DESCRIPTION
• Low input current line receiver long lines, party lines
The SFH6318 is ideal for TTL applications since the 300 %
minimum current transfer ratio with an LED current of
1.6 mA enables operation with one unit load-in and one
unit load-out with a 2.2 k pull-up resistor.
• Telephone ring detector
The SFH6319 is best suited for low power logic
applications involving CMOS and low power TTL. A 400 %
current transfer ratio with only 0.5 mA of LED current is
guaranteed from 0 °C to 70 °C.
• Low power systems - ground isolation
• Line voltage status indication - low input power
dissipation
AGENCY APPROVALS
• UL1577
• cUL
Very high current ratio together with 4000 VRMS isolation are
achieved by coupling an LED with an integrated high gain
photo detector in a SOIC-8 package. Separate pins for
the photo diode and output stage enable TTL compatible
saturation voltages with high speed operation.
Photodarlington operation is achieved by tying the VCC and
VO terminals together. Access to the base terminal allows
adjustment to the gain bandwidth.

Notes
(1) Common mode transient immunity in logic high level is the maximum tolerable (positive) dV /dt
cm
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 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)
(2) In applications where dv/dt may exceed 50 000 V/μs (such as state discharge) a series resistor, R
CC should be included to protect IC from
destructively high surge currents. The recommended value is refer to Fig. 2.
