Description
These optocouplers are similar to
HP鈥檚 other high speed transistor
optocouplers but with shorter
propagation delays and higher
CTR. The HCPL-4504/0454 and
HCNW4504 also have a guaran-
teed propagation delay difference
(t
PLH
- t
PHL
). These features make
these optocouplers an excellent
solution to IPM inverter dead time
and other switching problems.
