Presettable synchronous 4-bit up/down binary counter
In order for counting to occur, both pins CEP and CET must be LOW and pin PE must be
HIGH. The pin U/D input determines the direction of the counting. The terminal count
output pin TC output is normally HIGH and goes LOW, provided that pin CET is LOW,
when a counter reaches 15 in the count up mode. The pin TC output state is not a function
of the count-enable parallel (pin CEP) input level. Since pin TC signal is derived by
decoding the flip-flop states, there exists the possibility of decoding spikes on pin TC. For
this reason the use of pin TC as a clock signal is not recommended; see the following
logic equations:
2.
Features and benefits
