ICL3207E, ICL3217E FN4914
Rev 6.00
August 21, 2015 +/-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 п‚±15kV ESD
protection (IEC61000-4-2 Air Gap) and п‚±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 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 5V systems, and
5V-only systems, and is a lower power, pin-for-pin …
