SN74AS757 に関する概要
These octal buffers and line drivers are designed specifically to
improve the performance and density of 3-state memory address
drivers, clock drivers, and bus-oriented receivers and transmitters
by eliminating the need for 3-state overlap protection. The designer
has a choice of selected combinations of inverting and noninverting
outputs, symmetrical active-low output-enable (
) inputs, and complementary OE and
inputs. These
devices feature high fan-out and improved fan-in.
The SN54AS756 is characterized for operation over the full military temperature range of -55°C to 125°C. The SN74AS756 and SN74AS757 are characterized for operation from 0°C to 70°C.
