54ACT16623, 74ACT16623 16-BIT BUS TRANSCEIVERS WITH 3-STATE OUTPUTS SCAS152A – JANUARY 1991 – REVISED APRIL 1996 D D D D D D Members of the Texas Instruments Widebus Family Inputs are TTL-Voltage Compatible Flow-Through Architecture Optimizes PCB Layout Distributed VCC and GND Pin Configuration Minimizes High-Speed Switching Noise EPIC (Enhanced-Performance Implanted CMOS) 1-µm Process Package Options Include Plastic 300-mil Shrink Small-Outline (DL) Packages Using 25-mil Center-to-Center Pin Spacings and 380-mil Fine-Pitch Ceramic Flat (WD) Packages Using 25-mil Center-to-Center Pin Spacings description The ’ACT16623 are 16-bit transceivers designed for asynchronous two-way communication between data buses. The control-function implementation allows for maximum flexibility in timing. These devices can be used as two 8-bit transceivers or one 16-bit transceiver. They allow data transmission from the A bus to the B bus or from the B bus to the A bus, depending on the logic level at the output-enable (OEBA and OEAB) inputs. The output-enable inputs can be used to disable the device so that the buses are effectively isolated. 54ACT16623 . . . WD PACKAGE 75ACT16623 . . .

Each output reinforces its input in this transceiver configuration. When both control inputs are enabled and all other data sources to the two sets of bus lines are at high impedance, the bus lines remain at their last states. The 74ACT16623 is packaged in TI’s shrink small-outline package, which provides twice the functionality of standard small-outline packages in the same printed-circuit-board area. The 54ACT16623 is characterized for operation over the full military temperature range of –55°C to 125°C. The 74ACT16623 is characterized for operation from –40°C to 85°C.

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 temperature.
