[TCML] 555 timer

[huil888]

Nope -you bought a 555 timer in a tiny surface-mount package (SOIC or MSOP), 
not the DIP package you should have ordered.

You've got to read ALL the specs when you order IC's, especially as the DIP 
package has been semi-obsolescent for several years now, with much higher 
volumes of ICs being sold in surface-mount packages vs the 1970's vintage 
DIP package.
