munication software (such as LapLink鈩?. Transmitters
can be paralleled to drive multiple receivers. Figure 1
shows a complete system connection.
When
FORCEOFF
is driven to ground or when the Auto-
Shutdown Plus circuitry senses that all receiver and
transmitter inputs are inactive for more than 30sec, the
transmitters are disabled and the outputs go into a high-
impedance state. When powered off or shut down, the
outputs can be driven to 鹵12V. The transmitter inputs
do not have pull-up resistors. Connect unused inputs to

RS-232 Receivers
The receivers convert RS-232 signals to CMOS-logic
output levels. The MAX3224E鈥揗AX3227E feature
inverting outputs that always remain active (Table 1).
The MAX3244E/MAX3245E have inverting three-state

NEW MAX3244E/MAX3245E: IN SHUTDOWN, R2OUTB IS USED TO MONITOR
EXTERNAL DEVICES AND R2OUT IS THREE STATED, ELIMINATING A CURRENT
PATH THROUGH THE UART'S PROTECTION DIODE.

when the UART and interface are shut down.
