Description

These dual channel optocoup lers contain a pair of light emitting diodes and integrated photo-detec tors with electrical insulation between input and output. Separate connection for the photodiode bias and output transistor collectors increase the speed up to a hundred times that of a conventional phototransistor coupler by reducing the base-collector capacitance.

These dual channel optocouplers are available in an 8 Pin DIP and in an industry standard SO-8 package. The following is a cross reference table listing the 8 Pin DIP part number and the electrically equivalent SO-8 part number.

Applications

• Line receivers – high common mode transient immunity (>1000 V/μs) and low input-output capacitance (0.6 pF)

• High speed logic ground isolation – TTL/TTL, TTL/LTTL, TTL/CMOS, TTL/LSTTL

• Replace pulse transformers – save board space and weight

• Analog signal ground isolation – integrated photon detector provides improved linearity over phototran sistor type

• Polarity sensing

• Isolated analog amplifer – dual channel packaging enhances thermal tracking
