CD4028 BCD to Decimal Decoder IC DIP-16 Package

CD4028 types 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.

The CD4028 Series types are supplied in 16-lead hermetic dual-in-line ceramic packages (F3A suffix), 16-lead dual-in-line plastic packages (E suffix), 16-lead small-outline packages (M, M96, MT and NSR suffixes), and 16-lead thin shrink small-outline packages (PW and PWR suffixes).

Features:-

• 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… t _PHL , t _PLH = 80 ns (typ.) @ V _DD = 10 V
• Standardized, symmetrical output characteristics
• 100% tested for quiescent current at 20 V
• Maximum input current of 1 µA at 18 V over full package-temperature range; 100 nA at 18 V and 25°C
• Noise margin (full package-temperature range) =
  1 V at V _DD = 5 V
  2 V at V _DD = 10 V
  2.5 V at V _DD = 15 V
• 5-V, 10-V, and 15-V parametric ratings
