I need to build circuits for level translation between NIM logic (fast negative) and TTL. Once upon a time, LeCroy sold such a NIM module but they are long gone.
One idea is to start with existing ICs that translate between TTL and ECL and go from there.
For NIM -> TTL, it appears that the MC10H125 Quad MECL-to-TTL translator might work directly since it has differential inputs.
For TTL -> NIM, the MC10H124 Quad TTL-to-MECL outputs would need to be converted to NIM. Someone has suggested a line driver, but this part I am not clear on.
The eventual PCB will need to contain four TTL -> NIM and four NIM -> TTL circuits. Any suggestions?
