18QHTF21-74.180-OE

Overview

The 18QHTF21-74.180-OE is a standard crystal oscillator manufactured by Mercury Electronic Ind. Co., Ltd. It operates at a frequency of 74.18 MHz and utilizes LVCMOS output logic. The device functions with a supply voltage of 1.8V and includes enable/disable control capabilities. It is housed in a compact 4-SMD, No Lead package, designed for surface-mount applications requiring precise timing signals.

Feature Summary

• LVCMOS output logic for digital interface compatibility
• Integrated enable and disable functionality for power management
• Compact 4-SMD no lead surface mount package design

Applications

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

Procurement Notes

Verify the specific part number against official Mercury Electronic documentation to ensure accuracy. Confirm that the 1.8V supply requirement and LVCMOS output levels match your target circuit design specifications before procurement.

Selection Notes

Select this component when a 74.18 MHz clock source is required with low voltage operation. Ensure the PCB layout supports the 4-SMD no lead package dimensions and that the system logic levels are compatible with LVCMOS standards.

Part Context

This oscillator belongs to the Mercury Electronic SMD oscillator series, which includes various models like the 18QHTF21-74.130-OE and 18QHTF21-8.300-OE. These components share similar packaging and functional characteristics but differ in operating frequencies and specific electrical parameters.

Replacement Considerations

Direct substitutes include other 74.18 MHz LVCMOS oscillators in 4-SMD packages from Mercury Electronics or other manufacturers, provided voltage and pinout compatibility are verified.
