CD4055 BCD to 7 Segment Decoder for Multiplexer Display

CD40558 and CD4056B types are single-digit BCD-to7-segment decoder/driver circuits that provide level-shifting functions on the chip. This feature permits the BCD input-signal swings (VDD to VSS) to be the same as or different from the 7-segment output-signal swings (VDD to VEE). For example, the BCD input-signal swings (VDD to VSS) may be as small as 0 to 3V, where as the output-display drive-signal swing (VDD to VEE) may be as large as from 0V to 15V. If VDD to VEE exceeds 15 V, VDD to VSS should be at least 4V (0 to 4V).
