DESCRIPTION
The MAX3237E consists of five line drivers, three line receivers, and a dual charge-pump circuit with
±
15-kV
ESD protection pin to pin (serial-port connection pins, including GND). The device meets the requirements of
TIA/EIA-232-F and provides the electrical interface between an asynchronous communication controller and the
serial-port connector. The charge pump and four small external capacitors allow operation from a single 3-V to
5.5-V supply. This device operates at data signaling rates of 250 kbit/s in normal operating mode
(MBAUD = GND) and 1Mbit/s when MBAUD = V
CC
. The driver output slew rate is a maximum of 30 V/
μ
s.
DESCRIPTION (CONTINUED)
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
μ
A. 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.
