The SN74ACT3631-20PCB is a high-speed, low-power CMOS clocked FIFO memory with a capacity of 512 x 36 bits. It operates at clock frequencies up to 67 MHz and features fast access times of 11 ns. This dual-port SRAM FIFO allows for asynchronous or coincident clocking between its two ports, facilitating efficient data transfer from port A to port B. The device includes synchronous read-retransmit capability and features mailbox registers for communication between ports, along with programmable almost-full and almost-empty flags to monitor memory status. The input-ready and output-ready flags are synchronized to their respective clocks, enhancing operational reliability. The SN74ACT3631 is available in a 120-pin thin quad flat package and is characterized for operation within a temperature range of 0¬8C to 70¬8C. It is also pin-to-pin compatible with other models in the series, such as the SN74ACT3641 and SN74ACT3651, allowing for flexible design options.
