Model 575A Digital IC Tester 1. introduction Thank you for purchasing the B & K Precision Model 575A Hand Held Digital IC Tester. The basic function of the B & K Model 575A Digital IC Tester is to test a digital IC for correct logical functioning as described in the truth table and/or function table. The B & K Model 575A applies the necessary signals to the inputs of the IC, monitoring the outputs at each stage and comparing them with the expected states.
Model 575A Digital IC Tester cover by removing the two cross head screws holding it in place. The batteries must be inserted in the correct orientation, as indicated by the drawing within the battery compartment. Incorrect insertion of batteries will not allow the unit to operate. Replace the battery cover and insert the screws. If the battery voltage falls too low, a low battery warning symbol will be displayed at the top left hand cell of the display in normal operating mode.
Model 575A Digital IC Tester 4. switching on To switch the unit on, simply press the 'ON' key. To preserve battery life, the unit powers itself off after approximately 3 minutes of nonuse or when “Sw Off” is selected from the main menu. When the unit is switched on, it first performs a self-diagnosis test. Therefore, before switching on, check that the test socket is empty to prevent interference with the diagnostics. If the unit passes the self-test, a pass result will be displayed on the screen.
Model 575A Digital IC Tester 5. operating modes The B & K Model 575A has a number of test modes that are selected using the MODE/CLEAR key from the initial screen. The test modes are as follows: Single Loop P Loop F Loop Search Diags CmLink Sw Off 6. - execute a single test on the IC in the socket. - execute test repeatedly, regardless of the result. - execute test repeatedly, provided the result was PASS. - execute test repeatedly, provided the result was FAIL.
Model 575A Digital IC Tester manual together with notes on any special requirements for certain ICs. Note that if you have stored a user library using CompactLink, an IC in the user library with the same number as one in the internal library will take precedence. This allows a new test to be written for an existing IC. If you wish both tests to be available, use a different number for your user test. 7.
Model 575A Digital IC Tester 8. test results A pre-determined sequence of signals is applied to the inputs of the IC and the IC outputs are monitored for the correct logic levels. The unit uses TTL or CMOS logic thresholds (depending on the selected IC) when evaluating the response of the IC outputs. If all the outputs respond correctly, the result PASS will be displayed at the top right of the display. A scrolling message will contain the IC function and power pin information.
Model 575A Digital IC Tester In the case of a FAIL result, the error conditions at all the nonfunctional pins of the IC will be scrolled on the display, and the IC function will be shown. The various failure conditions that can be displayed are as follows: LOW MID LOW HIGH MID HIGH LOAD 0V LOAD 5V - the - the - the - the output was LOW when HIGH was expected. output was LOW, but not a valid logic level. output was HIGH when LOW was expected. output was HIGH, but not a valid logic level.
Model 575A Digital IC Tester 10. continuous testing It is possible to test the same IC repeatedly to detect intermittent or temperature-related faults, or to rapidly test a batch of identical ICs. There are three types of test loop modes: Loop - execute a test repeatedly, regardless of the result. P Loop - execute a test repeatedly, provided the result is PASS. F Loop - execute a test repeatedly, provided the result was FAIL.
Model 575A Digital IC Tester Model 575A library, and it is a correctly functioning IC. This facility is useful when the IC type number is illegible or has been removed. Use the MODE/CLEAR key to choose SEARCH mode, insert the unknown IC into the socket and press the TEST/EXEC key. You will be prompted to choose the number of pins of the IC you wish to identify - use the MODE/CLEAR key to select from 8 to 40 pins or 'QUIT' to abandon this mode.
Model 575A Digital IC Tester should be noted and quoted in any correspondence relating to a unit fault. Contact your distributor in the event of a self-test fail, but first of all ensure that the socket was empty when the diagnostics were run. 13. CompactLink mode The B & K Model 575A is provided with an RS-232 interface to connect to a PC with a serial COM port or using a USB to RS-232 converter.

Model 575A Digital IC Tester 15.6. notes on TTL ICs Note 1: The 7450 and 7453 ICs have non-TTL compatible expander inputs that are often not used in designs. These inputs are not tested. Note 2: The 74LS51 and 74LS54 have differing pin connections and functions from the standard 7451 and 7454 ICs. The test assumes that the 'LS version is being tested - to test the standard version use the numbers 7450 and 7453 respectively.
Model 575A Digital IC Tester Note 6: The ROM/EPROM tests perform a blank check and checksum on the IC, and display the contents of the first 16 locations. These tests cannot confirm the integrity of an IC, or identify it in SEARCH mode, since they have no knowledge of the intended contents of the EPROM. Please be patient when testing EPROMs in this way - some of the larger ICs take a long time to read. 15.9.
