CD4034 8-Stage Bidirectional Bus Register
Package CDIP-24, SOIC-24 Series CD4000 (CMOS) Status Active (10-Dec-2020)
CD4034 overview
CD4034 belongs to 4000 Series CMOS Logic Family of Integrated Circuits (IC's) constructed with N- and P-channel enhancement mode transistors. CD4034 has 8-Stage Bidirectional Bus Register
CD4034 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.
