ICL3224, ICL3226, ICL3238

1µA, +3V to +5.5V, 250kbps, RS-232 Transceivers with Enhanced Automatic

Powerdown

The ICL3224, ICL3226, and ICL3238 (ICL32xx)

devices are 3.0V to 5.5V powered RS-232

transmitters/receivers that meet ElA/TIA-232 and

Features

• Pb-free (RoHS compliant)

• ±15kV ESD protected (human body model)

• Manual and enhanced automatic powerdown

V.28/V.24 specifications, even at V = 3.0V.

Targeted applications are PDAs, Palmtops, and

notebook and laptop computers where low

operational power consumption and even lower

standby power consumption are critical. Efficient

on-chip charge pumps, coupled with manual and

enhanced automatic powerdown functions, reduce

the standby supply current to a 1µA trickle. Small

footprint packaging, and the use of small, low value

capacitors ensure board space savings. Data rates

greater than 250kbps are ensured 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.

features

• Drop in replacements for MAX3224, MAX3226,

MAX3238

• Meets EIA/TIA-232 and V.28/V.24 specifications

at 3V

• Latch-up free

• RS-232 compatible with V = 2.7V

• On-chip voltage converters require only four

external 0.1µF capacitors

• Flow-through pinout (ICL3238)

The ICL3238 is a 5 driver, 3 receiver device that

includes a noninverting always-active receiver for

Ring Indicator monitoring.

• “Ready to transmit” indicator output (ICL3224/26)

• Receiver hysteresis for improved noise immunity

• Ensured minimum data rate: 250kbps

• Ensured minimum slew rate: 6V/µs

The ICL32xx devices feature an enhanced automatic

powerdown function that powers down the on-chip

power supply and driver circuits. Powerdown occurs

when all receiver and transmitter inputs detect no

signal transitions for a period of 30s. These devices

power back up automatically whenever they sense a

transition on any transmitter or receiver input.

• Wide power supply range: Single +3V to +5.5V

• Low supply current in powerdown state: 1µA

Applications

• Any system requiring RS-232 communication ports

Table 1 summarizes the features of the devices

represented by this datasheet, and AN9863

summarizes the features of each device in the

ICL32xx 3V family.
