DATASHEET
ICL3238E FN6012
Rev 3.00
July 2004 В±15kV ESD Protected, +3V to +5.5V, 10nA, 250kbps, RS-232 Transceiver with
Enhanced Automatic Powerdown
The Intersil ICL3238E 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. Additionally, it
provides п‚±15kV ESD protection (IEC61000-4-2 Air Gap and
Human Body Model) on transmitter outputs and receiver
inputs (RS-232 pins). Targeted applications are cell phones,
Palmtops, and data cables 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 10nA 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 providing
compatibility with popular PC communication software. Features Pb-Free Available as an Option (see Ordering Info) ESD Protection for RS-232 I/O Pins to п‚±15kV (IEC61000) Active Feedback Resistors on TX and Logic Inputs. Manual and Enhanced Automatic Powerdown Features Pin Compatible Replacement for MAX3238E, MAX3238,
SP3238E Meets EIA/TIA-232 and V.28/V.24 Specifications at 3V RS-232 Compatible Outputs at 2.7V Supply Flow Through Pinout Latch-Up Free The ICL3238E is a 5 driver, 3 receiver device optimized for
DCE applications with full hardware handshaking. It also
includes a noninverting always-active receiver for RING …
