IDT72103, IDT72104
CMOS PARALLEL-SERIAL FIFO 2048 x 9, 4096 x 9
COMMERCIAL TEMPERATURE RANGES
DESCRIPTION (CONTINUED)
The IDT72103/72104 may be configured to handle serial
word widths of four or greater using IDT’s unique Flexishift
feature. Flexishift allows serial width and depth expansion
without external components. For example, you may config-
ure a 4K x 24 FIFO using three IDT72104s in a serial width
expansion configuration.
Seven flags are provided to signal memory status of the
FIFO. The flags are
FF
(Full),
AF
(7/8 full),
FF–1
(Full-minus-
one),
EF
(Empty),
AE
(1/8 full),
EF+1
(Empty-plus-one), and
HF
(Half-full).
Read (
R
) and Write (
W
) control pins are provided for
asynchronous and simultaneous operations. An output en-
able (
OE
) control pin is available on the parallel output port for
high-impedance control. The depth expansion control pins
XO
and
Xl
are provided to allow cascading for deeper FlFOs.
The IDT72103/72104 are manufactured using IDT’s CMOS
technology.
