VOM453T

The VOM453T is a 1-channel 5-pin analogue High Speed Coupler consists of a GaAlAs infrared emitting diode, optically coupled with an integrated photodetector and a high speed transistor. The photodetector is junction isolated from the transistor to reduce miller capacitance effects. The open collector output function allows circuit designers to adjust the load conditions when interfacing with different logic systems such as TTL and CMOS. Because the VOM452 has a Faraday shield on the detector chip, it can also reject and minimize high input to output common-mode transient voltages. There is no base connection, further reducing the potential electrical noise entering the package. This an ideal solution for industrial communication bus isolation, as well as isolated drive circuit applications such as IPM (intelligent power module) drivers.
