Description
The V62C5181024 is a 1,048,576-bit static
random-access memory organized as 131,072
words by 8 bits. It is built with MOSEL VITELIC’s
high performance CMOS process. Inputs and
three-state outputs are TTL compatible and allow
for direct interfacing with common system bus
structures.

chip enables must be active to read from or write to
the device. If either chip enable is not active, the
device is deselected and is in a standby power
mode. The I/O pins will be in the high-impedance
state when deselected.
OE
The Output Enable input is active LOW. When OE
is LOW with CE LOW and WE HIGH, data of the
selected memory location will be available on the
I/O pins. When OE is HIGH, the I/O pins will be in
the high impedance state.
