HCPL-0720, HCPL-7720, HCPL-0721,
and HCPL-7721
40-ns Propagation Delay, CMOS Optocoupler
Description
Available in either an 8-pin DIP or SO-8 package style
respectively, the Broadcom
®
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.

Conditions

Measured from input terminals to output terminals,

Insulation thickness between emitter and detector;
also known as distance through insulation.
DIN IEC 112/VDE 0303 Part 1.
Material Group (DIN VDE 0110, 1/89, Table 1).
All Broadcom 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.
