Renesas Electronics Corporation QFN Packaged, ±15kV ESD Protected, +2.7V to +5.5V, 150nA, 250kbps, RS-232 Transmitters/Receivers ISL4221EIRZ-T

Description
The Intersil ISL3232E and ISL4221E, ISL4223E devices are 2.7V to 5.5V powered RS-232 transmitters/receive rs which meet ElA/TIA-232 and V.28/V.24 specifications, even atbr VsubCC/sub = 3.0V. Additionally, they provide ±15kV ESD protection (IEC61000-4-2 Air Gap and Human Body Model) on transmitter outputs and receiver inputs (RS-232 pins). Targeted applications are PDAs, Palmtops, and hand-held products where the low operational, and even lower standby, power consumption is critical. Efficient on-chip charge pumps, coupled with manual and automatic power-down functions, reduce the standby supply current to a 150nA trickle. Tiny 5mmx5mm bQuad Flat No-Lead/b (QFN) packaging and the use of small, low value capacitors ensure board space savings as well. Data rates greater than 250kbps are guaranteed at worst case load conditions.brbr The ISL4221E is a 1 driver, 1 receiver device and the ISL3232E and ISL4223E are 2 driver,br2 receiver devices that, coupled with the 5mmx5mm QFN package, provide the industry's smallest, lowest power serial port suitable for PDAs, and hand-held applications. The 5mmx5mm QFN requires 40% less board area than a 20 Ld TSSOP, and is nearly 20% thinner.brbr The bISL4221E, ISL4223E/b versions feature an bautomatic power-down/b function that powers down the on-chip power supply and driver circuits. This occurs when an attached peripheral device is shut off or the RS-232 cable is removed, conserving system power automatically without changes to the hardware or operating system. It powers up again when a valid RS-232 voltage is applied to any receiver input.brbr Table 1 summarizes the features of the IC's, while Application Note AN9863 summarizes the features of each device comprising the 3V RS-232 family.
