MC14534BCL-MC14534BCP
5 Cascaded BCD Counters
-The MC14534B is composed of five BCD ripple counters that have their
respective outputs multiplexed using an internal scanner. Outputs of each
counter are selected by the scanner and appear on four (BCD) pins.
Selection is indicated by a logic high on the appropriate digit select pin. Both
BCD and digit select outputs have three–state controls providing an
“open–circuit” when these controls are high and allowing multiplexing.
Cascading may be accomplished by using the carry–out pin. The counters
and scanner can be independently reset by applying a high to the counter
master reset (MR) and the scanner reset (SR). The MC14534B was
specifically designed for application in real time or event counters where
continual updating and multiplexed displays are used.
