  • BCD-to-decimal decoding or binary-to-octal decoding, High decoded output drive capability
  • "Positive logic" inputs and outputs……decoded outputs go high on selection, Medium-speed operation… tPHL, tPLH = 80 ns (typ.) @ VDD = 10 V
  • Standardized, symmetrical output characteristics, 100% tested for quiescent current at 20 V, 5-V, 10-V, and 15-V parametric ratings
  • Maximum input current of 1 µA at 18 V over full package-temperature range; 100 nA at 18 V and 25°C, Meets all requirements of JEDEC Tentative Standard No. 13B, "Standard Specifications for Description of ’B’ Series CMOS Devices"
  • Noise margin (full package-temperature range) = 1 V at VDD = 5 V, 2 V at VDD = 10 V, 2.5 V at VDD = 15 V, Applications: Code conversion Indicator-tube decoder Address decoding-memory selection control


The CD4028 are BCD-to-decimal or binary-to-octal decoders consisting of buffering on all 4 inputs, decoding-logic gates, and 10 output buffers. A BCD code applied to the four input, A to D, results in a high level at the selected one of 10 decimal decoded outputs. Similarly, a 3-bit binary code applied to inputs A through C is decoded in octal code at output 0 to 7 if D = "0". High drive capability is provided at all outputs to enhance dc and dynamic performance in high fan-out applications.
