SEMICONDUCTOR TECHNICAL DATA L SUFFIX CERAMIC CASE 623 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. • • • • • • P SUFFIX PLASTIC CASE 709 DW SUFFIX SOIC CASE 751E Four Operating Modes (See truth table) Input Error Detection Circuit Clock Conditioning Circuits for Slow Transition Inputs Counter Sequences on Positive Transition of Clock A Supply Voltage Range = 3.0 Vdc to 18 Vdc Capable of Driving Two Low–power TTL Loads or One Low–power Schottky TTL Load Over the Rated Temperature Range ORDERING INFORMATION MC14XXXBCP MC14XXXBCL MC14XXXBDW Plastic Ceramic SOIC TA = – 55° to 125°C for all packages.
