DESCRIPTIONThe ST3237 is a 3V to 5.5V powered EIA/TIA-232
and V.28/V.24 communication interfaces high
data-rate capabilities. ST3237 is a transceiver (5
drivers, 3 receivers) for fast modem applications.
The device has a proprietary low-dropout
transmitter output stage providing true RS-232
performance from a 3V to 5.5V supply using a
dual charge pump. The device is guaranteed to
run at data rates of 250Kbps in the normal
operation mode and 1Mbps in the very high speed
operation mode while maintaning RS-232 output
levels.

PIN CONFIGURATION
ABSOLUTE MAXIMUM RATINGS Absolute Maximum Ratings are those values beyond which damage to the device may occur. Functional operation under these condition is
not implied. V+ and V- can have a maximum magnitude of +7V, but their absolute addition can not exceed 13 V.
