CD4028BPWR

CD4028B types are BCD-todecimal 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 inputs, 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 = "U". High drive capability is provided at all outputs to enhance dc and dynamic performance in high fan-out applications.

Key features

• BCD-to-decimal decoding or binary-to-octal decoding

• Standardized, symmetrical output characteristics
• 100% tested for quiescent current at μz0V
• Maximum input current of 1μA at μV over full package-temperature range; 100 nA at 18 V and 25°C
• Noise margin (over full package-temperature range): 1V at VDD = 5V, 2V at VDD = 10V, 2.5V at VDD = 15V
• 5-V, 10-V, and 15-V parametric ratings
