The transceivers incorporate three transmitters and five receivers in a tiny 5 x 5mm MFLP package specifically designed to provide compact low-power high-speed RS232 serial data ports for the next wave of PDAs, handheld appliances, notebook PCs and other battery-powered devices where space and power consumption are major issues.
The transceivers provide a complete RS232 serial port interface solution to TTL logic levels at datarates of 250Kbit/s and 1Mbit/s.
A feature of these new transceivers is their miniscule packaging in a tiny 32-pad 5 x 5mm micro lead frame plastic (MLFP) package.
The new MLFP package provides many benefits where space and power dissipation are important.

At a mere 5 x 5 x 0.9mm, the MLFP package is some 60% smaller than the SSOP packages it replaces.
Small pads on the underside perimeter provide circuit contact so there are no leads to become bent during handling or assembly.
Special manufacturing equipment is not needed.
The new ISL4241EIR, ISL4243EIR, ISL4244EIR and ISL4245EIR ICs join Intersil's Linearlink family of serial transceivers The transceivers also feature highly efficient on-chip charge pumps which coupled with manual and automatic power-down functions reduce standby supply current in power down mode to a tiny 10nA trickle - 100 times lower than alternative devices.
The devices operate from a 2.7 to 5.5V supply and meet all EIA/TIA232 and V.28/V.24 specifications, even at 3V while providing full ESD protection for all RS232 I/O pins to 15kV (IEC1000).
"Our new MLFP transceivers are the world's smallest complete RS232 serial ports and offer up to 1Mbit/s datarates and full 15kV ESD protection per IEC1000-4-2.
They are ideal for newer portable devices requiring smaller packaging, lower power usage and high electrostatic discharge (ESD) protection while offering reliable high-speed data transfer in the 3-5V supply range", said Davin Yuknis, marketing manager for Intersil's Analogue Solutions Products.
The ISL424X family offers a choice of manual or automatic power down with the option of enhanced power-down if required.
All the new transceivers are available now.
Intersil also offers a wide variety of ESD-protected and non-ESD-protected serial data transceivers to accommodate a large spectrum of applications in both commercial and industrial temperature environments.
