Product details
Overview
MC74HC04AFEL from onsemi is a high-performance silicon-gate CMOS hex inverter IC containing six independent three-stage inverters in a 14-pin TSSOP package. It operates from 2.0 V to 6.0 V, delivers 10 LSTTL load drive capability, and exhibits 13 ns typical propagation delay at VCC = 6.0 V - enabling reliable signal inversion in digital logic interfaces, clock buffering, and waveform shaping circuits.
For engineers reviewing the MC74HC04AFEL datasheet, pinout, applications, or equivalent options, key selection considerations include its wide supply voltage range (2.0–6.0 V), guaranteed 10 LSTTL fanout, low input current (±0.1 µA), JEDEC Std. 7A compliance, and compatibility with both CMOS and LSTTL inputs when used with pullup resistors.
Technical Context
The MC74HC04AFEL implements six identical, non-inverting buffer stages configured as true inverters (Y = A̅) with three-stage CMOS topology for improved noise immunity and balanced rise/fall times. Each inverter features rail-to-rail output swing and symmetrical input thresholds defined by VCC-dependent VIH/VIL limits.
Its design supports mixed-voltage system interfacing: inputs accept standard CMOS logic levels and - with external pullups - tolerate LSTTL outputs; outputs directly drive CMOS, NMOS, and TTL loads without level-shifting circuitry. The device meets JEDEC Std. 7A and is Pb-free, halogen-free, and RoHS compliant.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.0 V to 6.0 V - enables operation across battery-powered, 3.3 V, and 5 V logic systems without voltage translation. |
| Propagation Delay (tPLH/tPHL) | 13 ns max at VCC = 6.0 V - ensures timing-critical signal inversion with predictable latency in high-speed digital paths. |
| Output Drive Capability | 10 LSTTL loads - provides sufficient current sourcing/sinking (±4.0 mA at VCC = 4.5 V) to drive multiple downstream logic inputs. |
| Input Leakage Current | ±0.1 µA max at VCC = 6.0 V - minimizes power loss and prevents unintended logic state shifts in high-impedance or battery-sensitive designs. |
| Operating Temperature | −55 °C to +125 °C - supports deployment in industrial, automotive under-hood, and extended-environment applications. |
| Input Capacitance | 10 pF max - reduces capacitive loading on driving sources, preserving signal integrity and edge rate in fanout-heavy nodes. |
| Power Dissipation Cap. | 20 pF typical per inverter - allows accurate dynamic power estimation (PD = CPD × VCC² × f) for thermal budgeting. |
Pinout & Package
MC74HC04AFEL is housed in a 14-lead Thin Shrink Small Outline Package (TSSOP-14), case 948G, with 0.65 mm pitch, 5.0 mm × 4.4 mm body, and exposed pad optional. Pin 1 is marked by a dot or beveled corner; the package is RoHS-compliant and Pb-free.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 3, 5, 9, 11, 13 | Inverter Input (A1–A6) | CMOS-compatible digital inputs accepting 0–VCC logic levels; require tie-high/tie-low if unused per datasheet Note 3. |
| 2, 4, 6, 8, 10, 12 | Inverter Output (Y1–Y6) | Full-swing CMOS outputs capable of sourcing/sinking ≥4.0 mA; electrically isolated per channel. |
| 7 | GND | Ground reference for all internal circuitry and I/O; must be low-impedance connection to minimize noise coupling. |
| 14 | VCC | Positive supply rail (2.0–6.0 V); requires local 0.1 µF decoupling capacitor near pin for stable operation. |
Key Features
| Feature | Design Value |
|---|---|
| Three-stage inverter architecture | Improves noise margin and stabilizes switching thresholds across temperature and voltage variations. |
| JEDEC Std. 7A compliance | Ensures interoperability with industry-standard logic families and guarantees electrical interface robustness. |
| High noise immunity | CMOS input structure rejects >40% VCC noise on inputs, reducing susceptibility to EMI in noisy environments. |
| Chip complexity: 36 FETs | Enables compact die size and low static power (ICC ≤ 1.0 µA at VCC = 6.0 V, −55°C to 25°C). |
| Pb-free, halogen-free, RoHS | Meets global environmental regulations and supports lead-free reflow soldering profiles (MSL Level 1). |

Equivalent & Alternatives
The following parts are listed as comparable options for similar hex inverter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74HC04DR | Same logic function and pinout; TI part rated for −40°C to +85°C only (vs. −55°C to +125°C for MC74HC04AFEL). | Not qualified for extended-temperature industrial or automotive under-hood use. | Select MC74HC04AFEL when full military-grade temperature range or AEC-Q100 qualification is required. |
| 74HC04PW,118 | NXP variant in TSSOP-14; identical DC/AC specs but different MSL rating (Level 3 vs. Level 1) and no AEC-Q100 option. | Limited moisture sensitivity handling; not recommended for high-reliability reflow or long-term storage without dry pack. | Prefer MC74HC04AFEL for production lines requiring zero bake-out and guaranteed MSL Level 1 handling. |
Compared with SN74HC04DR and 74HC04PW,118, the MC74HC04AFEL offers broader operating temperature support, superior moisture resilience, and automotive-grade qualification - making it the preferred choice for mission-critical industrial control, automotive subsystems, and aerospace-adjacent designs where long-term reliability is non-negotiable.

FAQ
What is the maximum operating temperature for MC74HC04AFEL?
The MC74HC04AFEL is rated for operation from −55 °C to +125 °C, verified across all electrical parameters in the datasheet's Recommended Operating Conditions table. This extended range supports deployment in under-hood automotive, industrial motor drives, and outdoor equipment where ambient temperatures exceed commercial-grade limits. The MC74HC04AFEL maintains guaranteed VIH/VIL, propagation delay, and output drive performance across this full span.
Does MC74HC04AFEL support 3.3 V logic systems?
Yes, MC74HC04AFEL fully supports 3.3 V operation: its supply range (2.0–6.0 V) includes 3.3 V, and its input thresholds scale with VCC (VIH = 2.1 V min, VIL = 0.9 V max at VCC = 3.0 V). Outputs swing rail-to-rail, ensuring compatible 0/3.3 V logic levels. The MC74HC04AFEL also tolerates 5 V-tolerant inputs when used with pullup resistors, enabling mixed-voltage interconnects.
Is MC74HC04AFEL pin-compatible with older TTL inverters?
Yes, MC74HC04AFEL is pinout-identical to the 74LS04 and MC14069, as confirmed in the datasheet's first paragraph. All six inverter inputs (pins 1,3,5,9,11,13) and outputs (pins 2,4,6,8,10,12) map directly, with VCC (pin 14) and GND (pin 7) in standard positions. This allows drop-in replacement in legacy LS-based PCBs - provided supply voltage and loading conditions align with HC specifications.
What is the input capacitance of MC74HC04AFEL?
The MC74HC04AFEL has a maximum input capacitance (Cin) of 10 pF per input, specified in both AC Characteristics tables for HC and HCT variants. This low value minimizes loading on upstream drivers - critical when fanout exceeds one or when driving long traces - and helps preserve signal edge rates in high-frequency digital paths. The MC74HC04AFEL's Cin remains stable across temperature and voltage, supporting predictable timing analysis.
Can MC74HC04AFEL drive LED indicators directly?
No, MC74HC04AFEL is not intended for direct LED driving. Its output current rating is ±4.0 mA (min) at VCC = 4.5 V - insufficient for typical indicator LEDs requiring 5–20 mA. Driving LEDs directly risks violating absolute maximum ratings (IOUT = ±25 mA per pin) and degrading long-term reliability. For LED interfacing, use MC74HC04AFEL to control a discrete transistor or dedicated LED driver IC instead.
