Direct interfacing to most microprocessor busses is
easily accomplished through the three-state output of the
TC7109A.
Figures 1, 17 and 18 are typical connection diagrams.
To ensure requirements for setup and hold times, minimum
pulse widths, and the drive limitations on long busses are
met, it is necessary to carefully consider the system timing
in this type of interface. This type of interface is used when
the memory peripheral address density is low, providing
simple address decoding. Interrupt handling can be simpli-
fied by using an interface to reduce the component count.
