Overview
® SP3223B/3243B Intelligent +3.
0V to +5.
5V RS-232 Transceivers ■ Meets true EIA/TIA-232-F Standards from a +3.
0V to +5.
5V power supply ■ Interoperable with EIA/TIA-232 and adheres to EIA/TIA-562 down to a +2.
7V power source ■ AUTO ON-LINE® circuitry automatically wakes up from a 1µA shutdown ■ Minimum 250kbps data rate under load ■ Regulated Charge Pump Yields Stable RS-232 Outputs Regardless of VCC Variations ■ ESD Specifications: +2kV Human Body Model DESCRIPTION The SP3223B and SP3243B products are RS-232 transceiver solutions intended for portable or hand-held applications such as notebook and palmtop computers.
The SP3223B and SP3243B use an internal high-efficiency, charge-pump power supply that requires only 0.
1µF capacitors in 3.
3V operation.
This charge pump and Sipex's driver architecture allow the SP3223B/3243B series to deliver compliant RS-232 performance from a single power supply ranging from +3.
0V to +5.
5V.
The SP3223B is a 2-driver/2-receiver device, and the SP3243B ...
