DESCRIPTION:
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,
RSB
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
Green parts available, see ordering information
The IDT72V805/72V815/72V825/72V835/72V845 are dual 18-bit-wide
