DESCRIPTION The HCC4054B, HCC4055B and HCC4056B (extended temperature range) and the HCF4054B, HCF4055B and HCF4056B (intermediate temperature range) are monolithic integrated circuits available in 16-lead dual in-line plastic or ceramic package and plastic micro package. The HCC/HCF4055B and HCC/HCF4056B types are single-digit BCD-to-7-segment decoder/driver circuits that provide level-shifting functions on the chip. This feature permits the BCD input-signal swings (VDD to VSS) to be the same as

or different from the 7-segment output-signal swings (VDD to VEE). For example, the BCD input-signal swings (VDD to VSS) may be as low as 0 to ­ 3V, whereas the output-display drive-signal swing (VDD to VEE) may be from 0 to ­ 5V. If VDD to VEE exceeds 15V, VDD to VSS should be at least 4V. The 7-segment outputs are controlled by the DISPLAY-FREQUENCY (DF) input which causes the selected segment outputs to be low, high, or a square-wave output (for liquid-crystal displays). When the DF input is low the output segments will be high when selected by the BCD inputs. When the DF input is high, the output segments will be low when selected by the BCD inputs. When a square-wave is present at the DF input, the selected segments will have a square-wave output that is 180° out of phase with the DF input. Those segments which are not selected will have a square-wave output that is in phase with the input. DF square-wave repetition rates for liquid-crystal displays usually range from 30Hz (well above flicker rate) to 200Hz (well below the upper limit of the liquid-crystal frequency response). The HCC/HCF4055B provides a levelshifted high-amplitude DF output which is required for driving the common electrode in liquid-crystal displays. The HCC/HCF4056B provides a strobedlatch function at the BCD inputs. Decoding of all input combinations on the HCC/HCF4055B and HCC/HCF4056B provides displays of 0 to 9 as well

as L, P, H, A,­ , and a blank position. (see typical application for other letters). The HCC/HCF4054B provides level shifting similar to the HCC/HCF4055B and HCC/HCF4056B independently strobed latches, and common DF control on 4 signal lines. The HCC/HCF4054B is intended to provide drive-signal compatibility with the HCC/HCF4055B and HCC/HCF4056B 7-segment decoder types for the decimal point, colon, polarity, and similar display lines. A level-shifted high-amplitude DF output can be obtained from any HCC/HCF4054B output line by connecting the corresponding input and strobe lines to a low and high level, respectively. The HCC/HCF4054B may also be utilized for logic-level "up conversion" or "down conversion". Forexample, input-signal swings (VDD to VSS) from + 5 to 0V can be converted to output-signal swings (VDD to VEE) of + 5 to ­ 5V. The level-shifted function on all three types permits the use of different input-and outputsignal swings. The input swings from a low level of VSS to a high level of VDD while the output swings PIN CONNECTIONS
4054B 4055B 4056B

from a low level of VEE to the same high level of VDD. Thus, the input and output swings can be selected independently of each other over a 3-to-18V range. VSS may be connected to VEE when no level-shift function is required. For the HCC/HCF 4054B and HCC/HCF 4056B, data are transferred from input to output by placing a high voltage level at the strobe input. A low voltage level at the strobe input latches the data input and the corresponding output segments remain selected (or non-selected) while the strobe is low. Whenever the level-shifting function is required, the HCC/HCF4055B can be used by itself to drive a liquid-crystal display (fig. 10 and fig. 12). The HCC/HCF4056B, however, must be used together with a HCC/HCF4054B to provide the common DF output (fig. 14). The capability of extending the voltage swing on the negative end (this voltage cannot be extended on the positive end) can be used to advantage in the set-up of fig. 11. Fig. 9 is common to all three types.

In addition to the letters L, H, P, and A, five other letters 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 exclusive-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, respectively, when there is preknowledge that only letters are to be displayed.
