ICL3237
1 Microamp Supply-Current, +3V to +5.5V,
1Mbps, RS-232 Transmitters/Receivers
The Intersil ICL3237 contains 3.0V to 5.5V powered RS-232
transmitters/receivers which meet ElA/TIA-232 and
V.28/V.24 specifications, even at VCC = 3.0V. Targeted
applications are cell phones, PDAs, Palmtops, and notebook
and laptop computers where the low operational, and even
lower standby, power consumption is critical. Efficient on-
chip charge pumps, coupled with manual powerdown
function, reduce the standby supply current to a 1
A trickle.
Small footprint packaging, and the use of small, low value
capacitors ensure board space savings as well. Data rates
greater than 1Mbps (MBAUD = VCC) 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.
The ICL3237 is a 5 driver, 3 receiver device that also
includes a noninverting always-active receiver for “wake-up”
capability.
Table 1 summarizes the features of the device represented
by this data sheet, while Application Note AN9863
summarizes the features of each device comprising the
ICL32XX 3V family.
