NOTES:
1. For conditions shown as MIN or MAX, use the appropriate value specified under recommended operating conditions for the applicable device type.
2. Not more than one output should be shorted at a time, nor for more than 1 second.
The Terminal Count (TC) output is HIGH when CET is HIGH
and the counter is in state 15. To implement synchronous mul-
tistage counters, the TC outputs can be used with the CEP
and CET inputs in two different ways. The TC output is subject
to decoding spikes due to internal race conditions and is there-
fore not recommended for use as a clock or asynchronous
reset for flip-flops, counters, or registers.
Logic Equations:
Count Enable = CEP • CET • PE
TC = Q0 • Q1 • Q2 • Q3 • CET
