Vishay Semiconductors VOM452T / VOM453T
High Speed Optocouplers

Vishay Semiconductors VOM452T / VOM453T High Speed Optocouplers each consist of a GaAlAs infrared emitting diode, optically coupled with an integrated photo detector and a high speed transistor. The photo detector is junction isolated from the transistor to reduce miller capacitance effects. Vishay Semiconductors VOM452T / VOM453T High Speed Optocouplers have open collector output and very high common mode transient immunity. The open collector output function allows circuit designers to adjust the load conditions when interfacing with different logic systems such as TTL, CMOS, etc. VOM452T / 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.
