ambient temperature range

• 1500 VDC electrical isolation

• Small footprint for a hybrid device

• High-speed, 1 Mbps typical

• Open collector output

• High reliability and rugged construction

• Similar to 6N135/136, 4N55 type optocouplers

• Radiation tolerant

• Custom packages are available (contact Isolink)

Description

The OLI300 is suitable for interfacing Transistor-to-Transistor

Logic (TTL) to Low Power Schottky Transistor-Transistor Logic

(LSTTL), TTL, or Complementary Metal Oxide Semiconductor

(CMOS), as well as wide bandwidth analog applications.

Each OLI300 has an LED and an integrated photodiode transistor

detector mounted and coupled in a miniature custom ceramic

package that provides 1500 VDC of electrical isolation between the

input and output. The integrated photodiode transistor improves

the switching speed by orders of magnitude as compared to

standard phototransistors by reducing the base-to-collector

capacitance.

Device mounting is achieved by a standard hybrid assembly with

non-conductive epoxies. Gold or aluminum wire bonding can be

used to make electrical connections for maximum placement

flexibility.

Note: Certain cleaning processes may be harmful to this device.
