The SN74ACT3622 is a clocked bidirectional FIFO memory with a capacity of 256 x 36 bits, designed for high-speed and low-power applications. It operates at clock frequencies up to 67 MHz and features fast access times of 11 ns. This device includes two independent FIFOs that buffer data in opposite directions, each equipped with programmable almost-full and almost-empty flags, as well as mailbox-bypass registers for direct communication. The FIFO's input and output flags are synchronized to their respective port clocks, allowing for efficient data transfer. The SN74ACT3622 is characterized for operation within a temperature range of 0°C to 70°C and is available in a 132-pin plastic quad flat package. It is pin-to-pin compatible with similar devices in the series, making it suitable for applications requiring flexible data path configurations.
