Additional Details

The ATF1508AS's propagation delays can be less than 10 ns, and the clock frequency can exceed 100 MHz, depending on the specific configuration and operating conditions. The supply voltage is typically 5V or 3.3V. The package type is often a PLCC (Plastic Leaded Chip Carrier) or TQFP (Thin Quad Flat Pack). Further details, including specific timing characteristics, power consumption, and pinout details, can be found in the device's datasheet. Due to its END-OF-LIFE status, newer CPLDs from Microchip or other manufacturers are recommended.
