NE558 - QUAD TIMER

General Description

The UTC NE558 is a monolithic quad timer which can be used to produce four entirely independent timing functions.

The highly stable, general purpose controller can be used in a monostable mode to produce accurate time delays.

Key Features

  • Wide supply voltage: Vcc= 4.5V~15V.
  • 100mA output current per-section.
  • Edge trigger without coupling capacitor.
  • Time period equals RC.
  • Output independent.
