High Speed Optocoupler, 1 MBd, Transistor Output
SFH6315T, SFH6316T, SFH6343T
Vishay Semiconductors
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.

Note
• Common mode transient immunity in a logic high level is the maximum tolerable (positive) dVCM/dt on the leading edge of the common mode
pulse (VCM) to assure that the output will remain in a logic high state (i.e., VO > 2 V). Common mode transient immunity in a logic low level
the maximum tolerable (negative) dVCM/dt on the trailing edge of the common mode pulse signal (VCM to assure that the output will remain
in logic low state, i.e., VO > 0.8 V).
The 1.9 kΩ load represents 1 TTL unit load of 1.6 mA and the 5.6 kΩ pull-up resistor.
The 4.1 kΩ load represents 1 LSTTL unit load of 0.36 mA and the 6.1 kΩ pull-up resistor.

Note
• As per IEC 60747-5-5, §7.4.3.8.1, this optocoupler is suitable for “safe electrical insulation” only within the safety ratings. Compliance with
the safety ratings shall be ensured by means of protective circuits.
