ST3237 General 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 operation mode and 1Mbps in the very high speed operation mode while maintaning RS-232 output levels

ST3237 Maximum Ratings

Symbol	Parameter	Value	Unit
V_CC	Supply Voltage	-0.3 to 6	V
V+	Doubled Voltage Terminal	-0.3 to 7	V
V-	Inverted Voltage Terminal	0.3 to -7	V
V+ +\|V-\|		13	V
T_IN	Transmitter Input Voltage Range	-0.3 to 6	V
SHDN,EN		-0.3 to 6	V
V_HSCI	Very High Speed Control Input	-0.3 to (VCC +0.3)	V
R_IN	Receiver Input Voltage Range	± 25	V
T_OUT	Transmitter Output Voltage Range	± 13.2	V
R_OUT R_OUTB	Receiver Output Voltage Range	-0.3 to (V_CC + 0.3)	V
t_SHORT	Short Circuit Durtion on T_OUT (one at a time)	Continuous
T_stg	Storage Temperature Range	-65 to 150

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.
