when driving moderate capacitive or resistive loads |
| Low Input Current | ±1.0 μA max input leakage ensures minimal loading on upstream drivers and preserves signal integrity in high-fanout nets |
| Pb-Free Construction | RoHS-compliant materials and terminations meet IPC/JEDEC J-STD-020 moisture sensitivity Level 3 (MSL3) |
Applications
| Industrial PLC I/O Conditioning | Digital Audio Clock Buffering |

Equivalent & Alternatives
The following parts are listed as comparable options for similar hex inverter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MC74AC04DR2 | SOIC-14 package (Case 751A); same electrical specs; 2500-piece tape-and-reel | Better thermal dissipation and hand-solderability; larger PCB footprint than EIAJ-14 | Select when manual assembly, higher power cycling, or legacy SOIC layout reuse is required. |
| SN74AC04PWR | TSSOP-14 package (Texas Instruments); identical AC logic specs; 2000-piece tape-and-reel | Narrower body (4.4 mm vs. 5.3 mm), finer 0.65 mm pitch; slightly lower thermal resistance | Select when board space is constrained and TI supply chain alignment is preferred. |
Compared with MC74AC04MR1, the SOIC-14 variant offers easier prototyping and higher thermal mass, while the TSSOP-14 provides superior density and automated placement yield - both retain identical timing, drive, and voltage specifications, making them functionally interchangeable where package constraints allow.

FAQ
What is the maximum operating supply voltage for MC74AC04MR1?
The MC74AC04MR1 supports a DC supply voltage range of −0.5 V to +7.0 V, but its recommended operating range is 2.0 V to 6.0 V. Operation above 6.0 V risks exceeding absolute maximum ratings and may cause irreversible damage. For sustained reliability, keep VCC ≤ 6.0 V in all designs using MC74AC04MR1.
Does MC74AC04MR1 have TTL-compatible inputs?
No, MC74AC04MR1 does not have TTL-compatible inputs. Its input thresholds follow CMOS ratios (VIH = 2.1 V min at VCC = 3.0 V). The TTL-compatible version is the MC74ACT04 series. Using MC74AC04MR1 with 5 V TTL outputs requires verifying that the TTL VOH exceeds the MC74AC04MR1's VIH minimum under worst-case conditions.
What is the pin 1 marking convention for MC74AC04MR1 in EIAJ-14 package?
On the MC74AC04MR1 in EIAJ-14 (Case 965) package, pin 1 is identified by a small circular indentation or laser-marked dot located near the top-left corner of the package body when the marking side faces up and the leads point downward. This matches JEDEC-standard orientation for EIAJ packages and aligns with the pin 1 indicator shown in Figure 1 of the ON Semiconductor datasheet for MC74AC04MR1.
Can MC74AC04MR1 drive a 50 pF capacitive load at 10 MHz?
Yes, MC74AC04MR1 can reliably drive a 50 pF load at 10 MHz. Its AC characteristics specify tPLH/tPHL ≤ 7.5 ns (max) at CL = 50 pF and VCC = 5.0 V, supporting signal periods down to ~100 ns - well below the 100 ns period of a 10 MHz square wave. Rise/fall times remain monotonic with no overshoot under these conditions when properly decoupled.
Is MC74AC04MR1 RoHS compliant and lead-free?
Yes, MC74AC04MR1 is manufactured in a Pb-free (lead-free) package per ON Semiconductor's compliance documentation. It meets RoHS Directive 2011/65/EU and is rated MSL3 per J-STD-020. The "R1" suffix in MC74AC04MR1 denotes the EIAJ-14 Pb-free variant, and its marking includes "AC04" without lead-based identifiers - confirming full RoHS conformance for MC74AC04MR1.
