description
These octal buffers and line drivers are designed
specifically to improve both the performance and
density of 3-state memory address drivers, clock
drivers,
and
bus-oriented
receivers
and
transmitters. Taken together with the
′F240 and
′F241, these devices provide the choice of
selected
combinations
of
inverting
and
noninverting outputs, symmetrical OE (active-low
output-enable) inputs, and complementary OE
and OE inputs.
The
′F244 is organized as two 4-bit buffers/line
drivers with separate output enable (OE) inputs.
When OE is low, the device passes data from the
A inputs to the Y outputs. When OE is high, the
outputs are in the high-impedance state.
The SN74F244 is available in TI’s shrink
small-outline package (DB), which provides the
same I/O pin count and functionality of standard
small-outline packages in less than half the
printed-circuit-board area.
The SN54F244 is characterized for operation over
the full military temperature range of 55
°C to
125
°C. The SN74F244 is characterized for
operation from 0
°C to 70°C.
