GENERAL DESCRIPTION
The 74HC/HCT7403 are high-speed
Si-gate CMOS devices. They are
specified in compliance with JEDEC
standard no.7A.
The “7403” is an expandable, First-In
First-Out (FIFO) memory organized
as 64 words by 4 bits. A guaranteed
15 MHz data-rate makes it ideal for
high-speed applications. A higher
data-rate can be obtained in
applications where the status flags
are not used (burst-mode).
With separate controls for shift-in (SI)
and shift-out (SO), reading and
writing operations are completely
independent, allowing synchronous
and asynchronous data transfers.
Additional controls include a
master-reset input (MR), an output
enable input (OE) and flags. The
data-in-ready (DIR) and
data-out-ready (DOR) flags indicate
the status of the device.
