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 ?A 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.
