10. Set-up and Hold times are relative to the falling edge of the input clock
Parameters are guaranteed by design and characterization. Not 100% tested in production. All parameters specified with loaded outputs.
Outputs driving 50
transmission lines.
50% input duty cycle.
Outputs loaded with 30 pF each
Note:The ordering part number is formed by a combination of device number, device revision, package style, and screening as
shown below.
