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. Together with the SN54ABT2240,
SN74ABT2240A and ’ABT2244A, 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.
The outputs, which are designed to sink up to
12 mA, include equivalent 25-W series resistors to
reduce overshoot and undershoot.
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. OE
should be tied to GND through a pulldown resistor; the minimum value of the resistor is determined by the
current-sourcing capability of the driver.
The SN54ABT2241 is characterized for operation over the full military temperature range of –55°C to 125°C.
The SN74ABT2241 is characterized for operation from –40°C to 85°C.
