八路总线收发器、O.C.; • Bidirectional Bus Transceivers in High-Density 20-Pin Packages• Choice of True or Inverting Logic• Package Options Include Plastic Small-Outline (DW) Packagesand Standard Plastic (N) 300-mil DIPs;

These octal bus transceivers are designed for asynchronous two-way communication between\ndata buses. These devices transmit data from the A bus to the B bus or from the B bus to the A bus, depending upon the level at the direction-control (DIR) input. The output-enable input disables the device so that the buses are effectively isolated.\nThe -1 versions of the SN74ALS641A and SN74ALS642A are identical to the standard versions, except that the recommended maximum IOL is increased to 48 mA in the -1 versions.\nThe SN74ALS641A, SN74ALS642A, and SN74AS641 are characterized for operation from 0°C to 70°C.\n \n \n \n
