+/- 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 VCC = 3.0V. Additionally, they provide ±15kV ESD protection (IEC 1000-4-2 Air Gap) and ±15kV Human Body 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.
