The Intersil ICL3310E 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 1µA trickle. Small footprint packaging of the ICL3310E, 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.
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 ICL3310E, while Application Note AN9863 summarizes the features of each device comprising the ICL32XX 3V family.
