The CD4056BE from RCA is a single-digit BCD-to-7-segment decoder/driver circuit designed for use with CMOS circuits and liquid-crystal displays (LCDs). This component provides ultra-low-power display operation and features an equivalent AC output drive for LCDs, eliminating the need for an external capacitor. It supports voltage doubling across the display, enabling effective drive voltages up to 36 V p-p when VDD - VEE is 18 V.
The device includes on-chip logic-level conversion, allowing BCD input signal swings to differ from the 7-segment output signal swings. It can decode all input combinations, including 0-9, L, H, P, A, -, and blank positions. The strobed-latch function is controlled by the DISPLAY-FREQUENCY (DF) input, which determines whether the selected segment outputs are low, high, or a square-wave output suitable for LCDs.
With an operating temperature range of -55 to 125°C, the CD4056BE is suitable for various applications. It is packaged in a 16-pin PDIP (N) through-hole configuration and comes in a standard package quantity of 25 units per tube. Key electrical characteristics include a maximum input current of 1 μA at 18V over the full temperature range and noise margins of up to 2.5V at 15V.
Applications for the CD4056BE include general-purpose displays, calculators, meters, wall and table clocks, industrial control panels, portable lab instruments, panel meters, auto dashboard displays, and appliance control panels.
