description  
The SN74ACT7807 is a 2048-word by 9-bit FIFO with high speed and fast access times. It processes data at  
rates up to 67 MHz and access times of 12 ns in a bit-parallel format. Data outputs are noninverting with respect  
to the data inputs. Expansion is easily accomplished in both word width and word depth.  
The write-clock (WRTCLK) and read-clock (RDCLK) inputs should be free running and can be asynchronous  
or coincident. Data is written to memory on the rising edge of WRTCLK when the write-enable (WRTEN1/DP9,  
WRTEN2) inputs are high and the input-ready (IR) flag output is high. Data is read from memory on the rising  
edge of RDCLK when the read-enable (RDEN1, RDEN2) and output-enable (OE) inputs are high and the  
output-ready (OR) flag output is high. The first word written to memory is clocked through to the output buffer  
regardless of the levels on RDEN1, RDEN2, and OE. The OR flag indicates that valid data is present on the  
output buffer.  
The FIFO can be reset asynchronous to WRTCLK and RDCLK. RESET must be asserted while at least four  
WRTCLK and four RDCLK cycles occur to clear the synchronizing registers. Resetting the FIFO initializes the  
IR, OR, and half-full (HF) flags low and the almost-full/almost-empty (AF/AE) flag high. The FIFO must be reset  
upon power up.  
The SN74ACT7807 is characterized for operation from 0°C to 70°C.
