Functional description
[1]
H = HIGH voltage level steady state
h = HIGH voltage level one set-up time prior to the LOW-to-HIGH clock transition
L = LOW voltage level steady state
l = LOW voltage level one set-up time prior to the LOW-to-HIGH clock transition
qn = Lower case letters indicate state of referenced output prior to the LOW-to-HIGH clock transition
X = don’t care
= LOW-to-HIGH clock transition
* = The TC is LOW when CET is LOW and the counter is at terminal count
Terminal count up is (HHHH) and terminal count down is (LLLL)
