DESCRIPTION
The SN54ABT16244 and SN74ABT16244A are 16-bit
buffers and line drivers designed specifically to
improve both the performance and density of 3-state
memory address drivers, clock drivers, and
bus-oriented receivers and transmitters. These
devices can be used as four 4-bit buffers, two 8-bit
buffers, or one 16-bit buffer. These devices provide
true outputs and symmetrical OE (active-low
output-enable) inputs.
To ensure the high-impedance state during power up or power down, OE should be tied to VCC through a pullup
resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.
The SN54ABT16244 is characterized for operation over the full military temperature range of –55°C to 125°C.
The SN74ABT16244A is characterized for operation from –40°C to 85°C.

(1) Stresses beyond those listed under "absolute maximum ratings" may cause permanent damage to the device. These are stress ratings
only, and functional operation of the device at these or any other conditions beyond those indicated under "recommended operating
conditions" is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability
(2) The input and output negative-voltage ratings may be exceeded if the input and output clamp-current ratings are observed.
(3) The package thermal impedance is calculated in accordance with EIA/JEDEC Std JESD 51.

(1) Characteristics for TA = 25°C apply to the SN74ABT16244A only.
(2) All typical values are at VCC = 5 V.
(3) On products compliant to MIL-PRF-38535, this parameter does not apply.
(4) This data-sheet limit may vary among suppliers.
(5) Not more than one output should be tested at a time, and the duration of the test should not exceed one second.
(6) This is the increase in supply current for each input that is at the specified TTL voltage level rather than VCC or GND.

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.

-
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)
