UT61256C
32K X 8 BIT HIGH SPEED CMOS SRAM
The UT61256C is a 262,144-bit high-speed
CMOS static random access memory organized
as 32,768 words by 8 bits. It is fabricated using
high performance, high reliability CMOS
technology.
The UT61256C is designed for high-speed
system applications. It is particularly suited for
use in high-density high-speed system
applications.
The UT61256C operates from a single 5V power
supply and all inputs and outputs are fully TTL
compatible.
