Manufacturer:MT Description: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 C 3V, whereas the output-display drive-signal swing (VDD to VEE) may be from 0 to C 5V. If VDD to VEE exceeds 15V, VDD to VSS should be at least 4V. The 7-seg- ment outputs are controlled by the DISPLAY-FRE- QUENCY (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 se- lected 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 re- sponse). The HCC/HCF4055B provides a level- shifted high-amplitude DF output which is required for driving the common electrode in liquid-crystal displays. The HCC/HCF4056B provides a strobed- latch 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 |
