N74LS253N Datasheet
Notes: 1. During this period, l/0 pins are in the output state, so input signals of opposite phase to the outputs should not be applied 2. The data output from DOUT are the same as the data written to DIN during the write cycle. 3. Dout provides the read data for the next address. 4. Transition is measured +500 mV from steady state with CL = 5 pF. This parameter is guaranteed but not 100% tested.

The MU9C RCP is designed to act as an address translator for lookup tables in layer 2 switches. Refer to Figure 2 for a simplified block diagram of a switch. During normal operation, the controller extracts the address information from an arriving packet to form the comparand, which is then compared against the contents of the MU9C RCP. The MU9C RCP generates an index that is used to access the data in an external RAM, which holds the destination port for accessing the network. The controller reads the data from the RAM and forwards the packet.
