By connecting FORCEON to
INVALID
, the device shuts
down when no valid receiver level and no receiver or
transmitter edge is detected for 30sec. It wakes up
when a valid receiver level or receiver or transmitter
edge is detected.
By connecting FORCEON and
FORCEOFF
to
INVALID
,
the device shuts down when no valid receiver level is
detected and wakes up when a valid receiver level is
detected.
A system with AutoShutdown Plus may need time to
wake up. Figure 4 shows a circuit that forces the
transmitters on for 100ms, allowing enough time
for another system to realize that the MAX3233E/
MAX3235E is awake. If another system outputs valid
RS-232 signal transitions within that time, the RS-232
ports on both systems remain enabled.
S oftware-Controlled S hutdown
If direct software control is desired, use
INVALID
to
indicate DTR or Ring Indicator signal. Tie
FORCEOFF
and FORCEON together to bypass the AutoShutdown
Plus so the line acts like a
SHDN
input.
±15kV ES D Protec tion
As with all Maxim devices, ESD-protection structures are
incorporated on all pins to protect against electrostatic
discharges encountered during handling and assembly.
The driver outputs and receiver inputs have extra pro-
tection against static electricity. Maxim’s engineers have
developed state-of-the-art structures to protect these
pins against ESD of ±15kV without damage. The ESD
structures withstand high ESD in all states: normal
operation, shutdown, and powered down. After an ESD
