EP1810LI-35

Overview

The EP1810LI-35 is an Altera EPLD from the EP1810 family, manufactured by Rochester Electronics. It features a PAL-type architecture with 18 dedicated inputs and 8 outputs in a 20-pin PLCC package. The device operates at a maximum clock frequency of 17.9 MHz with a propagation delay of 35 ns. It supports CMOS logic levels and functions within a temperature range of -40°C to 85°C.

Feature Summary

• PAL-type programmable logic architecture
• CMOS technology for low power consumption
• High-speed operation up to 17.9 MHz

Applications

• Digital logic replacement
• Interface bridging
• Address decoding

Procurement Notes

Verify the specific suffix 'LI-35' against official Rochester Electronics documentation to confirm pinout and electrical characteristics. Ensure the component matches the original Altera specifications for your design integration. Confirm RoHS compliance status if required for your manufacturing process.

Selection Notes

Select this component when replacing obsolete Altera EP1810 devices in existing designs. It provides a direct functional equivalent for applications requiring 18 inputs and 8 outputs. Verify that the 35 ns speed grade meets the timing requirements of your system clock.

Part Context

Rochester Electronics sustains production of legacy semiconductors like the EP1810 family. This part ensures supply continuity for products that rely on older programmable logic technologies no longer actively marketed by the original manufacturer.

Replacement Considerations

This component serves as a direct replacement for the Altera EP1810LI-35. Verify compatibility with other variants in the EP1810 series if pinouts differ.
