ST3237EB 15 kV ESD protected, 1 A, 3 to 5.5 V, 250 kbps RS-232 transceiver with stand-by Features ESD protection for RS-232 I/O pins 15 kV human body model 8 kV IEC 1000-4-2 contacts discharge 1 A low power shutdown with receivers active Guaranteed data rate 250 kbps (normal operation) 1 Mbps (very high speed operation) Guaranteed slew rate range SSOP SOP 6 V/s (normal operation) 24 V/s (very high speed operation) 0.1 F external capacitors Flow-through pinout Low supply current 300 A Available in SSOP28 and SO-28 operation mode and 1 Mbps in the very high speed operation mode while maintaining RS-232 Description output levels. The ST3237E is a 3 V to 5.5 V powered EIA/TIA- 232 and V.28/V.24 communication interfaces high data-rate capability and enhanced electrostatic discharge (ESD) protection at 8 kV using IEC1000-4-2 contact discharge and 15 kV using Human Body Model (HBM). The other pins are protected with standard ESD protection at 2 kV using HBM method. The ST3237C 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 3 V to 5.5 V supply using a dual charge pump. The device is guaranteed to run at data rates of 250 kbps in the normal Table 1.
