Data Sheet June 2004

+/- 15kV ESD Protected, +3V to +5.5V, Low Power, 250kbps, RS-232 Transmitters/Receivers

The Intersil ICL32X7E devices are 3V to 5.5V powered RS-232 transmitters (five)/receivers (three) which meet ElA/TIA-232 and V.28/V.24 specifications, even at V

= 3.0V. Additionally, they provide ±15kV ESD

protection (IEC61000-4-2 Air Gap) and Model protection on transmitter outputs and receiver inputs (RS-232 pins). Targeted applications are ISDN Terminal Adaptors, PDAs, Palmtops, peripherals, and notebook and laptop computers where the low operational, and even lower standby, power consumption is critical. The ICL3217E’s efficient on-chip charge pumps, coupled with an automatic powerdown function, reduces 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 250kbps are guaranteed at worst case load conditions. This family is fully compatible with 3.3V-only systems, mixed 3.3V and 5V systems, and 5V-only systems, and is a lower power, pin-for-pin replacement for ‘207E and ‘237E type devices.

The ICL3217E features an automatic powerdown function which powers down the on-chip power-supply and driver circuits. This occurs when an attached peripheral device is shut off or the RS-232 cable is removed, conserving system power automatically, without changes to the hardware or operating system. The ICL3217E powers up again when a valid RS-232 voltage is applied to any receiver input.

Table 1 summarizes the features of the devices represented by this data sheet, while application Note AN9863 summarizes the features of each device comprising the ICL32XXE 3V family.

NOTES:

1. Most surface mount devices are available on tape and reel; add “-T” to suffix.

2. Intersil Pb-free products employ special Pb-free material sets;

molding compounds/die attach materials and 100% matte tin plate termination finish, which is compatible with both SnPb and Pb-free soldering operations. Intersil Pb-free products are MSL classified at Pb-free peak reflow temperatures that meet or exceed the Pb-free requirements of IPC/JEDEC J Std-020B.
