MCM6706R
32K x 8 Bit Static Random Access
Memory
The MCM6706R is a 262,144 bit static random access memory organized as
32,768 words of 8 bits, fabricated using high performance silicon–gate BiCMOS
technology. Static design eliminates the need for external clocks or timing
strobes.
J PACKAGE
300 MIL SOJ
CASE 857–02
Output enable (G) is a special control feature that provides increased system
flexibility and eliminates bus contention problems.
The MCM6706R meets JEDEC standards and is available in a revolutionary
pinout 300 mil, 32–lead surface–mount SOJ package.

Power Supply Voltage
Voltage Relative to V
This device contains circuitry to protect the
inputs against damage due to high static volt-
ages or electric fields; however, it is advised
thatnormal precautions be taken to avoid appli-
cation of any voltage higher than maximum
rated voltages to this high–impedance circuit.
This BiCMOS memory circuit has been de-
signed 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
andtransverse air flow of at least500linearfeet
per minute is maintained.

NOTES:
1. W is high for read cycle.
2. Product sensitivities to noise require proper grounding and decoupling of power supplies as well as minimization or elimination of bus
contention conditions during read and write cycles.
3. All read cycle timing is referenced from the last valid address to the first transitioning address.
4. At any given voltage and temperature, t

5. Transition is measured 200 mV from steady–state voltage with load of Figure 1B.

TIMING LIMITS
The table of timing values shows either a
minimum or a maximum limit for each param-
eter. Input requirements are specified from
the external system point of view. Thus, ad-
dress setup time is shown as a minimum
since the system must supply at least that
much time (even though most devices do not
requireit). Ontheotherhand, responsesfrom
the memory are specified from the device
point of view. Thus, the access time is shown
as a maximum since the device never pro-
vides data later than that time.
