Table 2 shows a number of codes and the decimal or hexadecimal number in these codes which must be applied to the input terminals of the CD4028BMS to select a particular output. For example: in order to get a high on output number 8 the input must be either an 8 expressed in 4-bit Binary code, a 15 expressed in 4-Bit Gray code, or a 5 expressed in Excess-3 code. TABLE 2.
