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:

count enable = CEP • CET • PE

count up: TC = Q3 • Q2 • Q1 • Q0 • CET • U ⁄ D

count down: TC = Q3 • Q2 • Q1 • Q0 • CET • U ⁄ D
