CD4555 Dual Binary 1 of 4 Decoder Inverter
Package DIP Series CD4000 (CMOS)
CD4555 overview
CD4555 belongs to 4000 Series CMOS Logic Family of Integrated Circuits (IC's) constructed with N- and P-channel enhancement mode transistors. CD4555 has Dual Binary 1 of 4 Decoder Inverter
CD4555 has a supply voltage range of 5V to 20V, which is much higher than any contemporary logic family. It has buffered output which improves transfer characteristics by providing very high gain. All inputs are protected against static discharge with diodes to VDD and VSS.
