NE/SE/SA58/559-F,N DESCRIPTION PIN CONFIGURATION The SA/SE/NE558 and 559 Quad Timers are monolithic timing devices which can be F,N PACKAGE used to produce four entirely independent timing functions. The 558 output sinks cur- rent whereas the 559 sources current. These + i OUTPUT D highly stable, general purpose controllers OUTPUT A oe can be used in a monostable mode to pro- duce accurate time delays, from microse- Timinc a 2] TIMING D conds to hours. In the time delay mode of operation, the time is precisely controlled by one external resistor and one capacitcr.

After reset the trigger must be brought high and then low to implement triggering. 2. For reset below 0.8 volts, outputs set low and trigger inhibited. For reset above 2.4 volts, trigger enabled. 3. The 558 output structure is open collector which requires a pult up resistor to Vcc to sink current. The output is normally low sinking current 4. The 559 output structure is a darlington emitter follower which requires a pull down resistor to ground to source current. The output is normaliy low and sources current only when switched high.
