Classic EPLD Family Data Sheet

Notes to tables:

(1)

These values are specified in Table 3 on page 758.

(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)

(6)

Measured with a device programmed as a 16-bit counter.

(7)

Sample-tested only. This parameter is a guideline based on extensive device characterization. This parameter

applies for both global and array clocking.
