DESCRIPTION

The VOM452 and VOM453, high speed optocouplers, each

consists 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. The open

collector output function allows circuit designers to adjust

the load conditions when interfacing with different logic

systems such as TTL, CMOS, etc.

Because the VOM452 and VOM453 have 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.

The VOM452 and VOM453 are packaged in industry

standard SOP-5 packages and are suitable for surface

mounting.

This an ideal solution for Industrial communication bus

isolation, as well as isolated drive circuit applications such

as IPM (intelligent power module) drivers.
