Product details
Overview
MM74HCT04MTC 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, and operation across 4.5–5.5 V supply at –40°C to +85°C. It serves as a low-power, triple-buffered logic-level inverter for digital signal conditioning in microcontroller I/O expansion and bus interface circuits.
For engineers reviewing the MM74HCT04MTC datasheet, pinout, applications, or equivalent options, key selection criteria include its LS-TTL plug-in replacement capability, 20 µA max quiescent ICC, 4.2 V min VOH at 4.0 mA load, TSSOP-14 JEDEC MO-153 package, and guaranteed 25 ns max propagation delay over full temperature range.
Technical Context
The MM74HCT04MTC implements six independent inverting buffers with triple-buffered output stages to improve noise immunity and drive strength. Its input thresholds (VIH = 2.0 V, VIL = 0.8 V) match LS-TTL logic families, enabling direct interfacing without level-shifting.
All inputs feature internal clamp diodes to VCC and GND for ESD protection. The device operates within a 4.5–5.5 V supply window and maintains guaranteed DC output voltage levels (VOH ≥ 3.98 V, VOL ≤ 0.26 V at 4.0 mA) across –40°C to +85°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|

| Supply Voltage | 4.5–5.5 V - compatible with standard 5 V digital systems and tolerant of rail variation |
| Propagation Delay | 25 ns max (tPLH/tPHL) at 5 V, CL = 50 pF, –40°C to +85°C - ensures timing predictability in synchronous logic |
| Output Drive | ±25 mA per pin - supports direct driving of LS-TTL loads or small capacitive buses |
| Quiescent ICC | 20 µA max - enables ultra-low static power in battery-backed or standby-critical designs |

Equivalent & Alternatives
The following parts are listed as comparable options for similar hex inverter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74HCT04DR | SOIC-14 package (M14A), identical electrical specs, same 25 ns max tPLH/tPHL, but 1.5 mm taller profile | Preferred where board height is unconstrained and reflow compatibility with legacy SOIC footprints is required | Select when footprint compatibility with existing SOIC-14 land patterns is mandatory |
| 74VHC04MTCX | Higher speed (11 ns typ), wider VCC range (2–5.5 V), but lower output drive (±8 mA) and no LS-TTL input thresholds | Suitable for mixed-voltage 3.3 V systems but not direct LS-TTL replacement; requires input voltage validation | Select only when operating below 4.5 V or when higher speed outweighs LS compatibility needs |
Compared with SN74HCT04DR and 74VHC04MTCX, the MM74HCT04MTC uniquely combines LS-TTL pin/out compatibility, TSSOP-14 space savings, and guaranteed industrial temperature performance - making it optimal for retrofitting legacy 74LS04-based designs into compact, thermally demanding layouts.

FAQ
What is the maximum operating temperature range for the MM74HCT04MTC?
The MM74HCT04MTC is rated for continuous operation from –40°C to +85°C. This industrial temperature range is guaranteed per the Recommended Operating Conditions table in the official datasheet, and all DC and AC specifications-including propagation delay, VOH, and VOL-are validated across this full span. The MM74HCT04MTC maintains stable performance without derating up to +85°C ambient, making it suitable for enclosed industrial enclosures and under-hood automotive auxiliary modules.
Does the MM74HCT04MTC support 3.3 V operation?
No, the MM74HCT04MTC does not support 3.3 V operation. Its Recommended Operating Conditions specify a minimum supply voltage of 4.5 V and maximum of 5.5 V. At 3.3 V, input thresholds (VIH = 2.0 V, VIL = 0.8 V) would violate the required VIH > 0.7 × VCC (2.31 V), risking unreliable HIGH detection. For 3.3 V systems, consider the 74VHC04 or SN74LVC04A instead. The MM74HCT04MTC is strictly a 5 V logic device.
Is the MM74HCT04MTC pin-compatible with the 74LS04?
Yes, the MM74HCT04MTC is pin-compatible with the 74LS04. Both devices use identical 14-pin DIP/SOIC/TSSOP pinouts: inputs on pins 1, 3, 5, 9, 11, 13 and outputs on pins 2, 4, 6, 8, 10, 12, with VCC on pin 14 and GND on pin 7. The MM74HCT04MTC also matches LS-TTL input thresholds and output drive capability, enabling direct replacement without layout changes-confirmed in the General Description and Connection Diagram sections of the MM74HCT04 datasheet.
What is the typical power dissipation of the MM74HCT04MTC at 5 MHz?
The MM74HCT04MTC dissipates 3.7 mW typical at 5 MHz, as specified in the Features section of the datasheet. This value accounts for both dynamic (CPD × VCC² × f) and quiescent (ICC × VCC) components. At 5 V supply and 5 MHz toggle rate, the 20 pF power dissipation capacitance (CPD) dominates, yielding ~3.7 mW total. This is over 100× lower than equivalent 74LS04 consumption, significantly reducing thermal load in high-density logic arrays.
Are there internal ESD protection diodes on the MM74HCT04MTC inputs?
Yes, the MM74HCT04MTC includes internal clamp diodes on all inputs connected to VCC and GND, as explicitly stated in the General Description: "All inputs are protected from static discharge by internal diodes to VCC and ground." These diodes allow ±20 mA clamp current (per Absolute Maximum Ratings), enabling robust handling of common ESD events per IEC 61000-4-2 Level 2 without external protection-critical for industrial field I/O and sensor interface applications.
