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 dev.
* Diode Protection on All Inputs
* Supply Voltage Range = 3V to 15V
* Capable of Driving Two Low-power TTL Loads or One Low-Power Schottky TTL Load Over the Rated Temperature Range.
* Positive Logic Design
* Low Outputs on All Illegal Input Combinations
