74ACT2708 64 x 9 First-In, First-Out Memory
General Description
The ACT2708 is an expandable first-in, first-out memory organized as 64 words by 9 bits. An 85 MHz shift-in and 60 MHz shift-out typical data rate makes it ideal for high-speed applications. It uses a dual port RAM architecture with pointer logic to achieve the high speed with negligible fallthrough time.
Separate Shift-In (SI) and Shift-Out (SO) clocks control the use of synchronous or asynchronous write or read. Other controls include a Master Reset (MR) and Output Enable (OE) for initializing the internal registers and allowing the data outputs to be 3-STATE.
