1,285 views

CD4515 belongs to the 4000 Series CMOS Logic Family of Integrated Circuits (IC’s) constructed with N- and P-channel enhancement mode transistors. CD4515 has a 4-bit Latch/4-16 Decoder

CD4515 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.

CD4515 Features

  • Wide supply voltage range: 3.0V to 15V
  • High noise immunity: 0.45 VDD (Typ.)
  • Low power TTL: fan out of 2 compatibility: driving 74L
  • Low quiescent power dissipation: 0.025 µW/package @ 5.0 VDC
  • Single supply operation
  • Input impedance = 1012Ω typically
