CD4541 Oscillator/Programmable Timer
Package SOIC, PDIP Series CD4000 (CMOS)
CD4541 overview
CD4541 belongs to the 4000 Series CMOS Logic Family of Integrated Circuits (IC's) constructed with N- and P-channel enhancement mode transistors. CD4541 has an Oscillator/Programmable Timer
CD4541 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.
