Features

◆

width to 36 bits (32 bits) or more using the Master/Slave

select when cascading more than one device

M/S = VIH for BUSY output flag on Master

M/S = VIL for BUSY input on Slave

BUSY and Interrupt Flag

On-chip port arbitration logic

True Dual-Ported memory cells which allow simultaneous

reads of the same memory location

High-speed access

◆

NOTES:

1. A12 is a NC for IDT70T34 and IDT70T24.

2. (MASTER): BUSY is output; (SLAVE): BUSY is input.

3. BUSY outputs and INT outputs are non-tri-stated push-pull.

4. I/O0x - I/O7x for IDT70T25/24.

5. I/O8x - I/O15x for IDT70T25/24.
