5120

× 8-bit Synchronous FIFO

OVERVIEW

The SM5838AS is a 5120

× 8-bit synchronous FIFO

(ﬁrst in, ﬁrst 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-

ﬁcation).

The SM5838AS can be used to easily realize a 1-line

delay in high-speed facsimile machines and digital

copiers.
