The TC output is HIGH when CET is HIGH and the counter is at terminal count (HHHH)
HIGH voltage level
HIGH voltage level one set-up time prior to the LOW-to-HIGH clock transition
LOW voltage level
LOW voltage level level one set-up time prior to the LOW-to-HIGH clock transition
lower case letters indicate the state of the referenced output one set-up time prior to the LOW-to-HIGH clock transition
don’t care
LOW-to-HIGH clock transition
