18QHTF21-6.660-OE

Overview

The 18QHTF21-6.660-OE is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 6.66 MHz and utilizes LVCMOS output logic. The device functions with a supply voltage of 1.8V and includes an enable/disable control feature. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0x1.6 mm.

Feature Summary

• Integrates LVCMOS output logic for digital signal compatibility
• Features integrated enable and disable control functionality
• Utilizes a surface-mount 4-SMD no-lead package design

Applications

• General purpose timing circuits
• Embedded system clock generation
• Consumer electronics timing references

Procurement Notes

Verify the specific suffix OE against the manufacturer's official documentation to confirm the exact tape-and-reel packaging configuration. Ensure the 1.8V supply requirement aligns with the target circuit design. Confirm the 6.66 MHz frequency specification matches the application requirements before procurement.

Selection Notes

Select this component when a low-voltage 1.8V operation is required alongside precise 6.66 MHz timing. The small 2.0x1.6 mm footprint makes it suitable for space-constrained designs. Verify that the LVCMOS output swing is compatible with the receiving logic inputs of the target system.

Part Context

This part belongs to the Mercury Electronic 18QHTF series of surface-mount oscillators. The series typically offers various frequencies and voltage options within a standardized small outline package format. The manufacturer specializes in quartz-based frequency control products including crystals and oscillators.

Replacement Considerations

Direct substitutes include other 6.66 MHz LVCMOS oscillators in 2.0x1.6mm packages from different manufacturers. Ensure equivalent electrical specifications such as 1.8V supply and enable pin functionality are matched during replacement.
