DATASHEET
ISL4238E, ISL4244E, ISL4245E
QFN Packaged, В±15kV ESD Protected, +2.7V to +5.5V, 10Nanoamp, 250kbps/
1Mbps, RS-232 Transceivers with Enhanced Automatic Power-down
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 В±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 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.
The ISL424xE are 3 driver, 5 receiver (DTE) devices that,
coupled with the QFN package, provide the industry’s
smallest, lowest power complete serial port suitable for …
