Description

   OPTOLOGIC™ of the 74OL6011 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 of the 74OL6011 is provided by an input integrated circuit, with industry standard logic levels. This input amplifier IC switches a temperature compensated current source driving a high speed 850 nm AlGaAs LED emitter. This novel integration scheme eliminates CTR degradation over time and temperature.
 
   The emitter of the 74OL6011 is optically coupled to an integrated photodetector/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 Schottkyclamped 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. It provides a withstand test voltage of 5300 VRMS (1 minute).
