Hi,

I would like to ask you a question about timer device.

LM555 SOIC-8 0～70 ℃ Tj:150℃

NA555 SOIC-8　-40～105℃　Tj:150℃

NE555 SOIC-8　0～70 ℃ Tj:150℃

SA555　SOIC-8　-40～85 ℃ Tj:150℃

SE555　SOIC-8　-55～125℃　Tj:150℃

The difference is just temperature?

Thank you in advance.

Takumi-san,

All are the same except for small differences.

LM555 was design by National Semiconductor.

SE555 has slightly different data sheet specifications.
