E1466DHO-P8

Overview

The Microchip Technology E1466DHO-P8 is a digital trimmer clock generator IC designed for application-specific timing requirements. It operates at a maximum frequency of 32 kHz with a single output circuit and a 1:1 input-to-output ratio. The device supports a supply voltage range of 1.1 V to 2.2 V and functions within an operating temperature range of -20°C to +70°C. It is housed in an 8-pin PDIP package (8-DIP, 0.300 inch width) intended for through-hole mounting. This component does not include a Phase-Locked Loop (PLL).

Feature Summary

• Digital trimmer functionality for precise clock generation up to 32 kHz.
• Single circuit configuration with no differential inputs or outputs.
• Low voltage operation supported by a 1.1 V to 2.2 V supply range.
• Through-hole compatible 8-PDIP package for standard board integration.

Applications

• Application-specific clock timing circuits requiring digital adjustment.
• Low-frequency signal generation in consumer electronics.
• Timing references in industrial control systems operating within the specified temperature range.

Procurement Notes

Verify the specific suffix 'HO' against official Microchip documentation to confirm exact temperature grade and material compliance details. Ensure the ordering code matches the required 8-PDIP package dimensions. Cross-reference the manufacturer part number with distributor listings to confirm current availability status and lead times prior to procurement.

Selection Notes

Select this component when a fixed 32 kHz digital trimmer clock is required without PLL complexity. Confirm that the system power supply remains within the 1.1 V to 2.2 V window. Verify that the through-hole 8-PDIP footprint aligns with the PCB design constraints. Ensure the ambient operating environment stays between -20°C and +70°C.

Part Context

This part belongs to the E1466D family of digital trimmer clock generators from Microchip Technology. These devices are engineered to provide stable, adjustable clock signals for specialized timing applications where traditional oscillators may be insufficient or overly complex. The series focuses on simplicity and direct digital control capabilities.

Replacement Considerations

Direct replacements must match the 32 kHz frequency, 1.1-2.2 V supply range, and 8-PDIP package. Verify pin compatibility and electrical characteristics before substituting with other digital trimmer ICs from different manufacturers.
