... Capable of withstanding greater than 2001V electro- static discharge voltage • 300-mil, 28-pin DIP Functional Description The CY7C408A and CY7C409A are 64-word deep 9-bit wide first-in first-out (FIFO) buffer memories. In addition to the industry-standard handshaking signals, almost full/al- most empty (AFE) and half-full (HF) flags are provided. ...
