description

These devices are precision monolithic timing
circuits 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

The threshold and trigger levels are normally two-thirds and one-third, respectively , of V
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. If the trigger input is above the trigger level and the threshold input is above
the threshold level, the flip-flop is reset and the output is low. RESET can override all other inputs and can be
used to initiate a new timing cycle. When RESET goes low, the flip-flop is reset and the output goes low.
Whenever the output is low, a low-impedance path is provided between DISCH and ground.

The output circuit is capable of sinking or sourcing current up to 200 mA. Operation is specified for supplies of
5 V to 15 V. With a 5-V supply, output levels are compatible with TTL inputs.

The NE555 is characterized for operation from 0°C to 70°C. The SA555 is characterized for operation from
–40°C to 85°C. The SE555 and SE555C are characterized for operation over the full military range of –55°C
to 125°C.
