description
TheSN751730triplelinedriver/receiverisspecificallydesignedtomeettheinput/outputinterfacespecifications
for IBM System 360/370. It is also compatible with standard TTL logic and supply voltage levels.
The low-impedance emitter-follower driver outputs of the SN751730 drive terminated lines such as coaxial
cable or twisted pair. Having the outputs uncommitted 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 2.5 V.
An open line affects the receiver input as does a low-level input voltage.
All the driver inputs and receiver outputs are in conventional TTL configuration and the gating can be used
during power-up and power-down sequences to ensure that no noise is introduced to the line by pulling either
DE1 or DE2 to a low level.

Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. These are stress ratings only, and
functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not
implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
