The HCC4054B, HCC4055B and HCC4056B (extended temperature range) and the HCF4054B, HCF4055B and HCF4056B (intermediate temperature range) are monolithic integrated circuits available in 16-lead dual in-line plastic or ceramic package and plastic micro package. The HCC/HCF4055B and HCC/HCF4056B types are single-digit BCD-to-7-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 March 1989
