LM55121
LM55121 is dual line drivers manufactured by National Semiconductor.
description features
:E The LM55121/LM75121 are monolithic dual line
....I drivers designed to drive long lengths of coaxial cable, strip line, or twisted pair transmission lines
- Designed for digital data transmission over 50 to 500 ohms coaxial cable, strip line, or twisted pair transmission lines having impedances from 50 to 500 ohms. Both are patible with standard TTL logic and
- TTL patible supply voltage levels.
- Open emitter-follower output structure for
The LM55121/LM75121 will drive terminated low party-line operation impedance lines due to the low- impedance emitter- follower outputs. In addition the outputs are
- Short-circuit protection unmitted allowing two or more drivers to drive the same line.
- AND-OR logic configuration
Output short-circuit protection is incorporated
- High speed (max propagation delay time 20 ns) to...
