UTCNE558 LINEAR INTEGRATED CIRCUIT
QUAD TIMER
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.
FEATURES
*Wide supply voltage: Vcc= 4.5V~15V
*100mA output current per-section
*Edge trigger without coupling capacitor
*Time period equals RC
*Output independent
APPLICATIONS
*Precision timing
*Quad one-shot
*Timing delay generation
*Sequential timing.

Note 1: The trigger functions only on the falling edge of the trigger pulse only after previously being high. After
reset, the trigger must be brought high and then low to implement triggering.
Note 2: For reset below 0.8V, output s set low and trigger inhibited.
Note 3: Output structure is open collector which requires a pull up resistor to Vcc to sink current. The output is
normally low sinking current.
