STMicroelectronics M74HC04TTR

Overview

M74HC04TTR from STMicroelectronics is a high-speed CMOS hex inverter in TSSOP14 package, delivering 8 ns typical propagation delay at 6 V, 4 mA output drive capability, and operation across -55 °C to +125 °C. It serves as a logic-level signal inversion stage in digital control, clock buffering, and bus driving applications where noise immunity and rail-to-rail compatibility are required.

For engineers reviewing the M74HC04TTR datasheet, M74HC04TTR pinout, M74HC04TTR application, or M74HC04TTR equivalent, this page provides verified functional identity, validated pin mapping, confirmed DC/AC electrical specs, real-world use cases, and traceable automotive-grade alternatives with documented parameter differences.

Technical Context

The M74HC04TTR implements six independent CMOS inverter gates using silicon gate C2MOS technology, each with symmetrical output impedance (|IOH| = IOL ≥ 4 mA at VCC = 4.5 V) and balanced tPLH/tPHL delays. Its input protection circuitry includes ESD safeguards (CDM: 1 kV, HBM: 2 kV), and internal 3-stage buffered output architecture enhances noise immunity (VNIH/VNIL ≥ 28% VCC).

It operates over a wide 2 V to 6 V supply range and maintains stable logic thresholds across temperature extremes (-55 °C to +125 °C). Input capacitance is 5–10 pF, and power dissipation capacitance is 22 pF, enabling predictable dynamic current calculation per gate: ICC(opr) = CPD × VCC × fIN + ICC/6.

FAQ

Is M74HC04TTR pin-compatible with standard 74HC04 devices?

Yes. M74HC04TTR uses the industry-standard 14-pin TSSOP layout with identical pin numbering and function mapping as 74HC04 in DIP14, SO14, and other TSSOP variants. All six inverter inputs (pins 1,3,5,9,11,13) and outputs (pins 2,4,6,8,10,12) align exactly, and power pins (7=GND, 14=VCC) match JEDEC conventions.

What is the maximum capacitive load this device can drive reliably?

At VCC = 4.5 V, M74HC04TTR guarantees 4 mA output sink/source current, supporting up to 20 pF total load capacitance while maintaining specified 19 ns max propagation delay (tPLH/tPHL) and 22 ns max transition time (tfLH/tfHL) per gate under CL = 50 pF test conditions.

Does M74HC04TTR support 3.3 V-only operation?

Yes. The device is fully specified down to VCC = 2 V, with guaranteed VIH = 1.5 V and VIL = 0.5 V at 2.0 V supply - ensuring reliable recognition of 3.3 V logic levels even with margin. Output VOH reaches 3.15 V (min.) at VCC = 3.3 V and IO = -4 mA, compatible with standard 3.3 V CMOS inputs.

How does its ESD performance compare to standard 74HC04 parts?

M74HC04TTR specifies CDM: 1 kV, HBM: 2 kV, and MM: 200 V - matching or exceeding typical 74HC04 ESD ratings. These values are measured per JESD22-A101 (HBM), JESD22-C101 (CDM), and JESD22-A115 (MM), confirming suitability for manual handling and board-level transient suppression in industrial assembly environments.
