description
The SN751730 triple line driver/receiver is specifically designed to meet the input/output interface specifications
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.
