• Description: Radiation Hardened Synchronous Counter
• Manufacturer: Intersil Corporation

Functional Diagram
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.

1. The TC output is HIGH when TE is HIGH and the counter is at terminal count (HHHH for 161 and HLLH for 160).
2. The HIGH-to-LOW transition of PE or TE on the 54/74161 and 54/74160 should only occur while CP is high for conventional operation.
3. The LOW-to-HIGH transition of SPE on the 54/74161 and 54/74160 should only occur while CP is high for conventional operation.
