NOTES:
1. Since the FIFO is a very high-speed device, care must be excercised in the design of the hardware and timing utilized within the design. Device grounding and decoupling
are crucial to correct operation as the FIFO will respond to very small glitches due to long reflective lines, high capacitances and/or poor supply decoupling and grounding.
A monolithic ceramic capacitor of 0.1μF directly between VCC and GND with very short lead length is recommended.
2. This parameter applies to FIFOs communicating with each other in a cascaded mode. IDT FIFOs are guaranteed to cascade with other IDT FIFOs of like speed grades.
3. IDT72403 only.
4. Guaranteed by design but not currently tested.
5. Military availability for IDT72403 is 10MHz, 35MHz. IDT72401 is available for all MHz.
