This logic probe features either high-low (LED) indication or latching operation. When S1 closed, the indication of a pulse is latched and the red LED1 stays on. Piezoelectric buzzer BZ1 used as a beeper to sound that a logic high is preset.
This device contains four independent gates, each of which performs the logic NOR function.
