E1466DHO-DIT

Overview

The E1466DHO-DIT is a digital trimmable clock generator IC manufactured by Microchip Technology. It operates within a supply voltage range of 1.1V to 2.2V and provides a single output at a maximum frequency of 32kHz. The device features a 1:1 input-to-output ratio without differential signaling capabilities. Designed for through-hole mounting, it is housed in an 8-PDIP package with dimensions of 0.300 inches (7.62mm). The component supports an operating temperature range from -20°C to 70°C.

Feature Summary

• Digital trimming capability for precise frequency adjustment
• Low voltage operation between 1.1V and 2.2V
• Single circuit configuration with 32kHz maximum frequency
• Through-hole 8-PDIP package for standard board mounting

Applications

• Real-time clock circuits requiring stable 32kHz references
• Low-power embedded systems with limited voltage rails
• Industrial control modules operating in moderate temperature environments

Procurement Notes

Verify the specific ordering suffix 'HO' against official Microchip documentation to confirm material or temperature grade variations compared to standard variants. Ensure compatibility with existing 8-DIP footprints during procurement planning. Confirm end-of-life status if applicable, as timing components may have long-term availability constraints.

Selection Notes

Select this component when a fixed 32kHz output with digital adjustability is required under low-voltage conditions. The 8-PDIP package suits prototyping or applications where surface-mount space is not critical. Verify that the 1.1V minimum supply meets the system's power budget and that the -20°C lower limit aligns with environmental requirements.

Part Context

This part belongs to Microchip's application-specific clock and timing family. It serves as a dedicated oscillator solution for systems needing a precise, trimmable reference frequency without the complexity of programmable PLL-based synthesizers. The 8-pin DIP form factor facilitates easy integration into legacy or through-hole dominated designs.

Replacement Considerations

Direct pin-compatible replacements must match the 8-PDIP package, 1.1V-2.2V supply range, and 32kHz output frequency. Verify that any substitute maintains the digital trimming interface and single-ended output characteristics. Cross-reference Microchip's current portfolio for active alternatives if this specific suffix is discontinued.
