18QHTF21-74.00363-PD

Overview

The 18QHTF21-74.00363-PD is a crystal oscillator manufactured by Mercury Electronic Ind. Co. Ltd. It operates at a frequency of 74.00363 MHz with an LVCMOS output logic level. The device requires a supply voltage of 1.8V and features a Standby (Power Down) control function. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0mm x 1.6mm.

Feature Summary

• Supports low-voltage operation at 1.8V for energy efficiency
• Includes standby functionality to reduce power consumption during idle periods
• Utilizes LVCMOS output logic for standard digital interface compatibility

Applications

• General clock signal generation in embedded systems
• Timing reference for digital communication interfaces
• Clock source for microcontrollers and processors requiring precise timing

Procurement Notes

Verify the exact frequency tolerance and load capacitance requirements against your specific circuit design before procurement. Ensure that the 1.8V supply voltage aligns with your system's power rails. Confirm that the 4-SMD no-lead package footprint matches your PCB layout constraints. Check for any specific manufacturing date codes or lot traceability requirements if applicable to your quality standards.

Selection Notes

Select this component when a precise 74.00363 MHz clock signal is required in space-constrained applications. The 1.8V operating voltage makes it suitable for modern low-power digital circuits. The integrated standby feature allows for dynamic power management. Consider the small 2.0x1.6mm footprint when designing high-density boards where space optimization is critical.
