The NTE4055B (display frequency output) and NTE4056B (strobed−latch function) are single−digit BCD−to−7−segment decoder/driver circuits in a 16−Lead DIP-type package that provides 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 small as 0 to −3V, whereas the output display drive signal swing (VDD to VEE) may be as large as from 0 to −15V. If VDD to VEE exceeds 15V, VDD to VSS should be at least 4V (0 to −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 NTE4055B provides a level−shifted high−amplitude DF output which is required for driving the common electrode in liquid−crystal displays. The NTE4056B provides a strobed latch function at the BCD inputs. Encoding of all input combinations on the NTE4055B and NTE4056B provides displays of 0 to 9 as well as L, P, H, A, − and a blank position.

Summary

The NTE4055B (display frequency output) and NTE4056B (strobed−latch function) are single−digit BCD−to−7−segment decoder/driver circuits in a 16−Lead DIP-type package that provides level−shifting functions on the chip.

For example, the BCD input signal swings (VDD to VSS) may be as small as 0 to −3V, whereas the output display drive signal swing (VDD to VEE) may be as large as from 0 to −15V. If VDD to VEE exceeds 15V, VDD to VSS should be at least 4V (0 to −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.
