Product details

Overview

MM74HCU04MTCX from onsemi is a hex unbuffered inverter IC in the 74HCU logic family, designed for high-speed digital signal inversion with CMOS power efficiency. It delivers 7 ns typical propagation delay at 5 V, supports 2–6 V supply operation, drives up to 15 LS-TTL loads, and operates across –55°C to +125°C for industrial timing and oscillator circuits.

For engineers reviewing the MM74HCU04MTCX datasheet, pinout, applications, or equivalent options, this page provides verified package mapping (TSSOP-14), real-world AC/DC electrical specs, functional compatibility with 74LS logic, and validated alternatives for logic-level translation and waveform shaping tasks.

Technical Context

The MM74HCU04MTCX implements six independent unbuffered CMOS inverter stages using silicon-gate technology, enabling LS-TTL–speed performance without TTL's power penalty. Its input structure includes diode clamps to V_CC and GND for ESD protection, and its output stage is rated for ±25 mA DC per pin.

This device operates over a wide V_CC range (2.0–6.0 V) and maintains guaranteed VIH/VIL thresholds across temperature (e.g., VIH = 4.8 V min at V_CC = 6.0 V, TA = −55°C to +125°C). Propagation delay degrades predictably with voltage and load-13 ns max at 5 V/15 pF, 20 ns max at 6 V/50 pF, and 120 ns at 2 V/50 pF.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CC Range	2.0 V to 6.0 V - Enables direct interface with 3.3 V and 5 V systems without level shifters.
t_PHL/t_PLH	7 ns typical / 13 ns max at 5 V, 15 pF - Supports >30 MHz toggle rates in clean logic paths.
Fanout	15 LS-TTL loads - Sufficient drive strength to replace multiple 74LS04 gates without buffering.
I_IN Max	±1.0 µA at 6 V - Near-zero static input current enables high-impedance node interfacing and low-leakage bias networks.
Operating Temp	−55°C to +125°C - Qualified for under-hood automotive, industrial control, and aerospace subsystems.
P_D (TSSOP)	833 mW - Thermal limit defined for TSSOP-14 package; requires ≤25°C/W board-level θ_JA for full-power operation.
V_OH/V_OL	5.5 V min / 0.5 V max at 6 V, I_OUT = 5.2 mA - Ensures robust noise margin (>1.5 V) in 6 V logic rails.

14	Inverter 6 Output	Final output stage; used in crystal oscillator feedback loops per Figure 2 of datasheet.

Key Features

Feature	Design Value
Unbuffered architecture	Enables precise phase control in oscillator and Schmitt-trigger designs where gate delay must be predictable and minimal.

Equivalent & Alternatives

The following parts are listed as comparable options for similar hex inverter applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
SN74HCU04DR	SOIC-14 package (vs. TSSOP-14); identical AC/DC specs and pinout; 1077 mW P_D rating.	Better thermal dissipation in high-density boards; larger footprint limits use in space-constrained portable designs.	Select SN74HCU04DR when board layout accommodates SOIC and higher power handling is needed.
74LVC04PW,118	Lower V_CC range (1.65–5.5 V); 3.5 ns typical t_PD; 50 Ω output impedance; not pin-compatible with 74LS family.	Optimized for 1.8 V/3.3 V systems only; unsuitable for mixed-voltage 5 V legacy interfaces or crystal oscillator use above 10 MHz.	Choose 74LVC04PW,118 only for new 3.3 V-only designs requiring faster speed and lower dynamic power.

Compared with SN74HCU04DR and 74LVC04PW,118, the MM74HCU04MTCX uniquely balances 74LS pin compatibility, wide 2–6 V operation, and TSSOP-14 compactness-making it optimal for industrial upgrades and mixed-voltage oscillator designs where layout reuse and voltage flexibility are critical.

FAQ

What is the maximum operating supply voltage for MM74HCU04MTCX?

The absolute maximum V_CC rating for MM74HCU04MTCX is +6.5 V, but the recommended operating range is 2.0 V to 6.0 V. Operation at 6.0 V is fully characterized across temperature and ensures guaranteed VOH/VOL, VIH/VIL, and propagation delay performance per the datasheet's DC and AC Electrical Characteristics tables.

Is MM74HCU04MTCX pin-compatible with standard 74LS04 devices?

Yes, MM74HCU04MTCX is functionally and pin-out compatible with the 74LS04. All six inverter channels map identically to pins 1–2, 3–4, 5–6, 9–10, 11–12, and 13–14, with shared V_CC (Pin 14) and GND (Pin 7). This allows direct replacement in existing LS-TTL designs without PCB modification.

Can MM74HCU04MTCX be used in crystal oscillator circuits?

Yes, MM74HCU04MTCX is explicitly recommended for crystal oscillator applications (see Figure 2 in the datasheet). Its unbuffered design, low input capacitance (≤15 pF), and rail-to-rail output swing make it suitable for Pierce oscillator topologies driving fundamental-mode crystals up to 20 MHz with appropriate load capacitors and feedback resistors.

What is the thermal limitation of MM74HCU04MTCX in TSSOP-14 package?

The MM74HCU04MTCX in TSSOP-14 (Case 948G) has a maximum power dissipation (P_D) of 833 mW at TA = 25°C. Derating is required above 25°C-approximately 10.2 mW/°C-so at 85°C ambient, usable power drops to ~220 mW. Proper PCB copper area and thermal vias are essential for sustained operation near this limit.

Does MM74HCU04MTCX support operation at –55°C?

Yes, MM74HCU04MTCX is fully specified for operation from –55°C to +125°C. All key parameters-including VIH/VIL thresholds, propagation delay, and output drive capability-are guaranteed across this full industrial/military temperature range, making it suitable for under-hood automotive and outdoor infrastructure applications.
