DESCRIPTION
The H24B series of optically coupled isolators
consist of infrared light emitting diode and NPN
silicon photo darlington in a plastic package.
FEATURES
l 4 pin Dual-in-Line package
l High Current Transfer Ratio available
(H24B1 = 1000% min.)
l High Isolation Voltage (3.75kV
RMS
,5.3kV
PK
)
l No base connection gives improved
Common Mode Rejection
APPLICATIONS
l DC motor controllers
l Industrial systems controllers
l Signal transmission between systems of
different potentials and impedances
