KA555 - Single Timer

Description

The KA555 is a highly stable controller capable of producing accurate timing pulses.

With a monostable operation, the time delay is controlled by one external resistor and one capacitor.

Features

  • High Current Drive Capability (200mA).
  • Adjustable Duty Cycle.
  • Temperature Stability of 0.005%/°C.
  • Timing From µsec to Hours.
  • Turn Off Time Less Than 2µsec.
