M244TAN 8.000000

Overview

The M244TAN 8.000000 is a standard crystal oscillator manufactured by MtronPTI, designed for precise clock signal generation in electronic circuits. It operates at a nominal frequency of 8 MHz and utilizes HCMOS or TTL output types to ensure compatibility with various digital logic families. The device functions at a supply voltage of 3.3V and features a tri-state output capability, allowing for an output enable function to manage bus contention or power states effectively. Housed in a compact 4-SMD, No Lead package, this leadless ceramic component offers a small form factor suitable for space-constrained applications. It represents a reliable solution for timing requirements in consumer electronics, industrial controls, and communication systems where stable clock sources are essential.

• Communication interface synchronization
• Industrial control system timing

Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your design specifications before procurement. Ensure that the 3.3V operating voltage aligns with your system's power rails. Confirm that the HCMOS/TTL output levels are compatible with the input thresholds of your downstream logic components. Check the physical dimensions of the 4-SMD no-lead package to ensure it fits within your PCB layout constraints. Review the manufacturer's datasheet for detailed electrical characteristics and recommended soldering profiles to guarantee reliability.

Selection Notes

Select this oscillator when a fixed 8 MHz frequency is required for digital timing applications. Consider the HCMOS/TTL output type if interfacing directly with standard logic gates or microcontrollers without additional level shifting. The tri-state feature is advantageous for systems requiring multiple clock sources on a shared bus. Evaluate the 3.3V supply requirement against available power planes. The leadless ceramic package offers thermal stability and a small footprint, making it suitable for dense PCB designs. Compare jitter specifications if high-frequency precision is critical for your application.

Part Context

This component belongs to the M244 series of clock oscillators from MtronPTI, which are known for their reliability and compact size. The M244 series typically includes various frequency options and output types to suit different design needs. As a standard product, it is widely available through distributors. The series is designed to replace older through-hole oscillators with surface-mount solutions, offering improved performance and ease of automated assembly.
