Overview
The 18QHTF21-7.400-OE is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 7.4 MHz and utilizes LVCMOS output logic levels. The device is designed for low-voltage applications, functioning with a supply voltage of 1.8V. It features an enable/disable control pin for power management flexibility. The component is housed in a compact 4-SMD, No Lead package with dimensions of 2.0x1.6 mm, suitable for surface-mount technology (SMT) assembly on printed circuit boards.
Feature Summary
- Supports enable/disable functionality via dedicated control pin
- Utilizes LVCMOS output interface for digital compatibility
- Designed for low-voltage operation at 1.8V supply
- Compact surface-mount form factor
Applications
- Portable electronic devices requiring low power consumption
- Digital signal processing circuits
- Microcontroller clock sources
- Communication equipment timing references
Procurement Notes
Verify the specific suffix 'OE' indicates the Enable/Disable feature when sourcing replacements. Confirm that the 1.8V supply requirement matches the target system's voltage rails. Ensure the 2.0x1.6 mm footprint aligns with the PCB layout constraints. Check for RoHS compliance status if environmental regulations apply to the final product assembly.
Selection Notes
Select this component when a small form factor and low voltage operation are critical. The enable/disable feature allows for dynamic power management in battery-operated systems. Ensure the application requires LVCMOS logic levels rather than other output types like HCMOS or CMOS. Verify that the 7.4 MHz frequency meets the precise timing requirements of the design.
Part Context
Mercury Electronics specializes in quartz crystal and oscillator manufacturing. This part belongs to their XO series, focusing on standard frequency generation. The company has decades of experience in Taiwan's quartz industry. The 18QHTF21 series represents their compact SMD oscillator offerings.
Replacement Considerations
The datasheet archive lists 18QHTF21-40.080-PD as an equivalent or alternate part number within the same family. Both parts share similar packaging and voltage characteristics but differ in frequency and output control suffixes.
