Übersicht
Equivalent
- MAX3232CDBR (higher ESD protection, similar specs)
- SP3232EBCY (Sipex/Exar, pin-compatible)
- ADM3222ARWZ (Analog Devices alternative)
- ST3232CDR (STMicroelectronics equivalent)
- TRS3232EIDBR (Texas Instruments alternative).
These offer similar 3.3V operation, RS-232 compatibility, and small footprint (SOIC package). Check datasheets for minor variations in ESD ratings or power consumption.
Features
- Single-Channel RS-232 Transceiver: Supports full-duplex communication.
- Wide Voltage Range: Operates from 3.0V to 5.5V, compatible with 3.3V and 5V systems.
- Low Power Consumption: Auto-shutdown mode reduces power when inactive.
- High Data Rate: Up to 250kbps transmission speed.
- Enhanced ESD Protection: ±15kV (Human Body Model) on I/O lines.
- Small Package: SSOP-16 (DBR) for space-constrained designs.
- On-Chip Charge Pump: Eliminates need for external ±12V supply.
Ideal for battery-powered, portable, and industrial applications requiring robust RS-232 communication.
Pinout
### Key Functions:
- Dual RS-232 drivers/receivers (2 TX, 2 RX).
