NOTES:
1. BUSY is an input as a Slave (M/S=V
2. BUSY and INT are non-tri-state totem-pole outputs (push-pull).
True Dual-Ported memory cells which allow simultaneous
access of the same memory location
High-speed access
– Commercial: 15/20ns (max.)
– Industrial: 20ns (max.)
Low-power operation
– IDT70V18L
Dual chip enables allow for depth expansion without
external logic
IDT70V18 easily expands data bus width to 18 bits or
more using the Master/Slave select when cascading more
than one device
