SN74ACT72211L15RJ description

The SN74ACT72211L, SN74ACT72221L, SN74ACT72231L, and SN74ACT72241L are constructed withCMOS dual-port SRAM and are arranged as 512, 1024, 2048, and 4096 9-bit words, respectively. Internal writeand read address counters provide data throughput on a first-in, first-out (FIFO) basis. Full and empty flagsprevent memory overflow and underflow, and two programmable flags (almost full and almost empty) areprovided.The SN74ACT72211L, SN74ACT72221L, SN74ACT72231L, and SN74ACT72241L are synchronous FIFOs,which means the data input port and data output port each employ synchronous control. Write-enable (WEN1,WEN2/LD) signals allow the low-to-high transition of the write clock (WCLK) to store data in memory, andread-enable (REN1, REN2) signals allow the low-to-high transition of the read clock (RCLK) to read data frommemory. WCLK and RCLK are independent of one another and can operate asynchronously or be tied togetherfor single-clock operation.The empty-flag (EF) output is synchronized to RCLK and the full-flag (FF) output is synchronized to WCLK toindicate absolute boundary conditions. Write operations are prohibited when FF is low, and read operations areprohibited when EF is low. Two programmable flags, programmable almost empty (PAE) and programmablealmost full (PAF), can both be programmed to indicate any measure of memory fill. After reset, PAE defaultsto empty +7 and PAF defaults to full −7. Flag-offset programming control is similar to a memory write with theuse of the load (WEN2/LD) signal.These devices are suited for providing a data channel between two buses operating at asynchronous orsynchronous rates. Applications include use as rate buffers for graphics systems and high-speed queues forcommunication systems. A 9-bit-wide data path is provided for the transmission of byte data plus a parity bitor packet-framing information.The SN74ACT72211L, SN74ACT72221L, SN74ACT72231L, and SN74ACT72241L are characterized foroperation from 0°C to 70°C.
