UCD4028B Datasheet - UTC

UCD4028B BCD-TO-DECIMAL DECODER / BINARY-TO-OCTAL DECODER

The UTC UCD4028B decoder is constructed so that an 8421 BCD code on the four inputs provides a decimal (one-of-ten) decoded output, while a 3-bit binary input provides a decoded octal (one-of-eight) code output with D forced to a logic “0”. Expanded decoding such as binary-to-hexadecimal (one-of-six.
