COMMERCIAL SWITCHING CHARACTERISTICS AND WAVEFORMS

In the switching waveforms that follow, several abbre-

viations are used to indicate the specific periods of a

bus cycle. These periods are referred to as time states.

A typical bus cycle is composed of four consecutive

time states: t1, t2, t3, and t4. Wait states, which represent

multiple t3 states, are referred to as tw states. When no bus

cycle is pending, an idle (ti) state occurs.

In the switching parameter descriptions, the

multi-

plexed address is referred to as the AD address bus; the

demultiplexed address is referred to as the A address

bus.
