10 / 15 page TYPICAL APLLICATIONS (continued) Figure 14 : Typical 3 1/2 – Digit–crystal Display : (VDD =+5V, VSS = 0V, VEE = – 10V, DFN = 30 Hz square). In addition to the letters L, H, P, and A, five other let- ters can be displayed through the use of simple logic circuits preceding and following the HCC/HCF4055B or HCC/HCF4056B devices. Fig. 13 is an example of a circuit that converts an ”H” display, (code 1011) to an ”F” display. One condition that must be met is that VEE =VSS.If VEE ≠ VSS,the HCC/HCF4054B must be used to level shift in the appropriate places. In a similar manner the letters C, E, J,and U can be displayed. These circuits can also be used to drive LED displays provided the exclu- sive-OR gates have sufficient output-current drive. The letters B, D, G, I, O, and S may be represented by the codes for numbers 8, 0, 6, 1, 0, and 5, respec- tively, when there is preknowledge that only letters are to be displayed.
