Description
The HCC240 and HCC242 are optically
coupled isolators, consisting of a gallium
aluminum arsenide LED and a silicon
phototransistor mounted and coupled in
a miniature surface mount hermetic
leadless chip carrier. The HCC240 and
HCC242 are identical except for the DC
current transfer ratio. Electrical
parameters are similar to the JEDEC
registered 4N22A and 4N24A. These
solid state couplers are ideal for designs
where board space and device weight
are important design considerations.
Typical screening and lot acceptance
tests are provided on page 13-4. The
burn-in condition is V

= 20-50 mA (adjusted to achieve

device.
