CD4056 BCD to 7-Segment Decoder Driver

The CD4056B IC's 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 to be the same as or different from the 7-segment output-signal swings (VDD to VEE).

Features of CD4056 BCD To 7-Segment Decoder Driver:

  • Operation of liquid crystals with CMOS circuits provides ultra-low-power displays.
  • Equivalent ac output drive for liquid-crystal displays - no external capacitor required.
  • Voltage doubling across display, e.g. VDD - VEE = 18 V results in effective 36 V p-p drive across selected display segments.
  • Low- or high-output level dc drive for other types of displays.
  • On-chip logic-level conversion for different input- and output-level swings.
  • Full decoding of all input combinations: 0-9, L, H, P, A, -, and blank positions.
  • Strobed-latch function-CD4054B Series and CD4056B Series.
  • Maximum input current of 1 µA at 18 V over full package-temperature range; 100nA at 18 V and 25°C.

Applications of CD4056 BCD To 7-Segment Decoder Driver:

  • General-purpose displays.
  • Calculators and meter.
  • Wall and table clocks.
  • Industrial control panels.
  • Portable lab instruments.
  • Panel meters.
  • Auto dashboard displays.
  • Appliance control panels.
