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
transmitters. Together with the SN54ABT2240,
SN74ABT2240A, and ’ABT2241, 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. These devices
feature high fan-out and improved fan-in.
receivers
and
The outputs, which are designed to sink up to 12 mA, include equivalent 25-
series resistors to reduce
overshoot and undershoot.
When V
CC
is between 0 and 2.1 V, the device is in the high-impedance state during power up or power down.
However, to ensure the high-impedance state above 2.1 V, 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 SN54ABT2244A is characterized for operation over the full military temperature range of –55
°
C to 125
°
C.
The SN74ABT2244A is characterized for operation from –40
