八路收发器,CMOS,低电压

Favorite

概览

MC74LCX245 是一款高性能非反向八路收发器,运行电压为 2.0 V 到 5.5V。高阻抗 TTL 兼容输入显著减少了输入驱动器的电流负载,而 TTL 兼容输出则提高了开关噪音性能。5.5V 的 VI 规格使得 MC74LCX245 输入能够基于 5V 器件进行安全驱动。MC74LCX245 适用于内存地址驱动和所有 TTL 级总线导向收发器应用。电流驱动能力在 A 和 B 端口均为 24mA。发射/接收 (T/Rbar) 输入决定了数据流经双向收发器的方向。发射(有效高电平)让数据能够从 A 端口流向 B 端口;接收(有效低电平)则让数据能够从 B 端口流向 A 端口。输出启用输入如果为高电平则会将 A 端口和 B 端口置于高电平 Z 状态,从而将两者禁用。
