FN6017.3
±15kV ESD Protected, +3V to +5.5V,
1 Microamp, 250Kbps, RS-232
Transmitter/Receiver
Features
• ESD Protection for RS-232 I/O Pins to ±15kV (IEC61000)
• Drop In Replacement for MAX3384E, SP385E
The Intersil ISL83384E contains 3.0V to 5.5V powered
RS-232 transmitters/receivers which meet ElA/TIA-232 and
• Low Power, Pin Compatible Upgrade for 5V MAX222,
SP310E, ADM222, and LT1780
V.28/V.24 specifications, even at V
= 3.0V. Targeted
CC
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 a manual powerdown function
reduces the standby supply current to a 1µA trickle. Small
footprint 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. This device is fully compatible with 3.3V only
systems, mixed 3.3V and 5.0V systems, and 5.0V only
systems.
• Single SHDN Pin Disables Transmitters and Receivers
• Meets EIA/TIA-232 and V.28/V.24 Specifications at 3V
• RS-232 Compatible with V
• Latch-Up Free
= 2.7V
CC
• On-Chip Voltage Converters Require Only Four External
0.1µF Capacitors
• Receiver Hysteresis For Improved Noise Immunity
• Very Low Supply Current . . . . . . . . . . . . . . . . . . . . 0.3mA
• Guaranteed Minimum Data Rate . . . . . . . . . . . . 250Kbps
• Guaranteed Minimum Slew Rate . . . . . . . . . . . . . . . 6V/µs
• Wide Power Supply Range. . . . . . . . Single +3V to +5.5V
• Low Supply Current in Powerdown State. . . . . . . . . .<1µA
• Pb-Free Available (RoHS Compliant)
The single pin powerdown function (SHDN = 0) disables all
the transmitters and receivers, while shutting down the
charge pump to minimize supply current drain.

NOTE: Intersil Pb-free products employ special Pb-free material sets;
molding compounds/die attach materials and 100% matte tin plate
termination finish, which are RoHS compliant and compatible with
both SnPb and Pb-free soldering operations. Intersil Pb-free products
are MSL classified at Pb-free peak reflow temperatures that meet or
exceed the Pb-free requirements of IPC/JEDEC J STD-020.
