Overview: ISL83239E POSSIOBLBESOSLUICEBLTS3ET2IP3TR8UEOTEDUPCRTODUCT ±15kV ESD Protected, 10nA Supply-Current, +3V to +5.5V, 250kbps, RS-232 Transmitters/Receivers DATASHEET
FN6015 Rev 3.00 June 2004 The Intersil ISL83239E 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 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, PDAs, Palmtops, and data cables where the low operational, and even lower standby, power consumption is critical. Efficient on-chip charge pumps, coupled with the manual powerdown function, 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.
The ISL83239E is a 5 driver, 3 receiver device that also includes a noninverting always-active receiver for “wake-up” capability.
