MAX3237E
SLLS709B –MAY 2006–REVISED JANUARY 2010 www.ti.com
The MAX3237E transmitters are disabled and the outputs are forced into high-impedance state when the device
is in shutdown mode (SHDN = GND) and the supply current falls to less than 1 mA. Also, during shutdown, the
onboard charge pump is disabled; V+ is lowered to V
CC
, and V– is raised toward GND. Receiver outputs also
can be placed in the high-impedance state by setting enable (EN) high. ROUT1B remains active all the time,
regardless of the EN and SHDN condition.
The MAX3237EC is characterized for operation from 0°C to 70°C. The MAX3237EI is characterized for operation
from –40°C to 85°C.
