DESCRIPTION/
ORDERING INFORMATION
The SN751730 triple line driver/receiver is specifically
designed to meet the input/output interface
specifications for IBM System 360/370. It also is
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.

The marketing status values are defined as follows:
ACTIVE: Product device recommended for new designs.
LIFEBUY: TI has announced that the device will be discontinued, and a lifetime-buy period is in effect.
NRND: Not recommended for new designs. Device is in production to support existing customers, but TI does not recommend using this part in a new design.
PREVIEW: Device has been announced but is not in production. Samples may or may not be available.
OBSOLETE: TI has discontinued the production of the device.

RoHS: TI defines "RoHS" to mean semiconductor products that are compliant with the current EU RoHS requirements for all 10 RoHS substances, including the requirement that RoHS substance
do not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered at high temperatures, "RoHS" products are suitable for use in specified lead-free processes. TI may
reference these types of products as "Pb-Free".
RoHS Exempt: TI defines "RoHS Exempt" to mean products that contain lead but are compliant with EU RoHS pursuant to a specific EU RoHS exemption.
Green: TI defines "Green" to mean the content of Chlorine (Cl) and Bromine (Br) based flame retardants meet JS709B low halogen requirements of
