DESCRIPTION
The VOM452T and VOM453T, 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 VOM452T and VOM453T 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 VOM452T and VOM453T are packaged in industry
standard SOP-5 packages and are suitable for surface
mounting.
