FOD8012A 是一款半工、双向、高速逻辑门极光耦合器,支持隔离式通信,使得数字信号能够在系统之间进行通信,而无需导通接地回路或危险电压。它利用安森美半导体的专利共面封装技术 Optoplanar®, 和优化的集成电路设计,可实现最低 20 kV/μs 的共模干扰抑制 (CMR) 等级。此高速逻辑门极光耦合器与布置为双向配置的 2 个光耦合沟道进行高度集成,采用紧凑的 8 引脚小型封装。每个光耦合器沟道都包含一个高速 AlGaAs LED,由与 CMOS 检测集成电路耦合的 CMOS 缓冲集成电路驱动。该检测集成电路包含一个集成光电二极管、一个高速互阻抗放大器和一个带有输出驱动器的电压比较器。该 CMOS 技术与高能效 LED 进行耦合,实现了低能耗以及极高速(60ns 传播延迟、15ns 脉冲宽度失真)。
