HCPL-0720/7720 and HCPL-0721/7721
40 ns Propagation Delay,
CMOS Optocoupler
Data Sheet
Description
Available in either an 8-pin DIP or
SO-8 package style respectively, the
HCPL-772X or HCPL-072X
optocouplers utilize the latest
CMOS IC technology to achieve
outstanding performance with very
low power consumption. The
HCPL-772X/072X require only two
bypass capacitors for complete
CMOS compatability.
Basic building blocks of the
HCPL-772X/072X are a CMOS
LED driver IC, a high speed LED
and a CMOS detector IC. A CMOS
logic input signal controls the
LED driver IC which supplies
current to the LED. The detector
IC incorporates an integrated
photodiode, a high-speed
transimpedance amplifier, and a
voltage comparator with an
output driver.

* Pin 3 is the anode of the internal LED and must be left unconnected for
guaranteed data sheet performance. Pin 7 is not connected internally.
**A 0.1 µF bypass capacitor must be connected between pins 1 and 4, and
5 and 8.

DIN IEC 112/VDE 0303 Part 1
Material Group (DIN VDE 0110, 1/89,
Table 1)
All Agilent data sheets report the
creepage and clearance inherent
to the optocoupler component
itself. These dimensions are
needed as a starting point for the
equipment designer when
determining the circuit insulation
requirements. However, once
mounted on a printed circuit
board, minimum creepage and
clearance requirements must be
met as specified for individual
equipment standards. For
creepage, the shortest distance
path along the surface of a
printed circuit board between the
solder fillets of the input and
output leads must be considered.
There are recommended
techniques such as grooves and
ribs which may be used on a
printed circuit board to achieve
desired creepage and clearances.
Creepage and clearance distances
will also change depending on
factors such as pollution degree
and insulation level.
