Description

OPTOLOGIC™ is the first family of truly logic compatible

optically coupled logic interface gates.

The family consists of four device types offering LSTTL

to TTL and LSTTL to CMOS interfacing. Each of these

interfacing functions is available as a buffer (A = B), or

as an inverter (A = B).

The LSTTL input compatibility is provided by an input

integrated circuit, with industry standard logic levels.

This input amplifier IC switches a temperature compen-

sated current source driving a high speed 850nm

AlGaAs LED emitter. This novel integration scheme

eliminates CTR degradation over time and temperature.

The emitter is optically coupled to an integrated photode-

tector/high-gain, high-speed output amplifier IC. The

superior 15kV/µS common-mode noise rejection is

ensured through the use of an optically transparent

noise shield.

The TTL compatible output has a totem-pole with a

fan-out of 10. The CMOS compatible output has an open

collector Schottky-clamped transistor that interfaces to

any CMOS logic between 4.5 and 15 volts. The

74OL6010/11 may also by used to drive power MOSFETs

or transistors up to 15 volts.

The Optologic coupler family typically offers propagation

of delays of 60 ns and can support 15 MBaud data

communication.

The two input chips and the output chip are assembled

in a 6-pin DIP high insulation voltage plastic package.

Fairchild’s proprietary OPTOPLANAR® construction pro-

vides a withstand test voltage of 5300 VRMS (1 minute).
