Description
The V53C16258SH is a high speed 262,144 x 16
bit high performance CMOS dynamic random
access memory. The V53C16258SH offers a
combination of unique features including: EDO
Page Mode operation for higher sustained
bandwidth with Page Mode cycle times as short as
19ns. All inputs are TTL compatible. Input and
output capacitance is significantly lowered to
increase performance and minimize loading. These
features make the V53C16258SH ideally suited for
a wide variety of high performance computer
systems and peripheral applications.
