VOM452 - Analog High-Speed Coupler

Datasheet Summary

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.

Features

  • Surface mountable.
  • Industry standard SOP-5 footprint.
  • Compatible with infrared vapor phase reflow and wave soldering processes.
  • Isolation test voltage, 3750 VRMS.
  • Very high common mode transient immunity: 15 000 V/μs at VCM = 1500 V guaranteed (VOM453).
  • High speed: 1 MBd.
  • TTL compatible.
  • Open collector output.
  • Material categorization: for definitions of compliance please see www. vishay. com/doc?99912.

www.vishay.com VOM452, VOM453 Vishay Semiconductors Analog High Speed Coupler, High Noise Immunity, 1 MBd, SOP-5 Package A1 C3 6 VCC 5C 4E 20409-1 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.
