DM74AS245

This advanced Schottky device,DM74AS245, contains 8 pairs of 3-STATE logic elements configured as octal bus transceiv-ers. These DM74AS245 circuits are designed for use in memory, micro-processor systems and in asynchronous bidirectional data buses. Two way communication between buses is con-trolled by the (DIR) input. Data transmits either from the A bus to the B bus or from the B bus to the A bus. Both the driver and receiver outputs can be disabled via the (G) enable input which causes outputs to enter the high imped-ance mode so that the buses are effectively isolated.
