It's a prefix of the IC products of 'Linear Monolithic' category of National semiconductors.
LM stands for "Linear Monolithic"
LM stand for Liner Monolithic ic that is the National Instrunt perfix, I My right
The 555 is a timer, not a counter.
linear monolithic
The "LM" stands for Linear Monolithic" and is just part of the part-number that National decided to use for this famous timer IC. The LM prefix is still used for a lot of medium complexity analog chips, like regulators and op-amps.
555 is an arbitrarily assigned part number for a general purpose programmable timer IC. The number itself has no special meaning.
The 555 IC timer does not have a clock.

Full form of LM in any IC like LM317 is linear monolithic
556 is a dual version of 555 single timer.
The 555 is a timer, not a counter.
LM is a manufacturer's code--all LM chips were made by National Semiconductor. Similarly, SN chips were made by Texas Instruments.
555 timer is used to generate clock signals in the ic 555 timer the pin no 8 is represents vcc
just conect gnd to the vcc
A: An lm317 is a negative 1.25v regulator
