CD4028BM CD4028BC BCD-to-Decimal Decoder February 1988 CD4028BM CD4028BC BCD-to-Decimal Decoder General Description The CD4028BM CD4028BC is a BCD-to-decimal or binaryto-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 Features Y Y Y Y Y Y Wide supply voltage range 3 0V to 15V High noise immunity 0 45 VDD (typ ) Low power TTL fan out of 2 driving 74L compatibility or 1 driving 74LS Low power Glitch free outputs ‘‘Positive logic’’ on inputs and outputs Applications Y Y Y Code conversion Address decoding Indicator-tube decoder Logic and Connection Diagrams
