摘要
在测试74LS系列IC的过程中,为解决插拔被测IC时测试插座带电的问题,设计了一种由两片单片机组成、上位机为下位机程控供电的新型数字IC测试仪,该测试仪实现了插拔被测IC时测试插座完全断电,并具有时钟和温度显示等辅助功能。
In order to solve the problem of the plug measured IC test sockets charged , in the process of testing 74LS series IC, a new kind of digital IC tester has been designed. It consists of two MCU, and host - computer controls the power supply of lower system. The test instrument plug measured IC test socket is completely powered off, and the tester has the auxiliary function that includes clock and temperature display etc.
