High Speed Optocoupler, 100 kBd, Low Input Current, High Gain

DESCRIPTION

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.

adjustment to the gain bandwidth.

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

Ω pull-up resistor.

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.

Caution:

Due to the small geometries of this device, it should be

handled with electrostatic discharge (ESD) precautions.

Proper grounding would prevent damage further and / or

degradation which may be induced by ESD.

FEATURES

• High current transfer ratio, 300 %

• Low input current, 0.5 mA

• High output current, 60 mA

• Adjustable bandwidth access to base

• Material categorization: for definitions of

APPLICATIONS
