32K x 8 Bit Fast Static RAM
The MCM6206BB is a 262,144 bit static random access memory organized as
32,768 words of 8 bits. Static design eliminates the need for external clocks or
timing strobes, while CMOS circuitry reduces power consumption and provides
for greater reliability .
This device meets JEDEC standards for functionality and pinout, and is available in plastic small–outline J–leaded packages.

This device contains circuitry to protect the
inputs against damage due to high static voltages or electric fields; however, it is advised
that normal precautions be taken to avoid
application of any voltage higher than maximum rated voltages to this high–impedance
circuit.
This CMOS memory circuit has been designed to meet the dc and ac specifications
shown in the tables, after thermal equilibrium
has been established. The circuit is in a test
socket or mounted on a printed circuit board
and transverse air flow of at least 500 linear
feet per minute is maintained.

TIMING LIMITS
The table of timing values shows either a
minimum or a maximum limit for each parameter. Input requirements are specified from
the external system point of view. Thus, address setup time is shown as a minimum
since the system must supply at least that
much time. On the other hand, responses
from the memory are specified from the device point of view. Thus, the access time is
shown as a maximum since the device never
provides data later than that time.
