The device supports a supply voltage of 1.8V and features a power-down standby mode for energy efficiency. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0mm x 1.6mm. This component is designed for standard clock signal applications requiring precise timing.

Feature Summary

• Supports low-voltage operation at 1.8V
• Includes power-down standby functionality
• Provides LVCMOS output compatibility

Applications

• General clock signal generation
• Embedded system timing references
• Digital circuit synchronization

Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your design specifications before procurement. Confirm that the 1.8V supply voltage aligns with your system's power rails. Ensure the 4-SMD no-lead package footprint matches your PCB layout constraints to guarantee proper soldering and mechanical stability during assembly.

Selection Notes

Select this component when a 7.3333 MHz clock source is required with low power consumption capabilities. The LVCMOS interface ensures compatibility with standard digital logic families. Consider the small 2.0x1.6mm package size if space constraints are critical. Verify that the operating temperature range meets your environmental conditions prior to integration into the final product design.

Part Context

This part belongs to the 18QHTF21 series of surface-mount oscillators from Mercury Electronics. The series offers various frequencies within a standardized 4-SMD no-lead form factor. These components are engineered for reliability in consumer electronics and industrial applications where stable timing signals are essential for proper system operation and data integrity.

Replacement Considerations

Direct substitutes include other 18QHTF21 series variants with identical pinouts and electrical characteristics but different frequencies. Cross-reference with similar 2.0x1.6mm LVCMOS oscillators from other manufacturers only if they match the exact voltage, current, and frequency specifications.
