MH44FAD-R 40.000000

Overview

The MH44FAD-R-40.000MHZ is a hybrid clock oscillator manufactured by MtronPTI, designed for standard digital logic applications. It operates at a nominal frequency of 40 MHz with a tolerance of ±50 ppm and provides an output load of 50 pF. The device supports both HCMOS and TTL output logic levels and functions at a supply voltage of 5V. It utilizes a 4-pin DIP module package configured for through-hole mounting. This component is part of the M3H & MH series, offering low jitter performance and a tristate option for flexible system integration.

Feature Summary

• Supports both HCMOS and TTL output logic levels for broad compatibility
• Features a low jitter specification for stable signal generation
• Includes a tristate option to enable or disable the output signal
• Utilizes a compact 4-pin DIP module form factor for through-hole mounting

Applications

• General-purpose digital logic timing circuits
• Microprocessor clock generation systems
• Communication interface synchronization
• Test and measurement equipment timing references

Procurement Notes

Verify the specific suffix requirements when ordering, as the -R designation indicates RoHS compliance. Confirm that the 4-pin DIP package aligns with your PCB footprint and assembly processes. Ensure the 5V supply voltage matches your system design constraints. Check for any application-specific variations in frequency stability or temperature range if operating in extreme environments. Consult official MtronPTI documentation for detailed pinout and electrical specifications before finalizing procurement.

Selection Notes

Select this component when a reliable 40 MHz reference is needed for HCMOS or TTL-based designs. The 4-pin DIP package suits prototyping and through-hole manufacturing workflows. Consider the ±50 ppm tolerance for general timing applications where high precision is not critical. The tristate feature allows for easy bus management in multi-clock systems. Evaluate thermal requirements against the wide operating temperature range if deployed in industrial settings.

Part Context

This oscillator belongs to the M3H & MH series from MtronPTI, which focuses on hybrid clock oscillators. These components are characterized by their robust construction and compatibility with standard logic families. The series offers various frequency options within a standardized package format, facilitating easy replacement and design reuse across different electronic products requiring precise timing signals.

Replacement Considerations

Direct substitutes must match the 40 MHz frequency, 5V operation, and 4-pin DIP package. Verify that alternative components support both HCMOS and TTL outputs if dual compatibility is required. Ensure the replacement maintains similar jitter characteristics and includes a tristate function if used in bus-oriented designs. Cross-reference pinouts to guarantee mechanical and electrical compatibility without circuit modification.
