LTspice does not show any subversion numbers as many software programs do, though the software "build date" could be treated as such.

The 555 timer IC is an integral part of electronics projects. Be it a simple project involving a single 8-bit micro-controller and some peripherals or a complex one involving system on chips (SoCs), 555 timer working is involved. These provide time delays, as an oscillator and as a flip-flop element ... The 555 comes as a single timer in an 8-pin package or a dual timer (556) in a 14 pin package. The 7555 comes as a single timer in an 8-pin package or a dual timer (7556) in a 14 pin package. The 555 and 7555 are called TIMERS or Timer Chips. They contain about 28 transistors and the only extra components you need are called TIMING COMPONENTS.

While PLC vendors do not need to use the terms of

Three Fives Kit Datasheet (Rev 2.01, August 2014) 1 The “Three Fives” Discrete 555 Timer kit is a faithful and functional transistor-scale replica of the classic NE555 timer integrated circuit. Designed by Eric Schlaepfer (tubetime.us), in collaboration with Evil Mad Scientist Laboratories. Main Specifications An Overview of the 555 Timer The 555 Integrated Circuit (IC) is an easy to use timer that has many applications. It is widely used in electronic circuits and this popularity means it is also very cheap to purchase, typically costing around 30p. How To Configure a 555 Timer IC 555 Timer Tutorial By Philip Kane The 555 timer was introduced over 40 years ago. Due to its relative simplicity, ease of use and low cost it has been used in literally thousands of applications and is still widely available. Here we describe how to configure Time measured from a positive pulse (from 0 V to 0.8 x VCC) on the threshold pin to the transition from high to low on the output pin. Trigger is tied to threshold. Table 3. Tamb = +25° C, VCC = +5 V to +15 V (unless otherwise specified) (continued) Symbol Parameter SE555 NE555 - SA555 Unit Min. Dual timer that switches on and off repeatedly and variably Timer is programmed using a rotary switch and is easy to install in standardised sections (48x48 mm)Output signal emitted after two time periods Functions: -cyclical (OFF-start, various definable on- and off-times)Protection rating IP65 with ATC 18002 seal.
