概览

MM74HC245A 3 态双向缓冲器利用先进的硅门极 CMOS 技术，适用于数据总线之间的双向异步通信。它具有高驱动电流输出，即使驱动较大的总线电容也能实现高速运行。该电路具有通常与 CMOS 电路相关的低功耗和高抗干扰度，而速度却可与低功率肖特基 TTL 电路相媲美。此器件具有有效低电平启用输入 G# 和方向控制输入 DIR。当 DIR 为高电平 时，数据从 A 输入流向 B 输出。当 DIR 为低电平时，数据从 B 输入流向 A 输出。MM74HC245A 将真实数据从一个总线传送到另一个总线。此器件可以驱动最多 15 个 LS-TTL 负载，并且没有施密特触发器输入。通过将二极管箝位到 VCC 和接地，可防止所有输入因静电放电而受损。
