描述 Description

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.)
