MC14028B

MOTOROLA SEMICONDUCTOR TECHNICAL DATA MC14028B BCD-To-Decimal Decoder Binary-To-Octal Decoder The MC14028B 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–16), etc., can be achieved by using other MC14028B devices. The part is useful for code conversion, address decoding, memory selection control, demultiplexing, or readout decoding. Diode Protection on All Inputs Supply Voltage Range = 3.0 Vdc to 18 Vdc 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 Similar to CD4028B.
