www.DataSheet4U.com MOTOROLA SEMICONDUCTOR TECHNICAL DATA MC14534B 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).
