ICL3207, ICL3217 FN4892
Rev 7.00
August 21, 2015 Low Power, +3V to +5.5V, 250kbps, RS-232 Transmitters/Receivers
The Intersil ICL32X7 devices are 3.0V 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. 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 ICL3217’s
efficient on-chip charge pumps, coupled with an automatic
powerdown function, reduces the standby supply current to
a 1пЃ­A 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 5.0V systems, and
5.0V only systems, and is a lower power, pin-for-pin
replacement for �207 and �237 type devices.
The ICL3217 features an automatic powerdown function
which powers down the on-chip power-supply and driver
circuits. This occurs when an attached peripheral device is …
