Transceivers with Enhanced Automatic

Powerdown

Features

• ±15kV ESD Protected (Human Body Model)

• Manual and Enhanced Automatic Powerdown Features

The Intersil ICL32XX devices are 3.0V to 5.5V powered

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

• Meets EIA/TIA-232 and V.28/V.24 Specifications at 3V

• Latch-Up Free

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 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 as well. Data rates greater than 1Mbps 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.

• On-Chip Voltage Converters Require Only Four External

0.1µF Capacitors

• Guaranteed Mouse Driveability (ICL3245)

• “Ready to Transmit” Indicator Output (ICL3225, ICL3227)

• Receiver Hysteresis For Improved Noise Immunity

• Guaranteed Minimum Data Rate . . . . . . . . . . . . . . 1Mbps

• Low Skew at Transmitter/Receiver Input Trip Points. . . 10ns

• Guaranteed Minimum Slew Rate . . . . . . . . . . . . . . 24V/µs

• Wide Power Supply Range . . . . . . . Single +3V to +5.5V

• Low Supply Current in Powerdown State. . . . . . . . . . .1µA

The ICL3245 is a 3 driver, 5 receiver device that provides a

complete serial port suitable for laptop or notebook

computers. It also includes a noninverting always-active

receiver for “wake-up” capability.

These devices, feature an enhanced automatic

powerdown 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. These devices power back up, automatically, whenever

they sense a transition on any transmitter or receiver input.

• Any System Requiring RS-232 Communication Ports

- Battery Powered, Hand-Held, and Portable Equipment

- Laptop Computers, Notebooks, Palmtops

- Modems, Printers and other Peripherals

- Digital Cameras
