| UTC NE558 QUAD TIMER DESCRIPTION LINEAR INTEGRATED CIRCUIT 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. SOP-16 FEATURES *Wide supply voltage: Vcc= 4.5V~15V *100mA output current per-section *Edge trigger without coupling capacitor *Time period equals RC *Output independent DIP-16 APPLICATIONS *Precision timing *Quad one-shot *Timing delay generation *Sequential timing.

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. UTC UNISONIC TECHNOLOGIES CO., LTD. 2 QW-R106-003,A |
