Complex Programmable Logic Devices Procurement Notes

Verify the specific ordering code ATF750C-10SU-T against official Microchip documentation to confirm package type and speed grade. Ensure compliance with environmental standards if required. Check for any export control restrictions applicable to this component before procurement.

Complex Programmable Logic Devices Selection Notes

Select this device when a 24-pin CPLD with 10 ns speed and industrial temperature range (-40°C to +85°C) is required. It serves as a direct replacement for older ATV750/L devices while offering enhanced logic flexibility and lower pin count. Consider the SOIC package for surface mount applications.

Complex Programmable Logic Devices Part Context

The ATF750C series is part of Microchip's high-performance CPLD family, designed to replace legacy 22V10 PALs with greater flexibility. The ATF750C-10SU-T specifically denotes the 10 ns speed grade in a 24-lead SOIC package suitable for industrial environments.

Complex Programmable Logic Devices Replacement Considerations

The ATF750C is a direct functional replacement for the ATV750(L) and ATV750B(L). When migrating, ensure that the design utilizes the full feature set of the ATF750C, including pin-keeper configuration and individual flip-flop clocking, which are not available in the legacy parts.
