EP220 & EP224 Classic EPLDs

AC Operating Conditions: -7 & -10 Speed Grades

Note (1)

Notes to tables:

(1)

Operating conditions: VCC = 5 V ± 5%, TA = 0° C to 70° C for commercial use.

(2)

Measured with three I/O outputs switching.

(3)

The tPZX and tPXZ parameters are measured at ± 0.5 V from steady-state voltage that is driven by the specified

output load. The tPXZ parameter is measured with CL = 5 pF and with all eight outputs switching.
