Wake-Up Feature
The
SP235B
,
SP236B
,
SP240B
and
SP241B
have a wake-up feature that keeps all receivers
in an enabled state when the device is in the
shutdown mode.
Table 2
defines the truth table
for the wake-up function. Timing for the wake-up
function is shown in
Figure 6
.
If the
SP235B
,
SP236B
,
SP240B
and
SP241B
are powered up in the shutdown state (SD driven
high during V
power up), the part must remain
in a powered on state for a minimum of 3ms
before the wake-up function can be used. After
the 3ms wait time, there is a 2ms delay time
before data is valid for both enable and disable
