The CD74HC4543 high-speed silicon-gate device is a BCD to 7-segment latch/decoder/driver designed primarily for directly driving liquid-crystal displays. It has an active-high disable input (LD), an active-high blanking input (BI) and a phase input (PH) to which a square wave is applied for liquid-crystal applications. This square wave also is applied to the backplane of the liquid-crystal display.
This device also can be used, in conjunction with current amplifying devices, for driving LEDs, incandescent, fluorescent, and gas-discharge displays. For these applications the phase input provides a means to obtain active-high or active-low segment outputs. (See the Function Table.)
