ISL83384ECA-T

NOT RECOMMENDED FOR NEW DESIGNS RECOMMENDED REPLACEMENT PART ICL3222E ISL83384E DATASHEET FN6017 Rev 3.00 March 15, 2005 ±15kV ESD Protected, +3V to +5.5V, 1 Microamp, 250Kbps, RS-232 Transmitter/Receiver The Intersil ISL83384E contains 3.0V to 5.5V powered RS-232 transmitters/receivers which meet ElA/TIA-232 and V.28/V.24 specifications, even at VCC = 3.0V. 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 a manual powerdown function reduces the standby supply current to a 1A 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. Features • ESD Protection for RS-232 I/O Pins to 15kV (IEC61000) • Drop In Replacement for MAX3384E, SP385E • Low Power, Pin Compatible Upgrade for 5V MAX222, SP310E, ADM222, and LT1780 • Single SHDN Pin Disables Transmitters and Receivers • Meets EIA/TIA-232 and V.28/V.24 Specifications at 3V • RS-232 Compatible with VCC = 2.7V • Latch-Up Free • On-Chip Voltage Converters Require Only Four External 0.1F Capacitors The single pin powerdown function (SHDN = 0) disables all the transmitters and receivers, while shutting down the charge pump to minimize supply current drain. • Receiver Hysteresis For Improved Noise Immunity Table 1 summarizes the features of the ISL83384E, while Application Note AN9863 summarizes the features of each device comprising the ICL32XX 3V family. • Guaranteed Minimum Data Rate . . . . . . . . . . . . 250Kbps • Very Low Supply Current . . . . . . . . . . . . . . . . . . . . 0.3mA • Guaranteed Minimum Slew Rate . . . . . . . . . . . . . . . 6V/s • Wide Power Supply Range . . . . . . .
