Vishay Semiconductors VOM452T/VOM453T高速光耦合器

Vishay Semiconductors /高速光耦合器包含一个GaAlAs红外发射二极管，可与集成光检器和高速晶体管光耦合。光检器是与晶体管隔离的结点，用于减少密勒电容效应。Vishay Semiconductors VOM452T/VOM453T高速光耦合器具有开路集电极输出和非常高的共模瞬态抗扰特性。开路集电极输出功能可使电路设计人员在连接不同的逻辑系统时（如TTL、CMOS 等）调整负载状态。VOM452T/VOM453T高速光耦合器在检测器芯片上配有一个法拉第屏蔽，使之能够屏蔽和最小化高输入，以输出共模瞬态电压。这些产品也没有基极连接，进一步减少进入封装件的潜在电噪声。这些光耦合器按照行业标准SOP-5进行封装，适用于表面贴装。

VOM452T and VOM453T High Speed Optocouplers have a Faraday shield on the detector chip, allowing them to reject and minimize high input to output common mode transient voltages. They also have no base connection, which further reduces the potential electrical noise entering the package. These optocouplers are packaged in industry standard SOP-5 packages and are suitable for surface mounting.
