8K x 8 Bit Fast Static RAM
The MCM6264C is fabricated using Motorola's high-performance silicon-gate CMOS technology. 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 dual-in-line and plastic small-outline J-leaded packages. Single 5 V 10% Power Supply Fully Static -- No Clock or Timing Strobes Necessary Fast Access Times: 12, 15, 20, 25, and 35 ns Equal Address and Chip Enable Access Times Output Enable (G) Feature for Increased System Flexibility and to Eliminate Bus Contention Problems * Low Power Operation: 110 - 150 mA Maximum AC * Fully TTL Compatible -- Three State Output * * * * *

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.
Storage Temperature -- Plastic Tstg - 55 to + 125 C NOTE: Permanent device damage may occur if ABSOLUTE MAXIMUM RATINGS are exceeded. Functional operation should be restricted to RECOMMENDED OPERATING CONDITIONS. Exposure to higher than recommended voltages for extended periods of time could affect device reliability.

NOTES: 1. W is high for read cycle. 2. E1 and E2 are represented by E in this data sheet. E2 is of opposite polarity to E. 3. All timings are referenced from the last valid address to the first transitioning address. 4. Addresses valid prior to or coincident with E going low. 5. At any given voltage and temperature, tEHQZ (max) is less than tELQX (min), and tGHQZ (max) is less than tGLQX (min), both for a given device and from device to device. 6. Transition is measured 500 mV from steady-state voltage with load of Figure 1B. 7. This parameter is sampled and not 100% tested. 8. Device is continuously selected (E1 = VIL, E2 = VIH, G = VIL).

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 (even though most devices do not require it). 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.
