1 / 17 page March 2006 Rev 6 1/17 17 ST3237E ± 15KV ESD-protected, 1 µA, 3 to 5.5V, 250Kbps RS-232 Transceiver with stand-by Feature summary s ESD protection for RS-232 I/O pins – ±15KV human body model – ±8KV IEC 1000-4-2 contacts discharge s 1 µA low power shutdown with receivers active s Guaranteed data rate – 250Kbps (normal operation) – 1Mbps (very high speed operation) s Guaranteed slew rate range –6V/ µs (normal operation) –24V/ µs (very high speed operation) s 0.1 µF external capacitors s Flow-through pinout s Low supply current 300 µA s Available in SSOP-28 and SO-28 Description The ST3237E is a 3V to 5.5V powered EIA/TIA- 232 and V.28/V.24 communication interfaces high data-rate capability and enhanced electrostatic discharge (ESD) protection at ±8KV using IEC1000-4-2 contact discharge and ±15kV using Human Body Model (HBM). The other pins are protected with standard ESD protection at ±2kV 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 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 maintaining RS-232 output levels..
