The Model 575A is able to locate intermittent and temperature related faults by using its unconditional or conditional loop testing modes. Unknown device identification is easily accomplished by selecting SEARCH from the menu, selecting the number of pins on the device and activating Search Mode. The 575A will search its library and identify the device, displaying possible functional equivalents for replacement. As part of the IC test, the specific IC number, the functional description of the device, and the status of faulty pins are scrolled through on the built-in display.
Comprehensive device library covers most TTL, CMOS, memory and interface devices
40 pin capability (NAND gates or CPUs)
Identifies unmarked and house-coded devices
Detects intermittent and temperature related faults
Displays diagnostic information for individual pins
