DESCRIPTION
The 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
SSOP
TSSO P
operation mode and 1Mbps in the very high speed
operation mode while maintaning RS-232 output
levels.
