50% duty cycle 555 circuit

HQS-VX3XL-05000-50-50
Probe domestic double-head probe 038-BB-5.7L The shape of the two ends of the needle is outside the pointed needle
50% duty cycle 555 circuit
50% duty cycle and frequency control using external charging transistors and diodes. When the 555 discharge transistor is turned off, the 2N2222 acts as a transmit follower. When the discharge transistor is turned on, 2N2222 is turned off, and C1 is discharged through (R1+R2) at the same rate. The IN4l48 provides temperature compensation.
