Dual chip enables allow for depth expansion without
external logic
IDT7008 easily expands data bus width to 16 bits or
more using the Master/Slave select when cascading more
than one device
M/S = V
IH
for

NOTES:
1.
BUSY
is an input as a Slave (M/S = V
IL
) and an output when it is a Master (M/S = V
IH
).
2.
BUSY
and
INT
are non-tri-state totem-pole outputs (push-pull).
