description
The 74ACT11623 is designed for asynchronous two-way communication between data buses. The control
function implementation allows for maximum flexibility in timing.
The device allows data transmission from the A bus to the B bus or from the B bus to the A bus depending upon
the logic levels at the enable inputs (GBA and GAB). The enable inputs can be used to disable the device so
that the buses are effectively isolated.
The dual-enable configuration gives these devices the capability to store data by simultaneous enabling of GBA
and GAB. Each output reinforces its input in this transceiver configuration. Thus, when both control inputs are
enabled and all other data sources to the two sets of bus lines are at high impedance, both sets of bus lines (16
in all) will remain at their last states. The 8-bit codes appearing on the two sets of buses will be identical for the
74ACT11623.
The 74ACT11623 is characterized for operation from – 40°C to 85°C.

(1) 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.
(2)
Eco Plan - The planned eco-friendly classification: Pb-Free (RoHS), Pb-Free (RoHS Exempt), 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.
Pb-Free (RoHS Exempt): This component has a RoHS exemption for either 1) lead-based flip-chip solder bumps used between the die and
package, or 2) lead-based die adhesive used between the die and leadframe. The component is otherwise considered Pb-Free (RoHS
compatible) as defined above.
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)
(3)
MSL, Peak Temp. -- The Moisture Sensitivity Level rating according to the JEDEC industry standard classifications, and peak solder
