18QHTF21-74.113-PD

Overview

The 18QHTF21-74.113-PD is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 74.113 MHz and utilizes LVCMOS output logic. The device functions with a supply voltage of 1.8V and includes a standby or power-down feature for energy management. It is housed in a compact 4-SMD, no lead package with dimensions of 2.0x1.6 mm.

Feature Summary

• Supports LVCMOS output logic for digital interface compatibility
• Includes standby mode functionality to reduce power consumption
• Utilizes a surface-mount package design for automated assembly

Applications

• General clock signal generation in electronic circuits
• Timing reference sources for digital systems
• Embedded devices requiring precise frequency control

Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against the target circuit design before procurement. Confirm that the 1.8V supply voltage aligns with the system power rails. Ensure the PCB footprint matches the 2.0x1.6 mm SMD package dimensions to prevent mounting issues during assembly.

Selection Notes

Select this component when a low-voltage 1.8V operation is required alongside a specific 74.113 MHz frequency. Consider the LVCMOS output type for direct interfacing with compatible logic families. Evaluate the need for power-down capabilities if energy efficiency is a priority in the application environment.

Part Context

This part belongs to the 18QHTF21 series from Mercury Electronics, which offers various frequencies within a standardized 2.0x1.6 mm form factor. The series typically supports LVCMOS outputs and 1.8V operation, providing a consistent platform for timing applications across different frequency requirements.

Replacement Considerations

Direct substitutes include other 18QHTF21 variants with identical pinout and electrical characteristics but different frequencies, such as 18QHTF21-6.000-PD or 18QHTF21-96.768-PD, provided the frequency difference is acceptable for the application.
