Using Machine Model (C = 200 pF, R = 0)
(1) Component qualification in accordance with JEDEC and
industry standards to ensure reliable operation over an
extended temperature range. This includes, but is not limited
to, Highly Accelerated Stress Test (HAST) or biased 85/85,
temperature cycle, autoclave or unbiased HAST,
electromigration, bond intermetallic life, and mold compound
life. Such qualification testing should not be viewed as
justifying use of this component beyond specified
performance and environmental limits.

DESCRIPTION
This octal buffer and line driver is designed specifically to improve both the performance and density of 3-state
memory address drivers, clock drivers, and bus-oriented receivers and transmitters. Together with the
SN54ABT240, SN74ABT240A, SN54ABT241, and SN74ABT241A, these devices provide the choice of selected
combinations of inverting and noninverting outputs, symmetrical active-low output-enable (OE) inputs, and
complementary OE and OE inputs.
The SN74ABT244A is organized as two 4-bit buffers/line drivers with separate OE inputs. When OE is low, the
device passes noninverted data from the A inputs to the Y outputs. When OE is high, the outputs are in the
high-impedance state.
To ensure the high-impedance state during power up or power down, OE should be tied to V_CC through a pullup
resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.
The SN74ABT244 is characterized for operation over the full military temperature range of –55°C to 125°C.
