Rev 9.00
October 5, 2015 1 Microamp, +3V to +5.5V, 1Mbps, RS-232 Transceivers with Enhanced
Automatic Powerdown
The Intersil ICL32XX devices are 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 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 and enhanced
automatic powerdown functions, reduce 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 1Mbps 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 ICL3245 is a 3 driver, 5 receiver device that provides a
complete serial port suitable for laptop or notebook
computers. It also includes a noninverting always-active
receiver for “wake-up” capability. Features п‚±15kV ESD Protected (Human Body Model) Manual and Enhanced Automatic Powerdown Features Drop in Replacements for MAX3225, MAX3245 Meets EIA/TIA-232 and V.28/V.24 Specifications at 3V Latch-Up Free On-Chip Voltage Converters Require Only Four External …
