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.

#Data labelled “Typ” is not to be used for design purposes but is intended as an indication of the IC’s potential performance.
** The formulas given are for the typical characteristics only at 25_C.
†To calculate total supply current at loads other than 50 pF:
IT(CL) = IT(50 pF) + (CL – 50) Vfk
where: IT is in µA (per package), CL in pF, V = (VDD – VSS) in volts, f in kHz is input frequency, and k = 0.001.
This device contains protection circuitry to guard against damage
due to high static voltages or electric fields. However, precautions must
be taken to avoid applications of any voltage higher than maximum rated
voltages to this high-impedance circuit. For proper operation, Vin and
Vout should be constrained to the range VSS ≤ (Vin or Vout) ≤ VDD.
Unused inputs must always be tied to an appropriate logic voltage
level (e.g., either VSS or VDD). Unused outputs must be left open.
