5120
脳
8-bit Synchronous FIFO
OVERVIEW
The SM5838AS is a 5120
脳
8-bit synchronous FIFO
(铿乺st in, 铿乺st out) high-speed line buffer. Internally, it
employs static CMOS circuits which mean that it
effectively has limitless data hold times. It can oper-
ate at speeds up to 33.3 MHz (normal-voltage speci-
铿乧ation).
The SM5838AS can be used to easily realize a 1-line
delay in high-speed facsimile machines and digital
copiers.
