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. MAXIMUM RATINGS* (Voltages Referenced to VSS)

** The formulas given are for the typical characteristics only at 25_C. #Data labelled "Typ" is not to be used for design purposes but is intended as an indication of the IC's potential performance.
To calculate total supply current at loads other than 50 pF:
IT(CL) = IT(50 pF) + (CL - 50) Vfk where: IT is in A (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.

APPLICATIONS INFORMATION
Expanded decoding can be performed by using the MC14028B and other CMOS Integrated Circuits. The circuit in Figure 2 converts any 4-bit code to a decimal or hexadecimal code. The accompanying table shows the input binary combinations, the associated "output numbers" that go "high" when selected, and the "redefined output numbers" needed for the proper code. For example: For the combination DCBA = 0111 the output number 7 is redefined for the 4-bit binary, 4-bit gray, excess-3, or excess-3 gray codes as 7, 5, 4, or 2, respectively. Figure 3 shows a 6-bit binary 1-of-64 decoder using nine MC14028B circuits and two MC14069UB inverters. The MC14028B can be used in decimal digit displays, such as, neon readouts or incandescent projection indicators as shown in Figure 4.
