Product details
Overview
MM74HCT04M from ON Semiconductor is a hex inverter IC fabricated in advanced silicon-gate CMOS technology, providing TTL/LS pin-out and threshold compatibility, 12 ns typical propagation delay (tPLH/tPHL), ±25 mA output drive capability, and operation across 4.5–5.5 V supply with –40°C to +85°C temperature range. It serves as a logic-level signal inverter in digital control, interface buffering, and clock conditioning circuits.
For engineers reviewing the MM74HCT04M datasheet, pinout, applications, or equivalent options, key selection considerations include its LS-TTL plug-in replacement capability, triple-buffered output stage for noise immunity, guaranteed 4.0 mA HIGH/LOW drive at VCC = 4.5 V, and JEDEC MS-012 SOIC-14 package compatibility.
Technical Context
The MM74HCT04M implements six independent inverting buffers using CMOS circuitry with input clamp diodes to VCC and GND for ESD protection. Its input thresholds (VIH = 2.0 V min, VIL = 0.8 V max) match LS-TTL logic families, enabling direct interfacing without level-shifting.
All six channels feature identical DC and AC characteristics: guaranteed VOH ≥ 3.98 V and VOL ≤ 0.26 V at 4.0 mA load, tPLH/tPHL ≤ 20 ns over full temperature range, and CPD = 20 pF for dynamic power estimation. The device operates with no internal feedback or enable logic-pure combinational inversion.

Equivalent & Alternatives
The following parts are listed as comparable options for similar hex inverter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74HCT04DR | Same logic function, identical AC/DC specs, but TI's SOIC-14 uses JEDEC MO-153 footprint (4.4 mm width vs. MM74HCT04M's 3.9 mm) | Requires PCB land pattern revision; not mechanically interchangeable | Select when sourcing from TI-authorized channels or when MO-153 footprint is already standardized |
| 74VHC04M | Higher speed (tPD ≤ 7.5 ns typ), wider VCC range (2–5.5 V), but VIH/VIL thresholds differ (VIH = 3.5 V min at VCC = 4.5 V) | Not TTL-compatible; requires upstream logic redesign for proper high-level recognition | Select only for new designs targeting ultra-low power or dual-supply flexibility-not for LS-TTL drop-in replacement |
Compared with SN74HCT04DR and 74VHC04M, the MM74HCT04M uniquely delivers verified LS-TTL pin-and-function compatibility in JEDEC MS-012 SOIC-14, making it the only choice for zero-layout-change upgrades of legacy 74LS04-based systems requiring industrial temperature support and proven long-term availability.

FAQ
What is the maximum output current per pin for MM74HCT04M?
The MM74HCT04M guarantees ±4.0 mA output drive at VCC = 4.5 V and ±4.8 mA at VCC = 5.5 V under specified load conditions. Absolute maximum DC output current per pin is ±25 mA, but sustained operation above ±4.0 mA may exceed thermal limits in SOIC packaging without heatsinking or airflow.
Is MM74HCT04M compatible with 74LS04 in existing PCB layouts?
Yes, MM74HCT04M uses the same JEDEC MS-012 SOIC-14 footprint as 74LS04, with identical pinout, mechanical dimensions, and solder pad requirements. No PCB modification is needed for substitution, and its VIH/VIL thresholds ensure functional equivalence in LS-TTL signal environments.
Does MM74HCT04M require external pull-up resistors on inputs?
No, MM74HCT04M inputs are CMOS-based with high impedance and built-in clamp diodes, so external pull-ups are unnecessary unless specific logic states must be enforced during power-up or reset. Unused inputs should be tied to VCC or GND to prevent floating nodes and unintended switching.
What is the power dissipation of MM74HCT04M at 5 MHz operation?
At 5 MHz with CL = 15 pF and VCC = 5.0 V, MM74HCT04M dissipates approximately 3.7 mW (typical), calculated using CPD = 20 pF and the formula PD = CPD × VCC² × f + ICC × VCC. Quiescent ICC contributes <0.1 mW, making dynamic capacitance the dominant factor.
Can MM74HCT04M operate at 3.3 V supply voltage?
No, MM74HCT04M is not characterized or guaranteed for operation below 4.5 V. Its input thresholds (VIH = 2.0 V min) and output drive specifications assume VCC ≥ 4.5 V. For 3.3 V systems, consider 74LVC04 or 74AHC04 variants instead.
