Product Summary
These octal buffers and line drivers are designed specifically to improve both the performance and density of three-state memory address drivers,clock drivers, and bus-oriented receivers and transmitters. The designer has a choice of selected combinations of inverting and noninverting outputs, symmetrical, active-low output-control (G) inputs, and complementary output-control (G and G) inputs.
Parametrics
absolute maximum ratings: (1)Supply voltage, VCC (see Note 1):7 V; (2)Input voltage, VI: 'LS:7 V;'S:5.5 V; (3)Off-state output voltage:5.5 V; (4)Package thermal impedance, θJA (see Note 2): DB package:7℃/W;DW package:58℃/W;N package:69℃//W;NS package:60℃/W; (5)Storage temperature range, Tstg :–65℃ to 150℃
Features
