Renesas Electronics Corporation QFN Packaged, ±15kV ESD Protected, +2.7V to +5.5V, 10nA, 250kbps, RS-232 Transmitters/Receivers ISL4243EIRZ

Description
Intersil's ISL4241E, ISL4243E 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 VCC = 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 notebook and laptop computers 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 10nA trickle. Tiny 5mmx5mm Quad Flat No-Lead (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 ISL4241E, ISL4243E's are 3 driver, 5 receiver devices that, coupled with the 5x5 QFN package, provide the industry's smallest, lowest power complete serial port suitable for PDAs, and laptop or notebook computers. The 32 Ld 5X5 QFN requires 60% less board area than a 28 Ld TSSOP, and is nearly 20% thinner. The devices also include a noninvertingbralways -active receiver for "wake-up" capability.brbr The ISL4243E features an automatic power-down 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 both the ISL4241E and ISL4243E, while Application Note AN9863 summarizes the features of each device comprising the 3V RS-232 family.
