Description: CD4028 Decimal Decoder IC CD 4028 CMOS BCD
CD4028 CD4028BE CD-4028 4028 DIP-16 Pin Leads Dual In Package BCD IC Breadboard Friendly IC
The CD4028B 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 4 inputs, A, B, C, and D, results in a high level at the selected 1-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. All inputs are protected against static discharge damage by diode clamps to VDD and VSS.
