555 Bistable 01 555 Multivibrator 555 Retriggerable Monostable 555 Monostable w/ Relay 555 Bistable 04

This circuit is has a Set input, controlled by Q1.  If input a high it will take the output high.  Pin 4 is a inverted reset input, if taken low it will go low. RC Oscillator Monostable configurations with relay

Example 1 shows a button triggered monostable.

Example 2 shows a power on triggered monostable. 555 Hi Voltage Osc 555 Multivibrator w/ diode 7555 Monostable, meant to drive a lightweight motor from a low voltage source. Dice Oscillator

This circuit will oscillate at max speed using standard 555 calculation before slowing down and stopping.  This will create a dramatic effect for game circuits such as dice or heads / tails. 555/556 Design Data and Schematics

Includes the math and schematics needed to design with these chips.  Lifted out of the data book for the most part. 555 Fader 03 555/556 Design Data and Schematics Page 2
