ICL3225ECAZ

The ICL3225ECAZ is a RS-232 Transmitter/Receiver with marking. It meets ElA/TIA-232 and V.28/V.24 specifications, even at VCC = 3V. Additionally, it provides ±15kV ESD protection on transmitter outputs and receiver inputs. Efficient on-chip charge pumps, coupled with manual and enhanced automatic power-down functions, reduce the standby supply current to 1mA trickle. Data rates greater than 1Mbps are guaranteed at worst case load conditions. This family is fully compatible with 3.3V only systems, mixed 3.3 and 5V systems and 5V only systems. It features an enhanced automatic power-down function which powers down the on-chip power supply and driver circuits. This occurs when all receiver and transmitter inputs detect no signal transitions for a period of 30s. This device power back up, automatically, whenever they sense a transition on any transmitter or receiver input.
