... MOTOROLA SEMICONDUCTOR TECHNICAL DATA 3-Digit BCD Counter The MC14553B 3–digit BCD counter consists of 3 negative edge triggered BCD counters that are cascaded synchronously. A quad latch at the output of each counter permits storage of any given count. The information is then time division multiplexed, providing one BCD number or digit at a time. Digit select outputs provide display control. All outputs are TTL compatible. An on– ...

... The MC14553B three–digit counter, shown in Figure 3, consists of three negative edge–triggered BCD counters which are cascaded in a synchronous fashion. A quad latch at the output of each of the three BCD counters permits stor- age of any given count. The three sets of BCD outputs (active high), after going through the latches, are time divi- sion multiplexed, providing one BCD number or digit at a time ...
