The Intersil ISL4238E, ISL4244E and ISL4245E devices are
2.7V to 5.5V powered RS-232 transmitters/receivers which
meet ElA/TIA-232 and V.28/V.24 specifications, even at
VCC = 3.0V. Additionally, they provide ±15kV ESD protection
(IEC6100-4-2 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 enhanced
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 (ISL4238E/ISL4244E)/1Mbps (ISL4245E) are
guaranteed at worst case load conditions.
