UCD4028B数据手册UTC中文资料规格书

描述 Description

The UTC UCD4028B decoder is constructed so that an 8421 BCD  ode 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”.  Expandeddecoding such as binary-to-hexadecimal (one-of-sixteen), etc., can be achieved by using other  UTC UCD4028B  devices. The part is useful for code conversion, address decoding, memory selection control, demultiplexing, or readout decoding.
