Product details
Overview
MC74AC04ML1 from onsemi is a hex inverter logic IC in EIAJ-14 package, featuring TTL-compatible inputs (for ′ACT variants), 24 mA output drive capability, propagation delays as low as 4.0 ns at 5.0 V, and operation across –40°C to +85°C ambient temperature - used for signal inversion and waveform shaping in digital control interfaces.
For engineers reviewing the MC74AC04ML1 datasheet, pinout, applications, or equivalent options, key selection criteria include supply voltage range (2.0–6.0 V for AC, 4.5–5.5 V for ACT), input threshold compatibility, output current capability (±24 mA), and EIAJ-14 footprint constraints in space-constrained PCB layouts.
Technical Context
The MC74AC04ML1 implements six independent CMOS inverters in a single monolithic IC, with rail-to-rail output swing and Schmitt-trigger–free inputs. It operates under two logic families: 74AC (CMOS-level inputs, 2.0–6.0 V VCC) and 74ACT (TTL-level inputs, 4.5–5.5 V VCC), though the ML1 suffix corresponds specifically to the 74AC variant in EIAJ-14 package.
Its design supports high-speed digital interfacing with guaranteed tPLH/tPHL ≤ 7.5 ns (VCC = 5.0 V, CL = 50 pF) and low quiescent ICC ≤ 40 µA. Input leakage remains ≤ ±1.0 µA over full temperature range, enabling reliable noise margin in mixed-signal environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Family | 74AC - CMOS-compatible inputs, 2.0–6.0 V supply operation |
| Output Drive | ±24 mA - sufficient to directly drive LEDs, small MOSFET gates, or multiple 74-series inputs |
| Propagation Delay | ≤ 7.5 ns @ 5.0 V - enables use in sub-100 MHz clock distribution and data path inversion |
| Input Thresholds | VIH = 2.1 V, VIL = 0.9 V @ VCC = 3.0 V - ensures robust noise immunity in 3.3 V systems |
| Operating Temp | –40°C to +85°C - qualified for industrial-grade embedded control and instrumentation |
| Power Dissipation Cap | CPD = 30 pF - allows accurate dynamic power estimation in high-frequency toggle scenarios |
Pinout & Package
EIAJ-14 (Case 965) surface-mount package, 14-pin, 0.3 mm lead pitch, body size 5.0 × 6.2 mm - compatible with standard reflow profiles and automated placement.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 3, 5, 9, 11, 13 | Input (A1–A6) | CMOS-compatible digital input per inverter stage; no internal pull-up/down |
| 2, 4, 6, 10, 12, 14 | Output (Y1–Y6) | Inverted logic output; capable of sourcing/sinking 24 mA continuously |
| 7 | GND | Ground reference for all inputs, outputs, and internal circuitry |
| 14 | VCC | Positive supply rail (2.0–6.0 V); decoupling capacitor required near pin |
Key Features
| Feature | Design Value |
|---|---|
| High-Speed Inversion | Propagation delay ≤ 7.5 ns at 5.0 V enables clean edge regeneration in timing-critical paths |
| Wide Supply Range | 2.0–6.0 V operation supports interoperability across 3.3 V and 5 V logic domains without level shifters |
| Low Power Consumption | ICC ≤ 40 µA at 5.5 V ensures minimal static power draw in battery-backed or always-on subsystems |
| Robust Input Noise Margin | VIH/VIL thresholds maintain ≥ 0.8 V DC noise immunity at VCC = 3.0 V, reducing false triggering |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar hex inverter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74AC04N | PDIP-14 package; identical AC electrical specs but larger footprint and higher thermal resistance | Suitable for prototyping or through-hole production; not drop-in for surface-mount EIAJ-14 layouts | Select when manual assembly, socketing, or thermal testing with heatsink clips is required |
| 74LVC04PW | Lower VCC range (1.65–3.6 V); 24 mA drive only up to 3.3 V; smaller TSSOP-14 package | Optimized for modern low-voltage MCU interfaces; incompatible with 5 V systems | Prefer for 3.3 V-only designs where board space is critical and 5 V tolerance is unnecessary |
Compared with SN74AC04N and 74LVC04PW, the MC74AC04ML1 uniquely balances 5 V system compatibility, EIAJ-14 surface-mount efficiency, and industrial temperature support - making it optimal for volume-manufactured industrial controls requiring long-term supply stability and mixed-voltage interoperability.

FAQ
What logic family does the MC74AC04ML1 belong to, and what supply voltages does it support?
The MC74AC04ML1 belongs to the 74AC logic family and supports a supply voltage range of 2.0 V to 6.0 V. This allows interoperability with both 3.3 V and 5 V digital systems without level-shifting circuitry. Its input thresholds scale with VCC, ensuring consistent noise margins across the operating range. The MC74AC04ML1 is not TTL-input compatible - that functionality applies only to the ′ACT variant (e.g., MC74ACT04).
Does the MC74AC04ML1 have Schmitt-trigger inputs?
No, the MC74AC04ML1 does not feature Schmitt-trigger inputs. Its inputs are standard CMOS with symmetric VIH/VIL thresholds referenced to VCC. This means it requires clean, monotonic input transitions to avoid metastability or oscillation on slow-rising signals. For noisy or slowly varying inputs, an external RC filter or dedicated Schmitt-trigger device (e.g., MC74HC14) should be used upstream of the MC74AC04ML1.
What is the maximum output current per pin for the MC74AC04ML1, and how is it specified?
The MC74AC04ML1 guarantees ±24 mA output current per inverter output (IOL = +24 mA, IOH = –24 mA) under recommended operating conditions. This rating is specified at VCC = 3.0 V, 4.5 V, and 5.5 V with VOH ≥ 2.9 V and VOL ≤ 0.44 V. Exceeding this current may cause output voltage degradation or thermal stress; simultaneous switching of all six outputs should consider total package power dissipation limits.
Is the MC74AC04ML1 pin-compatible with other 74AC hex inverters in different packages?
Yes, the MC74AC04ML1 shares identical pinout and logic function with all 74AC04 variants (e.g., MC74AC04D, MC74AC04N, MC74AC04DT) across SOIC-14, PDIP-14, TSSOP-14, and EIAJ-14 packages. Pin 1 is input A1, pin 2 is output Y1, and so on - matching the industry-standard 14-lead hex inverter configuration. However, physical mounting and thermal performance differ significantly between packages.
What is the typical propagation delay of the MC74AC04ML1, and under what conditions is it measured?
The typical propagation delay of the MC74AC04ML1 is 4.0 ns at VCC = 5.0 V with CL = 50 pF load, measured from 50% input transition to 50% output transition. The maximum guaranteed delay is 7.5 ns under the same conditions. These values apply to both tPLH and tPHL, confirming symmetrical rise/fall performance critical for clock and data path integrity in high-speed digital designs using the MC74AC04ML1.
