+3V to +5.5V, 1 Microamp, 250kbps ,
RS-232 Trans mitter/Receiver
Features
• ±15kV ESD Protected (Human Body Model)
The Intersil ICL3310 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,
SP310A, and LT1X80/A
V.28/V.24 specifications, even at V
= 3.0V. Targeted
CC
• Single SHDN Pin Disables Transmitters and Receivers
• Meets EIA/TIA-232 and V.28/V.24 Specifications at 3V
• Latch-Up Free
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.
• 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
The single pin powerdown function (SHDN = 0) disables all
the transmitters and receivers, while shutting down the
charge pump to minimize supply current drain.
Table 1 summarizes the features of the ICL3310, while
Application Note AN9863 summarizes the features of each
device comprising the ICL32XX 3V family.
