description
This octal buffer and line driver is designed
specifically to improve both the performance and
density of 3-state memory address drivers, clock
drivers, and bus-oriented receivers and
transmitters. The SN74BCT756, SN74BCT757,
and SN74BCT760 provide the choice of selected
combinations of inverting outputs, symmetrical
output-enable (OE) inputs, and complementary
OE and OE inputs.
The SN74BCT756 is characterized for operation
from 0°C to 70°C.
