(TOP VIEW)

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 ′BCT240

and ′BCT241, 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 ′BCT244 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 SN54BCT244 is characterized for operation

over the full military temperature range of –55°C

to 125°C. The SN74BCT244 is characterized for

operation from 0°C to 70°C.
