Description

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), MC14547 BCD 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 of MC14547 BCD include instrument (e.g., counter, DVM, etc.) display driver, computer/calculator display driver, cockpit display driver, and various clock, watch, and timer uses.
