MCM6264C
1
Motorola, Inc. 1995
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 avail-
able 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
