The device functions with a supply voltage of 1.8V and features enable/disable control capabilities. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0mm x 1.6mm.

Feature Summary

• Supports LVCMOS output logic for digital interface compatibility
• Includes enable and disable functionality for power management
• Utilizes a lead-free SMD package for surface mount assembly

Applications

• General purpose clock signal generation
• Digital circuit timing references
• Embedded system clock sources

Procurement Notes

Verify the specific suffix against official manufacturer documentation to confirm electrical characteristics and pinout configuration. Ensure that the ordering information matches the required frequency tolerance and operating temperature range specified in the datasheet before finalizing procurement orders.

Selection Notes

Select this component when a low-voltage 1.8V operation is required for clock generation. Consider the small 2.0x1.6mm footprint for space-constrained designs. Verify that the LVCMOS output level aligns with the input requirements of the connected load circuitry.

Part Context

This part belongs to the 18QHTF21 series of standard crystal oscillators from Mercury Electronics. The series offers various frequencies and voltage options. The 'OE' suffix typically denotes an enable pin configuration, distinguishing it from other variants within the same physical package family.

Replacement Considerations

Direct substitutes include other 18QHTF21 series parts with matching 8.502 MHz frequency and 1.8V supply voltage. Ensure replacement components maintain the same LVCMOS output type and 4-SMD package dimensions for mechanical compatibility.
