IMS1421C

The IMS1421C is a high performance 4K x 4 CMOS static RAM featuring fully static operation requiring no external clocks or timing strodes, and equal address access and cycle times.Additionally, it provides a chip select function which allows faster system access times to be achieved.

Features of the IMS1421C are:(1)INMOS very high speed CMOS; (2)advanced process-1.6 micron design rules; (3)4k x 4 bit organization; (4)high speed chip select function; (5)40 nsec address access time; (6)30nsec chip select access time; (7)fully TTL compatible; (8)three-state output; (9)20-pin,300-mil CDIP.

The absolute maximum ratings of the IMS1421C can be summarized as:(1): voltage on any pin relative to Vss is -2.0 V to 7.0 V; (2): temperature under bias is -55 to +125; (3): storage temperature(ambient) is -65 to 150; (4): power dissipation is 1 W; (5): DC output current is 25 mA.
