The MCM can be organized
as a 512K x 32 bits, 1M x 16
bits or 2M x 8 bits device and is
input and output TTL
compatible. Writing is executed
when the write enable (WE
and chip enable (CE

) inputs are
low. Reading is accomplished
when WE
output enable (OE

is high and CE and

) are both
low. Access time grades of
17ns, 20ns, 25ns, 35ns and
45ns maximum are standard.

The products are designed for
operation over the temperature
range of -55°C to +125°C and
screened under the full military
environment. DESC Standard
Military Drawing (SMD) part
numbers are pending.

The ACT-S512K32V is
