- Meets or exceeds the requirements of TIA/EIA-232-F and ITU V.28 standards
- Three drivers and five receivers
- Operates up to 250 kbps
- Low active current: 300-µA typical
- Low standby current: 1-µA typical
- External capacitors: 4 × 0.1 µF
- Accepts 5-V logic input with 3.3-V supply
- Always-active noninverting receiver output (ROUT2B)
- Operating temperature
- TRS3243C: 0°C to 70°C
- TRS3243I: –40°C to 85°C

- Automatic power-down feature to disable driver outputs when no valid RS-232 signal is sensed
The TRS3243 device consists of three line drivers, and five line receivers, which is ideal for DE-9 DTE interface. A ±15-kV ESD (HBM) protection pin-to-pin (serial-port connection pins, including GND). Flexible power features save power automatically. Special outputs ROUT2B and INVALID are always enabled to allow checking for ring indicator and valid RS232 input.
