in my one circuit i am interfacing one IC to FPGA which has 2.5 VCCIO. for that i am using ADG3308 IC in between FPGA and IC. IN data sheet of IC logic Input high current (Iih) is 20 uA(min.) to 100 uA(Max.).similarly logic output low current (Iol) is 4 mA minimum. but in ADG3308 IC Ioh & Iol is 20uA. Analog device suggest buffer after level translation ADG3308. Kindly tell buffer part no. i want to know whether we need to change voltage translator IC that support mA current drive for logic or this ADG will work. kindly suggest new IC if we require to change ADG3308 IC.
