Description

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 andinputs. 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.
