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. V_DD - V_EE = 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 V_DD = 5 V
- 2 V at V_DD = 10 V
- 2.5 V at V_DD = 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 (V_DD to V_SS) to be the same as or different from the 7-segment output-signal swings (V_DD to V_EE). For example, the BCD input-signal (V_DD to V_SS) may be as small as 0 to -3 V, whereas the output-display drive-signal swing (V_DD to V_EE) may be as large as from 0 to -15 V. If V_DD to V_EE exceeds 15 V, V_DD to V_SS 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.
