USA555 timers equivalent, precision timers.
* Astable or monostable operation * Low turn off time * Operates in both astable and monostable modes * Timing from microseconds to hours * Adjustable duty cycle * TTL-c.
2. T1 = 0.693 × (RA+RB)×C1 T2 = 0.693 × RB × C1
f=
1 T
1.44 = (RA + 2RB) × C1
3. Formula 0.693 values for referenc.
The UTC USA555 monolithic timing circuit is a highly stable controller capable of producing accurate time delays or oscillation. In the time-delay or monostable mode of operation, the timed interval is controlled by a single external resistor and ca.
