八路缓冲器及其与集电极开路输出线路驱动器 OCTAL BUFFERS AND LINE DRIVERS WITH OPEN-COLLECTOR OUTPUTS
description
These octal buffers and line drivers are designed specifically to improve both 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. With the ′AS756 and SN74AS757, these devices provide the choice of selected combinations of inverting outputs, symmetrical active-low output-enable OE inputs, and complementary OE and OE inputs.
The SN54AS760 is characterized for operation over the full military temperature range of −55°C to 125°C. The SN74ALS760 and SN74AS760 are characterized for operation from 0°C to 70°C.
• Open-Collector Outputs Drive Bus Lines or Buffer Memory Address Registers
