Abstract
In this paper, we present the advanced open collector circuit, interface circuit between aerospace electronics. Satellite is composed of a number of electronics, which were provided from various manufacturers. Each company manufactured its own electronics for satellite using its heritage and requirements for their electronics. Therefore each electronics may use different internal supplies. It make a problem between electronics because the supply is different from other electronics, such as the increasing of power dissipation because of the static current and the mismatch of interface voltage, the offset. Proposed circuit can reduce the static current and rising time, and also decrease the useless power dissipation caused by the static current for open collector circuit
