Description

The CD4028BM/CD4028BC is a BCD-to-decimal or binary-to-octal decoder consisting of 4 inputs, decoding logic gates, and 10 output buffers. A BCD code applied to the 4inputs, A, B, C, and D, results in a high level at the selected1-of-10 decimal decoded outputs. Similarly, a 3-bit binary code applied to inputs A, B, and C is decoded in octal at outputs 0–7. A high level signal at the D input inhibits octal decoding and causes outputs 0–7 to go low.

Features:

  1. Wide supply voltage range3.0V to 15V
  2. High noise immunity0.45 VDD(typ.)
  3. Low power TTL compatibility: fan out of 2 driving 74Lor 1 driving 74LS
  4. Low power
  5. Glitch free outputs
  6. ‘‘Positive logic’’ on inputs and outputs
