The CD74HCT4543 high-speed silicon-gate is a BCD-to-7 segment latch/decoder/driver designed primarily for directly driving liquid-crystal displays. While the latch enable (LD) is low, the latches are enabled to store the BCD inputs. When the latch enable is high, the latches are disabled, making the outputs transparent to the BCD inputs. The device has 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.
