DESCRIPTION
The SFH6315/16/43, high speed optocouplers, each
consists of a GaAlAs infrared emitting diode, optically
coupled with an integrated photodetector and a high
speed transistor. The photodetector 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 SFH6343 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 SFH6315/16/43 are packaged in industry standard
SOIC-8 packages and are suitable for surface mounting.

Notes
1.
Current transfer ratio in percent equals the ratio of output collector current (IO) to the forward LED input current (IF) times 100.
2.
Device considered a two-terminal device: pins 1, 2, 3, and 4 shorted together and pins 5, 6, 7, and 8 shorted together.
3.
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>2.0 V). Common mode transient immunity in
a Logic Low level is 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 a Logic Low state (i.e., VO<0.8 V).
4.
The 1.9 KΩ load represents 1 TTL unit load of 1.6 mA and the 5.6 kΩ pull-up resistor.
5.
The 4.1 KΩ load represents 1 LSTTL unit load of 0.36 mA and the 6.1 kΩ pull-up resistor.
6.
A 0.1 µf bypass capacitor connected between pins 5 and 8 is recommended.
