The permanently connected LED is used to indicate the TTL voltage level and the changes of this level. If the LED-1 turns on, it means the input voltage is TTL high-level voltage, If the LED-1 turns off, it means the input voltage is TTL low-level voltage. When the input voltage level changes, LED-2 lights one time. This circuit can check the voltage level, the level jump, the single pulse and the cluster pulse. Only half of each IC has used, so you need, you can use the same number of ICs as the two test probes. The in-phase driver of the monostable IC9602 is composed of the la and lc. This monostable in-phase driver IC9602 is triggered by the positive edge and negative edge of C1 and D1. If the cluster pulse's period is less than the width of the flash pulse, the edge LED-2 will always light.
