Functional Description (Continued)

The Terminal Count (TC) output is HIGH when CET is HIGH

and the counter is in its maximum count state (9 for the

decade counters 15 for the binary counters) To implement

synchronous multistage counters the TC outputs can be

used with the CEP and CET inputs in two different ways

These two schemes are shown in the 9310 data sheet The

TC output is subject to decoding spikes due to internal race

conditions and is therefore not recommended for use as a

clock or asynchronous reset for flip-flops counters or regis-

ters In the decade counters of the ’LS160 ’LS162 the TC

output is fully decoded and can only be HIGH in state 9
