Data Sheet  
April 2004  
FN8038.3  
QFN Packaged, ±15kV ESD Protected,  
+2.7V to +5.5V, 10Nanoamp, 250kbps/  
1Mbps, RS-232 Transceivers with  
Enhanced Automatic Powerdown  
Features  
• Parameters Fully Specified for 10% Tolerance Supplies  
and Full Industrial Temp Range  
• Available in Small QFN (5mm x 5mm) Package which is  
60% Smaller than a 28 Lead TSSOP  
The Intersil ISL4238E/44E/45E devices are 2.7V to 5.5V  
powered RS-232 transmitters/receivers which meet  
ElA/TIA-232 and V.28/V.24 specifications, even at  
• ESD Protection for RS-232 I/O Pins to ±15kV (IEC6100)  
• DTE (ISL4244E/45E) and DCE (ISL4238E) Versions  
• Lowest Supply Current in Powerdown . . . . . . . . . . . .10nA  
V
= 3.0V. Additionally, they provide ±15kV ESD protection  
CC  
(IEC6100-4-2 Air Gap and Human Body Model) on  
transmitter outputs and receiver inputs (RS-232 pins).  
Targeted 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 10nA trickle. Tiny 5mm x 5mm Quad Flat No-  
Lead (QFN) packaging and the use of small, low value  
capacitors ensure board space savings as well. Data rates  
greater than 250kbps (ISL4238E/44E)/1Mbps (ISL4245E)  
are guaranteed at worst case load conditions.  
• Active Feedback Resistors on T and Logic Inputs  
X
(ISL4238E)  
• Flow Through Pinouts  
• Manual and Enhanced Automatic Powerdown Features  
• Guaranteed Minimum Data Rate  
250kbps (ISL4238E/44E) / 1Mbps (ISL4245E)  
• Latch-Up Free  
• On-Chip Charge Pumps Require Only Four External  
0.1µF Capacitors  
The ISL424XE are 3 driver, 5 receiver (DTE) devices that,  
coupled with the QFN package, provide the industry’s  
smallest, lowest power complete serial port suitable for  
PDAs, and laptop or notebook computers. The 5x5 QFN  
requires 60% less board area than a 28 lead TSSOP, and is  
nearly 20% thinner. The devices also include a noninverting  
always-active receiver for “wake-up” capability.  
• Wide Power Supply Range. . . . . . . Single +2.7V to +5.5V  
• Meets EIA/TIA-232 and V.28/V.24 Specifications at 3V  
• RS-232 Compatible with V  
= 2.7V  
CC  
• Pb-free Available as an Option  
Applications  
The ISL4238E is a 5 driver, 3 receiver device optimized for  
DCE applications with full hardware handshaking. It also  
includes a noninverting always-active receiver for RING  
INDICATOR monitoring. Transmitter and logic inputs include  
active feedback resistors that retain the input state once  
driven to a valid logic level.  
• Any Space Constrained System Requiring RS-232 Ports  
- Battery Powered, Hand-Held, and Portable Equipment  
- Laptop Computers, Notebooks  
- PDAs and Palmtops, Data Cables  
- Cellular/Mobile Phones, Digital Cameras, GPS  
Receivers  
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  
30sec. These devices power back up, automatically,  
whenever they sense a transition on any transmitter or  
receiver input.
