CA555, CA555C, LM555C
Timers for Timing Delays and Oscillator
Applications in Commercial, Industrial
and Military Equipment
The CA555 and CA555C are highly stable timers for use in
precision timing and oscillator applications. As timers, these
monolithic integrated circuits are capable of producing
accurate time delays for periods ranging from microseconds
through hours. These devices are also useful for astable
oscillator operation and can maintain an accurately
controlled free running frequency and duty cycle with only
two external resistors and one capacitor.
The circuits of the CA555 and CA555C may be triggered by
the falling edge of the waveform signal, and the output of
these circuits can source or sink up to a 200mA current or
drive TTL circuits.
These types are direct replacements for industry types in
packages with similar terminal arrangements e.g. SE555
and NE555, MC1555 and MC1455, respectively. The CA555
type circuits are intended for applications requiring premium
electrical performance. The CA555C type circuits are
intended for applications requiring less stringent electrical
characteristics.
