ST232CTR STMicroelectronics

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 DIP SOP 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 SOP Large TSSOP 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 F). Typical applications are in: portable computers, low power modems, interfaces translation, battery powered RS-232 system, multi-drop RS-232 networks. Table 1.
