ttl circuit造句

• Specification for harmonized system of quality assessment for electronic components - family specification : digital integrated ttl circuits series 54 , 64 , 74 , 84
  电子元器件质量评定协调体系规范.系列规范:数字集成ttl电路系列54 64 74 84
• In the design , we make use of the two powerful eda tools of max + plus ii and protel1 99 . using max + plus ii to intergrate the ttl circuits of all the circuits make the routing of the whole board very smooth . based on the above , the auto - routing design and the imitating - test improve the quality of routing and decrease the errors of hand - routing by protel1 99 , which makes a good design
  系统设计中还借助max + plusii和protel99两个强大的eda设计工具，采用max + plusii对整个电路中的ttl电路进行了集成化设计，使整个电路板的布线显得流畅，在此基础上采用protel99进行的自动布线设计以及仿真测试提高了布线的质量，减少了手动布线造成的错误,使得整个设计圆满完成。
