Product Information

Features

  • 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
  • DISPLAY-FREQUENCY (DF) output for liquid-crystal common-line drive signal- CD4055B Series (CD4054B Series also: see introductory text)
  • 100% tested for quiescent current at 20 V
  • Maximum input current of 1 µA at 18 V over full package-temperature range; 100nA at 18 V and 25°C
  • Noise margin (over full package-temperature range):
    • 1 V at VDD = 5 V
    • 2 V at VDD = 10 V
    • 2.5 V at VDD = 15 V
  • 5-V, 10-V, and 15-V parametric ratings
  • Applications:
    • General-purpose displays
    • Calculators and meter
    • Wall and table clocks
    • Industrial control panels

Description

CD4055B and CD4056B 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 (VDD to VSS) may be as small as 0 to -3 V, whereas the output-display drive-signal swing (VDD to VEE) may be as large as from 0 to -15 V. If VDD to VEE exceeds 15 V, 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.
