description/ordering information
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 SN74BCT2241
and the ’BCT2244 devices, 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 ’BCT2240 devices are organized as two 4-bit
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.
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 outputs, which are designed to source or sink up to 12 mA, include 33-
series resistors to reduce overshoot
and undershoot.
