the sss timer i$ one of the most popular produced. it includes 23 transistors, 2 00066 and 16 resistors on А. silicon chip installed in an 8-pin mini dval-in-line package (dip). the 556 is А 14-pin oip ТААТ combines two sss's on Å single chip. also available are ultra-low power versions of the sss.
The IC 555 is the most versatile linear integrated circuit introduced by signetics corporation. Fig. 1 shows the pin diagram and block diagram of NE 555 Timer.
These chips, properly assembled, display characteristics similar to the NE555 (see electrical table for NE555Y). Thermal compression or ultrasonic bonding may be used on the doped aluminum bonding pads.
