DESCRIPTION
The SFH6315T, SFH6316T, SFH6343T, 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 SFH6343T has 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 SFH6315T, SFH6316T, SFH6343T are packaged in
industry standard SOIC-8 packages and are suitable for
surface mounting.
• Surface mountable
• Industry standard SOIC-8 footprint
• Compatible with infrared vapor phase reflow
and wave soldering processes
• Isolation test voltage, 4000 V
RMS
• Very high common mode transient immunity:
15000 V/μs at V
CM
= 1500 V guaranteed
(SFH6343)
• High speed: 1 MBd
• TTL compatible
• Guaranteed AC and DC performance temperature:
0 °C to 70 °C
• Open collector output
• Pin compatible with agilent (HP) optocouplers
- SFH6315T - HCPL0500
- SFH6316T - HCPL0501
