The UNIV-TTL Universal I/O module provides two TTL level output capable of driving a 50 ohm terminated line.
Output specifications are following:
| parameter | value | condition |
| connector type | LEMO EPK.00.250.NTN | |
| VOH | > 2.4 V | IOH= -48 mA |
| VOL | < 0.4 V | IOL= 48 mA |
Below is a scope screenshot of a TTL output pulse into 1.5 m of 50 ohm LEMO coaxial cable terminated with a 50 ohm load to ground.
