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.
