The BCD to 7 Segments Decoder is used exclusively for the drive the display of decimal digits; therefore, it is usually called Decoder Driver.
BCD to 7 Segments Decoders are the TTL the 74(LS)47 which drives the common anode displays and the 74(LS)48 which drives the common cathode displays. CMOS technology decoder is the CD4511 which drives the common cathode display with latch ability.
