ISL4241E, ISL4243E QFN package, ± 15kv ESD protection, +2.7 volts to +5.5 volts, 10 mAh, 250 kbps, RS-232 transmitter/receiver/receiver
ISL4241E and ISL4243E devices of INTERSIL are 2.7V to 5.5V to meet the following RS-232 transmitter/receiver ELA/TIA-232 and V.28/V.24 specifications, even in VCC 3.0V. In addition, they also provide ± 15kV ESD protection (IEC61000-4-2 air gap and human model) developer output and receiver input (RS-232 pin). The target application is PDA, palm computer, laptop and laptop, and laptops, and even lower standby power consumption is important. Effective charging pump, equipped with manual and automatic power -off function, reduce the current of the backup power supply to 10 mAh. The packaging and use of miniature 5mm x 5 mm four -flat lead (QFN) small capacitors ensure the board space of the board of directors. The data rate is greater than 250kbps under the worst load conditions. ISL4241E and ISL4243E are 3 drivers, 5 receiver devices plus 5x5 QFN package, which can provide the industry's smallest and lowest complete serial port for PDA, laptop or laptop. This 32 LD 5X5 QFN requires 60%less than 28 LD
Tssop, and it is almost 20%thinner. These devices also include non -rotation for awakening " that are always in a state of activity. ISL4243E has the automatic power off -chip power supply and driver circuit. When the connected peripheral device is closed or the RS-232 cable is removed
