M244TCN 4.000000

Overview

The M244TCN 4.000000 is a standard crystal oscillator manufactured by MtronPTI, designed for precise clock signal generation in electronic circuits. It operates at a fixed frequency of 4 MHz and utilizes HCMOS output logic, ensuring compatibility with TTL standards. The device functions on a single 3.3V supply voltage and features a tri-state output capability, allowing for an output enable function to control signal transmission. It is housed in a compact 4-SMD, no-lead package with dimensions of 5x7 mm, utilizing leadless ceramic construction for reliable surface-mount assembly.

Feature Summary

• HCMOS/TTL compatible output logic for broad digital interface integration
• Tri-state output configuration enabling active high/low/z states via enable control
• Leadless ceramic SMD package design supporting automated surface-mount processing

Applications

• General-purpose clock signal distribution in embedded systems
• Timing reference sources for microcontrollers and digital processors
• Synchronization modules requiring stable 4 MHz base frequencies

Procurement Notes

Verify the specific frequency suffix matches the required 4.000000 MHz specification, as the M244TCN series supports multiple frequency options. Confirm the package type is the 4-SMD no-lead variant and that the operating voltage aligns with the 3.3V requirement. Ensure the manufacturer is identified as MtronPTI to guarantee component authenticity and performance consistency.

Selection Notes

Select this component when a fixed 4 MHz timing source is required with low power consumption and standard digital logic compatibility. The tri-state feature is advantageous for bus-sharing applications where multiple oscillators may connect to a common line. Consider the 5x7 mm footprint for board space constraints and verify thermal management requirements for the intended operating environment.

Part Context

This part belongs to the M244TCN family of standard crystal oscillators from MtronPTI. The series offers various frequency options within a consistent 5x7 mm leadless ceramic package. These oscillators are engineered for general-purpose applications requiring reliable clock signals without the complexity or cost of temperature-compensated variants.

Replacement Considerations

Direct substitutes must match the 4 MHz frequency, 3.3V operation, HCMOS output, and 5x7mm SMD package. Verify pinout compatibility and electrical characteristics before substitution.
