SN75121 Datasheet DUAL LINE DRIVERS

Manufacturer: Texas Instruments

Overview: D Designed for Digital Data Transmission Over 50-Ω to 500-Ω Coaxial Cable, Strip Line, or Twisted Pair D High Speed tpd = 20 ns Maximum at CL = 15 pF D TTL Compatible With Single 5-V Supply D 2.

General Description

The SN55121 and SN75121 dual line drivers are designed for digital data transmission over lines having impedances from 50 to 500 Ω.

They are also compatible with standard TTL logic and supply-voltage levels.

The low-impedance emitter-follower outputs of the SN55121 and SN75121 can drive terminated lines such as coaxial cable or twisted pair.
