E1466DAO-S8

Overview

The E1466DAO-S8 is a digital trimmable clock generator manufactured by Microchip Technology. It provides a single output at a maximum frequency of 32kHz with a 1:1 input-to-output ratio. The device operates on a supply voltage ranging from 1.1V to 2.2V and supports surface mount installation in an 8-SOIC package (0.154 inch width). It functions without a Phase-Locked Loop (PLL) and lacks differential inputs or outputs. The component is rated for an operating temperature range of -20°C to 70°C.

Feature Summary

• Digital trimming capability for precise frequency adjustment
• Single circuit configuration with 1:1 input/output ratio
• Low voltage operation between 1.1V and 2.2V
• Surface mount 8-SOIC package

Applications

• Application specific clock timing circuits
• Systems requiring 32kHz digital trimmable references

Procurement Notes

Verify the exact ordering suffix against official Microchip documentation to confirm pinout and electrical specifications. Confirm RoHS compliance status as historical data for similar variants may vary. Ensure the 8-SOIC package dimensions match the target PCB footprint requirements before procurement.

Selection Notes

Select this component when a low-voltage, digitally adjustable 32kHz clock source is required in a surface-mount form factor. Compare the 1.1V to 2.2V supply range against system power rails. Verify that the -20°C to 70°C operating temperature range meets environmental constraints.

Part Context

This part belongs to the E1466D series of digital trimmable clock generators. It shares core functionality with other variants in the family but differs in packaging, specifically utilizing the 8-SOIC case instead of through-hole options like PDIP.

Replacement Considerations

Check for direct cross-references within the E1466D family. Verify if alternative packages such as 8-DIP are functionally equivalent for the specific application design.
