Description
The HCPL-0708 high-speed, opto-
coupler isolates the low-voltage
logic circuit from the high-voltage
Flat-Panel Display row/column
drivers. Examples of Flat-Panel
Display technologies requiring such
high voltage technologies are Elec-
tro-Luminescence, Fluorescence,
and Plasma technologies. The opto-
coupler serves the functions of level
shifting and safety isolation.
Performance of Optocoupler
• Maximum propagation delay
time: 60 ns
• Typical pulse width distortion of
15 ns
• Common­mode transient rejec-
tion: 15,000 V/µs at 1000 V peak
Benefits
• Compact size and easy interface
compared to pulse transformers
• Low input current allowing CMOS
interface
• Low component count
