The Renesas Electronics is a 3.0V to 5.5V powered,±15kV ESD Protected, 1Microamp, 250kbps,RS‑232 transceiver that meets ElA/TIA-232 and V.28/V.24 specification. targeted applications are industrial laptop computers, Palmtops, PDAs, and notebooks where the low operational power consumption and even lower standby power consumption is critical. efficient on‑chip charge pumps coupled with manual and enhanced automatic powerdown functions which reduce the standby supply current to a 1μA trickle. its power back up done by automatically, when it senses a transition on any transmitter or receiver input.

VL supply pin for compatibility with mixed voltage systems
On-chip charge pumps require only four external 0.1μF capacitors
Very low supply current
Assured minimum data rate
Wide power supply range
Low supply current in power down state
