intersil ISL4244E Manual
Update: 01 October, 2023
The ISL4238E/44E/45E are 2.7V to 5.5V powered RS-232 transmitters/receivers which meet ElA/TIA-232 and V.28/V.24 specifications, even at VCC = 3.0V. Additionally, they provide ±15kV ESD protection (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. 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. The ISL4238E is a 5 driver, 3 receiver device optimized for DCE applications.
