TRS3232
- RS-232 Bus-terminal ESD protection exceeds ±15 kV using human-body model (HBM)
- Meets or exceeds the requirements of TIA/EIA-232-F and ITU V.28 standards
- Operates with 3-V to 5.5-V VCC supply
- Operates up to 250 kbps
- Two drivers and two receivers
- Low supply current: 300-µA typical
- External capacitors: 4 × 0.1 µF
- Accepts 5-V logic input with 3.3-V supply
- Alternative high-speed terminal-compatible devices s (1 Mbps)
- SN65C3232 (–40°C to 85°C)
- SN75C3232 (0°C to 70°C)
The TRS3232 consists of two line drivers, two line receivers, and a dual charge-pump circuit with ±15-kV ESD protection terminal-to-terminal (serial-port connection terminals, including GND). The device meets the requirements of TIA/EIA-232-F and 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 one 3-V to 5.5-V supply. The devices operate at data-signaling rates up to 250 kbps and a maximum of 30-V/µs driver-output slew rate.
