2149H

The 2149H is designed as 1.24 X 4-bit static RAM with max address access time of 35ns and max chip select access time of 20ns and max active current of 150mA.

2149H has many features. The first one is it would have improved performance margins. The next one is it has fast chip select access time which would be max 20ns. The next one is equil access and cycle times. The next one is it would be available in EXPRESS which would be standard temperature range and extended temperature range. The next one is it would use HMOS III technology. The next one is common data input and output. The next one is it would have three-state output. The next one is single +5V supply. The next one is automatic power-down 2148H available. The next one is 2149H would have high reilability plastic or CERDIP package. That are all the main features.

Some absolute maximum ratings of 2149H have been concluded into several points as follow. The first one is about its temperature under bias which would be from -10°C to +85°C. The next one is about its storage temperature CERDIP which would be from -65°C to +150°C. The next one is about its storage temperature plastic which would be from -65°C to +125°C. The next one is about its voltage on any pin with respect to ground which would be from -3.5V to +7V. The next one is about its DC continuous output current which would be 20mA. The next one is about its power dissipation which would be 1.2W. 2149H should be noted that stresses above those listed under "absolute maximum ratings" may cause permanent damage to the device. This is a stress rating only and function operation of the device at these or any other conditions above those indicated in the operational sections of this specification is not implied. And so on.
