TRSF3232E
- Operates with 3V to 5.5V VCC supply
- Operates up to 1Mbit/s
- Low supply current: 300µA typical
- External capacitors: 4 × 0.1µF
- Accept 5V logic input with 3.3V supply
- Latch-up performance exceeds 100mA Per JESD 78, class II
- ESD protection for RS-232 pins
- ±15kV Human-Body Model (HBM)
- ±15kV IEC 61000-4-2 air-gap discharge

The TRSF3232E consists of two line drivers, two line receivers, and a dual charge-pump circuit with ±15kV ESD protection pin to pin (serial-port connection pins, including GND). This device provides the electrical interface between an asynchronous communication controller and the serial-port connector. The charge pump and four small external capacitors allow operation from a single 3V to 5.5V supply. The TRSF3232E operates at data signaling rates up to 1Mbit/s and a driver output slew rate of 14V/µs to 150V/µs.
