IDT7133 IDT [Integrated Device Technology], IDT7133 Datasheet - Page 15

• Manufacturer Part Number: IDT7133
• Description: HIGH-SPEED 2K x 16 CMOS DUAL-PORT STATIC RAMS
• Manufacturer: IDT [Integrated Device Technology]

NOTES:
1. Pins BUSY
2. "L" if the inputs to the opposite port were stable prior to the address and enable
3. Writes to the left port are internally ignored when BUSY
NOTES:
1. A
2. If BUSY = LOW, data is not written.
3. If BUSY = LOW, data may not be valid, see t
4. "H" = HIGH, "L" = LOW, "X" = Don’t Care, "Z" = High-Impedance, "LB" = Lower Byte, "UB" = Upper Byte
