IDT72T36115 Integrated Device Technology, IDT72T36115 Datasheet - Page 46

• Manufacturer Part Number: IDT72T36115
• Description: 128k X 36 Terasync Fifo, 2.5v - Best Value!
• Manufacturer: Integrated Device Technology

NOTE:
1. X = 10 for the IDT72T3645, X = 11 for the IDT72T3655, X = 12 for the IDT72T3665, X = 13 for the IDT72T3675, X = 14 for the IDT72T3685, X = 15 for the IDT72T3695, X = 16
NOTE:
1. This timing diagram illustrates programming with an input bus width of 36 bits.
NOTES:
1. OE = LOW.
2. The timing diagram illustrates reading of offset registers with an output bus width of 36 bits.
3. The offset registers cannot be read on consecutive RCLK cycles. The read must be disabled (REN = HIGH) for a minimum of one RCLK cycle in between register accesses.
