18QHTF21-24.0004-PD

Oscillators Overview

The 18QHTF21-24.0004-PD is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd, operating at a frequency of 24.0004 MHz. It utilizes LVCMOS output logic and functions with a supply voltage of 1.8V. The device features a power-down capability for standby mode control. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0x1.6 mm.

Oscillators Feature Summary

• Supports LVCMOS output logic levels
• Includes power-down functionality for standby operation
• Compact surface-mount package design

Oscillators Applications

• General clock signal generation
• Digital circuit timing reference
• Embedded system clock sources

Oscillators Procurement Notes

Verify the specific suffix 'PD' indicates the power-down feature when sourcing replacements. Confirm the 1.8V supply requirement matches the target circuit design. Ensure the 2.0x1.6mm footprint aligns with the PCB layout constraints. Check for availability from authorized distributors as stock levels vary.

Oscillators Selection Notes

Select this component when a low-voltage 1.8V LVCMOS oscillator is required. The power-down feature is essential for applications needing standby current reduction. Consider the small 2.0x1.6mm package size for space-constrained designs. Verify that the 24.0004 MHz frequency meets the precise timing requirements of the application.

Oscillators Part Context

This part belongs to the 18QHTF21 series of standard crystal oscillators from Mercury Electronics. The series offers various frequencies and supply voltages. The 'PD' suffix typically denotes power-down capability, distinguishing it from non-power-down variants within the same family.

Oscillators Replacement Considerations

Direct substitutes include other 18QHTF21 series parts with matching 24.0004 MHz frequency and 1.8V supply. Ensure replacement parts also feature LVCMOS outputs and the PD power-down function. Verify package compatibility for direct pin-to-pin replacement.
