ST232C

ST232B ST232C 5 V powered multi-channel RS-232 drivers and receivers Features ■ Supply voltage range: 4.5 to 5.5 V ■ Supply current no load (typ.): 5 mA ■ Transmitter output voltage swing (typ): ±7.8 V ■ Controlled output slew rate ■ Receiver input voltage range: ± 30 V ■ Data rate (typ.): 220 kbps ■ Operating temperature range: – -40 ° to 85 °C – 0 ° to 70 °C ■ Compatible with MAX232 and MAX202 Description The ST232 is a 2 driver, 2 receiver device following EIA/TIA-232 and V.28 communication standard. It is particularly suitable for applications where ±12 V is not available. The ST232 uses a single 5 V power supply and only four external capacitors (0.1 µF). Typical applications are in: portable computers, low power modems, interfaces translation, battery powered RS-232 system, multi-drop RS-232 networks. DIP SOP Large SOP TSSOP Table 1.
