H = HIGH Voltage Level
L = LOW Voltage Level
h = HIGH voltage level one setup time prior to the LOW-to-HIGH clock transition
l = LOW voltage level one setup time prior to the LOW-to-HIGH clock transition
X = Immaterial
q = Lower case letter indicate the state of the referenced output prior to the LOW-to-HIGH clock transition
= LOW-to-HIGH clock transition
NOTES:
1. The TC output is HIGH when TE is HIGH and the counter is at terminal count (HLLH for 162 and HHHH for 163)
2. The HIGH-to-LOW transition of PE or TE on the 54/74163 and 54/74160 should only occur while CP is high for conventional operation
3. The LOW-to-HIGH transition of SPE or MR on the 54/74163 should only occur while CP is high for conventional operation
