Timers for Timing Delays and Oscillator

Applications in Commercial, Industrial

and Military Equipment

Features

• Accurate Timing From Microseconds Through Hours

• Astable and Monostable Operation

[ /Title

(CA55

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

• Adjustable Duty Cycle

• Output Capable of Sourcing or Sinking up to 200mA

• Output Capable of Driving TTL Devices

• Normally ON and OFF Outputs

CA555 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.

• High Temperature Stability . . . . . . . . . . . . . . . . 0.005%/ C

• Directly Interchangeable with SE555, NE555, MC1555,

and MC1455

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.

Applications

• Precision Timing

Timing

These types are direct replacements for industry types in

Delays

• Sequential Timing

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.
