Description

Features

The OLI 249 is designed especially for hybrid

application requiring optical isolation with high current

transfer ratio and low saturation Vce. Each OLI 249

consists of a light emitting diode and a NPN silicon

phototransistor mounted and coupled in a miniature

custom ceramic package. The very low input current

makes the OLI 249 well suited for direct CMOS to

LSTTL / TTL interfaces. Electrical parameters are

similar to the JEDEC registered 4N49 optocoupler

but with much better CTR degradation characteristics

due to radiation exposure.

♦ Current transfer ratio guaranteed over

-55°C to +100°C ambient temp. range

♦ 1500 Vdc electrical isolation

♦ Small foot print for hybrid device

♦ More Radiation tolerant than 4N49 ⁴

♦ High current transfer ratio at low input

current - 200% at I_F=2mA over

temperature

♦ High reliability and rugged construction

Device mounting is achieved by standard

hybrid assembly with non-conductive epoxies. Gold

or aluminum wire bonding can be used to make

electrical connections for maximum placement

flexibility .

♦ CTR comparable to darlington output

but with low saturation V_CE= 0.15v typ.

♦ Similar to 4N4X type optocouplers

♦ Custom package available

Special electrical parametric selections are

available on request.

NOTES:

1. Measured between pins 1 and 6 shorted together and pins 2,3,4,and 5 shorted together. T_A= 25°C and duration = 1 second.

2. Derate linearly at 3.0 mW / °C above 25 °C

3. Value applies for Pw ≤ 1 µS, PRR ≤ 300 pps.

4. Contact factory for more information
