SE555Q - AUTOMOTIVE GRADE PRECISION TIMERS

General Description

SE555Q is precision timing circuit 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 capacitor network.

roducing 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 capacitor network. In the astable mode of operation, the frequency and duty cycle can be controlled independently with two external resistors and a single external capacitor. The threshold and trigger levels normally are two-thirds and one-third, respectively, of VCC. These levels can be altered by use of the control-voltage terminal. When the trigger input falls below the trigger level, the flip-flop is set, and the output goes high.
