The following model demonstrates the use of IBIS multistage driver
|
schedules to describe an inverting and non-inverting model
|
with pulsed turn-off of the pullup transistor in an output
|
stage. In this example, during pullup cycles the pullup driver
|
is turned on at time=0 and then turned off at time=10ns. The pulldown
|
driver is always on during the pulldown part of the cycle.
