The Intersil ISL324xE devices are 2.7V to 3.6V powered
RS-232 transmitters/receivers which meet ElA/TIA-232 and
V.28/V.24 specifications, even at VCC = 3.0V. Additionally,
they provide ±15kV ESD protection (IEC61000-4-2 Air Gap
and Human Body Model) on transmitter outputs and receiver
inputs (RS-232 pins). Targeted applications are POS
systems, 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 automatic power-down functions, reduce the standby
supply current to a 0.5μA trickle. Tiny 5mmx5mm Quad Flat
No-Lead (QFN) 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.
ISL324xE are 3 driver, 5 receiver devices that, coupled with
the 5x5 QFN package, provide the industry’s smallest,
lowest power complete serial port. The 5x5 QFN requires
60% less board area than a 28 Ld TSSOP, and is nearly
20% thinner. These devices also include a noninverting
always-active receiver for “wake-up” capability.
