BCD-to-Decimal Decoder

Favorite

Overview

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.
  • Pb-Free Packages are Available
