CD4028BCN Datasheet PDF - Fairchild

General Description

●The CD4028BC 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.

●Features

●■Wide supply voltage range: 3.0V to 15V

●■High noise immunity: 0.45 VDD(typ.)

●■Low power TTL compatibility: fan out of 2 driving 74L or 1 driving 74LS

●■Low power

●■Glitch free outputs

●■“Positive logic” on inputs and outputs
