Military product 100% compliant to MIL-STD-883,
Class B
DESCRIPTION:
The IDT6178 is a high-speed cache address comparator
sub-system consisting of a 16,384-bit StaticRAM organized
as 4K x 4. Cycle Time and Address to MATCH Valid are equal.
The IDT6178 features an onboard 4-bit comparator that
compares RAM contents and current input data. The result is
an active HIGH on the MATCH pin. The MATCH pins of
several IDT6178s can be handed together to provide enabling
or acknowledging signals to the data cache or processor.
The IDT6178 is fabricated using IDT’s high-performance,
high-reliability CMOS technology. Address to MATCH and
Data to MATCH times are as fast as 10ns.
All inputs and outputs of the IDT6178 are TTL-compatible
and the device operates from a single 5V supply.
The IDT6178 is packaged in either a 22-pin, 300-mil Plastic
or Ceramic DIP package or 24-pin SOJ. Military grade product
is manufactured in compliance with latest revision of MIL-
STD-883, Class B, making it ideally suited to military tempera-
ture applications demanding the highest level of performance
and reliability.
