3 Description

These SNx4ACT244 octal buffers and drivers are

designed specifically to improve the performance and

density of 3-state memory address drivers, clock

drivers, and bus-oriented receivers and transmitters.

The SNx4ACT244 devices are organized as two 4-

bit buffers and drivers with separate output-enable

(OE) inputs. When OE is low, the device passes noninverted

data from the A inputs to the Y outputs.

When OE is high, the outputs are in the highimpedance

state.
