UCD4028B Overview
Description
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-sixteen), etc., can be achieved by using other UTC UCD4028B devices.
Key Features
- * Positive Logic Design * Low Outputs on All Illegal Input Combinations
