The MAX1480A/MAX1480B/MAX1490A/MAX1490B typi-
cally withstand 1600V
RMS
(1 minute) or 2000V
RMS
(1 second). The logic inputs can be driven from
TTL/CMOS-logic with a series resistor, and the received
data output can directly drive TTL or CMOS-logic families
with only resistive pull-up.
Low-Power S hutdown Mode
The SD pin shuts down the oscillator on the internal power
driver. With the primary side in shutdown, no power is
transferred across the isolation barrier. The DI and DE
optocouplers, however, still consume current if the drive
signals on the non-isolated side are low. Therefore, leave
DI
′
and DE
′
high or floating when in shutdown mode.
