Philips NE558D, NE558F, NE558N Datasheet

Philips Semiconductors Linear Products	Product specification
Quad timer	NE558

DESCRIPTION

The 558 Quad Timers are monolithic timing devices which can be used to produce four independent timing functions. The 558 output sinks current. These highly stable, general purpose controllers can be used in a monostable mode to produce accurate time delays; from microseconds to hours. In the time delay mode of operation, the time is precisely controlled by one external resistor and one capacitor. A stable operation can be achieved by using two of the four timer sections.

The four timer sections in the 558 are edge-triggered; therefore, when connected in tandem for sequential timing applications, no coupling capacitors are required. Output current capability of 100mA is provided in both devices.

FEATURES

•100mA output current per section

•Edge-triggered (no coupling capacitor)

•Output independent of trigger conditions

•Wide supply voltage range 4.5V to 16V

•Timer intervals from microseconds to hours

•Time period equals RC

•Military qualifications pending

NOTES:

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.

2.For reset below 0.8V, outputs set low and trigger inhibited. For reset above 2.4V, trigger enabled.

3.The 558 output structure is open-collector which requires a pull-up resistor to VCC to sink current. The output is normally low sinking current.
