29 / 42 page ![]() Altera Corporation 773 Classic EPLD Family Data Sheet Notes to tables: (1) These values are specified in Table 15 on page 770. (2) See Application Note 78 (Understanding MAX 5000 & Classic Timing) in this data book for more information on Classic timing parameters. (3) The non-Turbo adder must be added to this parameter when the Turbo Bit option is off. (4) Sample-tested only for an output change of 500 mV. (5) The fMAX values represent the highest frequency for pipelined data. (6) Measured with a device programmed as a 24-bit counter. (7) Sample-tested only. This parameter is a guideline based on extensive device characterization and applies for both global and array clocking. Table 20.
