Description

The ICL3222CBZ is a powered RS-232 Transmitter/Receiver with part marking. It meets ElA/TIA-232 and V.28/V.24 specifications, even at VCC = 3V. Efficient on-chip charge pumps, coupled with manual and automatic power-down functions, reduce the A trickle. Data rates greater than 250kbps 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 automatic power-down function which powers down the on-chip power-supply and driver circuits. This occurs when an attached peripheral device is shut off or the RS-232 cable is removed, conserving system power automatically without changes to the hardware or operating system. This device power up again when a valid RS-232 voltage is applied to any receiver input.
15kV ESD protected (human body model)
Low power, Pin-compatible upgrade for 5V MAX221
Latch-up free
On-chip voltage converters require only four external 0.1µF capacitors
Receiver hysteresis for improved noise immunity
250kbps Guaranteed minimum data rate
6V/ms Guaranteed minimum slew rate
1mA Low supply current in power-down state
