CD4028BC
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
Wide supply voltage range 3 0V to 15V High noise immunity 0 45 VDD (typ ) Low power TTL fan out of 2 driving 74L patibility or 1 driving 74LS Low power Glitch free outputs ‘‘Positive logic’’ on inputs and outputs
