The 555 timer datasheet specifies that 555 IC is a highly stable device for generating accurate time delays or oscillation. Additional terminals are provided for triggering or resetting if desired.

TI’s LMC555 claims to be the smallest and fastest fully-featured 555 available. This is a CMOS variant, with a maximum frequency of 3 MHz according to the datasheet.

When it comes to the venerable 555 timer, Paul Rako agrees with Bob Pease—avoid using it if your application demands any kind of precision.

[R-B] designed a 555 timer circuit to scan a keypad. Keypads are common interfaces for small projects and require row and column scanning by a microcontroller. [R-B’s] setup allows you to red… ...

The bipolar NE555 timer IC is widely used in inductorless dc-dc converters, most frequently in doubling and inverting converters. However, another very popular IC, the LM386 audio amplifier, may ...

Used in a variety of timer, pulse generation, and oscillator applications, the 555 was designed in 1971 by Hans Camenzind. A favorite for many engineers, ...
