description

The SN75ALS123 dual line driver is specifically designed to meet the input interface specifications for the IBM System 360. It is compatible with standard TTL logic and supply voltage levels. The low-impedance, emitter-follower outputs drive terminated lines such as coaxial cable, strip line, or twisted pair. The uncommitted output allows wired-OR logic to be performed in party-line applications. Output short-circuit protection is provided by an internal clamping network that turns on when the output voltage drops below approximately 1.5 V. All inputs are in conventional TTL configuration. Gating can be used during power-up and power-down sequences to ensure that no noise is introduced on the line.

The SN75ALS123 employs the IMPACT^TM process to achieve fast switching speeds, low power dissipation, and reduced input current requirements.

The SN75ALS123 is characterized for operation from 0°C to 70°C.
