MOTOROLA SEMICONDUCTOR TECHNICAL DATA MC14547B High Current BCD-to-Seven Segment Decoder/Driver The MC14547 BCD­to­seven segment decoder/driver is constructed with complementary MOS (CMOS) enhancement mode devices and NPN bipolar output drivers in a single monolithic structure. The circuit provides the functions of an 8421 BCD­to­seven segment decoder with high output drive capability. Blanking (BI), can be used to turn off or pulse modulate the brightness of the display. The MC14547 can drive seven­segment light­emitting diodes (LED), incandescent, fluorescent or gas discharge readouts either directly or indirectly. Applications include instrument (e.g., counter, DVM, etc.) display driver, computer/calculator display driver, cockpit display driver, and various clock, watch, and timer uses. · · · · · · · · High Current Sourcing Outputs (Up to 65 mA) Low Logic Circuit Power Dissipation Supply Voltage Range = + 3.0 V to + 18 V Blanking Input Readout Blanking on All Illegal Combinations Lamp Intensity Modulation Capability Multiplexing Capability Capable of Driving Two Low­Power TTL Loads, One Low­Power Schottky TTL Load or Two HTL Loads over the Rated Temperature Range · Use MC14511B for Applications Requiring Data Latches MAXIMUM RATINGS* (Voltages referenced to VSS, Pin 8) Rating Symbol VDD Vin TA Tstg IOHmax PD DC Supply Voltage MC14XXXBCP MC14XXXBCL MC14XXXBDW L SUFFIX CERAMIC CASE 620 P SUFFIX PLASTIC CASE 648 DW SUFFIX SOIC CASE 751G ORDERING INFORMATION Plastic Ceramic SOIC TA = ­ 55° to 125°C for all packages.
