General Description

: The IDT73720/A Bus Exchanger is a high speed 16-bit bus exchange device intended for inter-bus communication in interleaved memory systems and high performance multiplexed address and data busses.

The Bus Exchanger is responsible for interfacing between the CPU A/D bus (CPU address/data bus) and multiple memory data busses.

The 73720/A uses a three bus architecture (X, Y, Z), with control signals suitable for simple transfer between the CPU bus (X) and either memory bus (Y or Z).
