74HC155 2 - 4 Line Decoder / Demultiplexer Integration with 4 outputs works with a supply voltage between 2- 6 V
the analog pin also TTL driven and works on 5V and hence can be used with most common microcontrollers
These pliers are ideal for cutting soft wire
The clock/calendar provides seconds
This enables the use of currentlimiting resistors to interface inputs to voltages in excess of VCC
