UT62256PC-70LL DIP-28

32K X 8 BIT LOW POWER CMOS SRAM

GENERAL DESCRIPTION
The UT62256 is a 262,144-bit low power
CMOS static random access memory
organized as 32,768 words by 8 bits. It is
fabricated using high performance, high
reliability CMOS technology.
The UT62256 is designed for high-speed and
low power application. It is particularly well
suited for battery back-up nonvolatile memory
application.
The UT62256 operates from a single 5V
power supply and all inputs and outputs are
fully TTL compatible
