CD4028BM CD4028BC BCD-to-Decimal Decoder
General Description
The CD4028BM 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 V
DD
and V
SS
