description
All other input combinations
The SN75ALS123 dual line driver is specifically
H = high level L = low level
X = irrelevant
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.

Eco Plan
-
The planned eco-friendly classification: Pb-Free (RoHS) or Green (RoHS
&
no Sb/Br)
-
please check
http://www.ti.com/productcontent for the latest availability information and additional product content details.
TBD: The Pb-Free/Green conversion plan has not been defined.
Pb-Free (RoHS): TI's terms "Lead-Free" or "Pb-Free" mean semiconductor products that are compatible with the current RoHS requirements
for all 6 substances, including the requirement that lead not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered
at high temperatures, TI Pb-Free products are suitable for use in specified lead-free processes.
Green (RoHS & no Sb/Br): TI defines "Green" to mean Pb-Free (RoHS compatible), and free of Bromine (Br) and Antimony (Sb) based flame
retardants (Br or Sb do not exceed 0.1% by weight in homogeneous material)
