64K x 4 Bit Fast Static RAM
With Output Enable
The MCM6209C 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: 135 – 165 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.
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.
