CD4539-Dual 4-input multiplexer


CD4539 belongs to the 4000 Series CMOS Logic Family of Integrated Circuits (IC’s) constructed with N- and P-channel enhancement mode transistors. CD4539 has a Dual 4-input multiplexer

CD4539 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.

CD4539 Features

  • High-Voltage Types (20V Rating)

  • Buffered Inputs and Outputs
  • Standard Symmetrical Output Characteristics
  • 100% Tested for Maximum Quiescent Current at 20V
  • 5V, 10V, and 15V Parametric Ratings
