CD4511 BCD to 7-segment Latch/Decoder/Driver
Package SOIC, PDIP Series CD4000 (CMOS)
CD4511 overview
CD4511 belongs to the 4000 Series CMOS Logic Family of Integrated Circuits (IC's) constructed with N- and P-channel enhancement mode transistors. CD4511 has BCD to 7-segment Latch/Decoder/Driver
CD4511 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.
