-//- Identifier: NE555_DIP
-//- Title: NE555 PRECISION TIMERS
-//- Description:
-//- These devices are precision timing circuits capable of producing accurate
-//- time delays or oscillation. In the time-delay or monostable mode of
-//- operation, the timed interval is controlled by a single external resistor
-//- and capacitor network. In the astable mode of operation, the frequency and
-//- duty cycle can be controlled independently with two external resistors and
-//- a single external capacitor.
-//-
-//- The threshold and trigger levels normally are two-thirds and one-third,
-//- respectively, of V CC. These levels can be altered by use of the
-//- control-voltage terminal. When the trigger input falls below the trigger
-//- level, the flip-flop is set and NC – No internal connection the output
-//- goes high. If the trigger input is above the trigger level and the
-//- threshold input is above the threshold level, the flip-flop is reset and
-//- the output is low. The reset (RESET) input can override all other
-//- inputs and can be used to initiate a new timing cycle. When RESET goes
-//- low, the flip-flop is reset and the output goes low. When the output is low,
-//- a low-impedance path is provided between discharge (DISCH) and ground.
-//-
-//- The output circuit is capable of sinking or sourcing current up to 200 mA.
-//- Operation is specified for supplies of 5 V to 15 V. With a 5-V supply,
-//- output levels are compatible with TTL inputs.
-//-
-//- The NE555 is characterized for operation from 0°C to 70°C. The SA555 is
-//- characterized for operation from –40°C to 85°C. The SE555 is characterized
-//- for operation over the full military range of –55°C to 125°C.
-//-
-//- Pinalias: GND,TRIG,OUT,RESET,CONT,THRES,DISCH,VCC
-//- Package: DIP
-//- NamingConvention: Naming conventions follow Texas instrument datasheet
-//- Limitations: Internal resistor network currently fixed to 5k
-//- If TRIG and TRESH are connected overshoot compensation will be enabled.
-//- The approach is raw but delivers results (at 5 to 10 steps per discharge/charge)
-//- within a couple of percent. Please take into account that any datasheet
-//- formulas are idealistic. Neither capacitor, resistor, internal resistor
-//- tolerances are taken into account. Nor are ambient temperature and chip
-//- temperature. Thus the result is considered acceptable.
-//- The datasheet states a maximum discharge of 200mA, this is not modelled
-//- Instead an impedance of 1 Ohm is used.
-//-
-//- Example: ne555_astable.c,ne555_example

-//- |Low | Irrelevant | Irrelevant | Low | On |
-//- |High | <1/3 VDD | Irrelevant | High | Off |
