1 / 7 page MOTOROLA CMOS LOGIC DATA 1 MC14547B High Current BCD-to-Seven Segment Decoder/Driver The MC14547 BCD–to–seven 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 BCD–to–seven 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 seven–segment light–emitting 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 Low–Power TTL Loads, One Low–Power 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 Value Unit DC Supply Voltage VDD – 0.5 to + 18 V Input Voltage, All Inputs Vin – 0.5 to VDD + 0.5 V Operating Temperature Range TA – 55 to + 125 _C Storage Temperature Range Tstg – 65 to + 150 _C Maximum Continuous Output Drive Current (Source) per Output IOHmax 65 mA Maximum Continuous Power Dissipation PD 1200* mW * Maximum Ratings are those values beyond which damage to the device may occur. * See Power Derating Curve Figure 1. This device contains circuitry to protect the inputs against damage due to high static voltages or electric fields; however, it is advised that normal precautions be taken to avoid application of any voltage higher than maximum rated voltages to this high-impedance circuit. A destruc- tive high current mode may occur if Vin and Vout is not constrained to the range VSS ≤ (Vin or Vout) ≤ VDD. Due to the sourcing capability of this circuit, damage can occur to the device if VDD is applied, and the outputs are shorted to VSS and are at a logical 1 (See Maximum Ratings). Unused inputs must always be tied to an appropriate logic voltage level (e.g., either VSS or VDD).
