(VIO < VCC + 0.3V) 2) Caution in designing board lay-out To get maximum potential from RPM882-H14, please keep in mind following instruction. • The line of RXD (6pin) should be connected at backside via through hole close to RPM882-H14 pin lead. Better not to be close to photo diode side (1pin). ⇒This is to minimize feedback supplied to photo diode from RXD. • As for C1 between 1-3 pin should be placed close to RPM882-H14. • Better to be placed more than 1.0cm in radius from photo diode (pin1 side) and also away from the parts which generates noise, such as DC / DC converter. 3) Notes • Please be sure to set up the TX-RC (4pin) and the TXD (7pin) input to be “L” (under 0.3V) except transmitting data (for < 90µs, ON duty ≤ 50%). • Power down current might increase if exposed by strong light (ex. direct sunlight) at powerdown mode. • Please use by the signal format at IrDA operating mode which is specified by IrDA Ver1.2 (2.4k to 115.2kbps). There might be on error if used by different signal format. • Please pay attention to the lens carefully. Dusts of scratch on the lens may effect the characteristics of product.
