Overview

Datasheet ISL3232E, ISL4221E, ISL4223E QFN Packaged, ±15kV ESD Protected, +2.7V to +5.5V, 150nA, 250kbps, RS-232 Transmitters/Receivers The ISL3232E, ISL4221E, and ISL4223E devices are 2.7V to 5.5V powered RS-232 transmitters/receivers that meet ElA/TIA-232 and V.28/V.24 specifications, even at VCC = 3.0V.

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 power consumption and even lower standby power consumption are critical.

Key Features

  • of the IC’s and AN9863 summarizes the features of each device comprising the 3V RS-232 family. Features.
  • Available in near chip scale QFN (5mmx5mm) package, which is 40% smaller than a 20 Ld TSSOP.
  • ESD protection for RS-232 I/O pins to ±15kV (IEC61000).
  • Meets EIA/TIA-232 and V.28/V.24 specifications at 3V.
  • RS-232 compatible with VCC = 2.7V.
  • On-chip voltage converters require only four external 0.1µF capacitors.
  • Manual and automatic powerdown.
