need help @ MAX1840 ??

Hi
Im using MAX1840 level translator between two controllers. But im facing some problem with default status of the translator. Data pin is always pulled high because internal 10K pull resistor of 1840. But RIN(Reset In) and CIN (CLK In) pins are always at 2 - 2.4 V. Im keeping Dvcc @ 3.3 V and Vcc @ 2.8 V.
I verified if controller is driving on 1840 but that is not the case. Can anyone tell me what should be status of the 1840 pins.
~niks~

I have no past experience with 1840... But...

RIN: to ground,
CLKIN: See data sheet of this device... you can control internal clock or suply it from external clk to keep syncronization. this dependes on the construction of this IC
DIN: is the serial data stream!!! isn't it??

I think you should read datasheet for exact explenations
