One Microamp Supply-Current, +3V to +5.5V,

250kbps, RS-232 Transmitters/Receivers

The Intersil ICL32XX devices are 3.0V to 5.5V powered

RS-232 transmitters/receivers which meet ElA/TIA-232 and

V.28/V.24 specifications, even at V

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 manual and automatic

powerdown functions (except for the ICL3232), reduce 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

family is fully compatible with 3.3V only systems, mixed 3.3V

and 5.0V systems, and 5.0V only systems.

The ICL324X are 3-driver, 5-receiver devices that provide a

complete serial port suitable for laptop or notebook

computers. Both devices also include noninverting always-

active receivers for “wake-up” capability.

The ICL3221, ICL3223 and ICL3243, feature an

automatic powerdown 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.

These devices power up again when a valid RS-232

voltage is applied to any receiver input.

by this data sheet, while Application Note AN9863

summarizes the features of each device comprising the

ICL32XX 3V family.
