CD74HC4543概述

用于 LCD 的高速 CMOS 逻辑 BCD 至 7 段锁存器/解码器/驱动器

The 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.
