ST232AB ST232AC Very high speed, ultra low power consumption 5 V powered RS-232 drivers and receivers Features Supply voltage range: 4.5 to 5.5 V Supply current no load (typ): 1.5 mA Transmitter output voltage swing (typ): 9 V Transition slew rate (typ.): 12 V/s Receiver propagation delay (typ.): 0.1 s Receiver input voltage range: 30 V Data rate (typ.): 400 kbps/s TSSOP16 SO-16 Operating temperature range: -40 to 85 C 0 to 70 C Description The ST232AB/AC 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 ST232AB/AC 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 networks. Table 1.
