FEATURES:
The IDT72V805 is equivalent to two IDT72V205 256 x 18 FIFOs
The IDT72V815 is equivalent to two IDT72V215 512 x 18 FIFOs
The IDT72V825 is equivalent to two IDT72V225 1,024 x 18 FIFOs
The IDT72V835 is equivalent to two IDT72V235 2,048 x 18 FIFOs
The IDT72V845 is equivalent to two IDT72V245 4,096 x 18 FIFOs
Offers optimal combination of large capacity (8K), high speed,
design flexibility, and small footprint
Ideal for the following applications:
– Network switching
– Two level prioritization of parallel data
– Bidirectional data transfer
– Bus-matching between 18-bit and 36-bit data paths
– Width expansion to 36-bit per package
– Depth expansion to 8,192 words per package
10 ns read/write cycle time
5V input tolerant
IDT Standard or First Word Fall Through timing
Single or double register-buffered Empty and Full Flags
Easily expandable in depth and width
Asynchronous or coincident Read and Write Clocks
Asynchronous or synchronous programmable Almost-Empty
and Almost-Full flags with default settings
Half-Full flag capability
Output enable puts output data bus in high-impedance state
High-performance submicron CMOS technology
Available in a 128-pin thin quad flatpack (TQFP)
Industrial temperature range (–40°C to +85°C) is available
DESCRIPTION:
The IDT72V805/72V815/72V825/72V835/72V845 are dual 18-bit-wide
synchronous (clocked) First-in, First-out (FIFO) memories designed to run
off a 3.3V supply for exceptionally low power consumption. One dual
IDT72V805/72V815/72V825/72V835/72V845 device is functionally equiva-
lent to two IDT72V205/72V215/72V225/72V235/72V245 FIFOs in a single
package with all associated control, data, and flag lines assigned to
independent pins. These devices are very high-speed, low-power First-In,
First-Out (FIFO) memories with clocked read and write controls. These
