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. Taken together with the
′
BCT241
and
′
BCT244, these devices provide the choice of
selected
combinations
noninverting outputs, symmetrical OE (active-low
output-enable) inputs, and complementary OE
and OE inputs. These devices feature high fan-out
and improved fan-in.
receivers
and
of
inverting
and
The
′
BCT240 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 SN54BCT240 is characterized for operation
over the full military temperature range of –55
°
C
to 125
°
C. The SN74BCT240 is characterized for
operation from 0
°
C to 70
°
C.
