PRODUCTION DATA
Figure 7-3 is the simplified diagram of the CMTI testing. Common mode voltage is set to 1500V. The test is performed with IF = 6mA (VOUT= High) and IF = 0mA (VOUT = LOW). The diagram also shows the fail criteria for both cases. During the application on the CMTI pulse with IF = 6mA, if VOUT drops from VCC to ½VCC it is considered as a failure. With IF= 0mA, if VOUT rises above 1V, it is considered as a failure.
