64K x 4 Fast Static RAM
The MCM6208C 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 Low Power Operation: 135 –165 mA Maximum AC Fully TTL Compatible — Three–State Output
