The IH5043 analog switch uses an improved, high voltage
CMOS monolithic technology. These devices provide ease
of use and performance advantages not previously
available from solid state switches.
Key performance advantage is TTL compatibility and ultra
low power operation. The quiescent current requirement is
less than 1mA. Also, the IH5043 guarantees Break-Before-
Make switching, accomplished by extending the tON time
(300ns Typ), so that it exceeds tOFF time (200ns Typ). This
insures that an ON channel will be turned OFF before an
OFF channel can turn ON. The need for external logic
required to avoid channel to channel shorting during
switching is eliminated.
