VOM452T Datasheet PDF - Vishay Semiconductors

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 isjunction 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.
