BCD-TO-DECIMAL DECODER
General Description
The CD4028BM 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.

Note 2:
"Absolute Maximum Ratings" are those values beyond which the safety of the device
cannot be guaranteed; they are not meant to imply that the devices should be operated
at these limits. The table of "Recommended Operating Conditions" and "Electrical
Characteristics" provides conditions for actual device operation.
Vss = 0V unless otherwise specified.
