Pcb Etching Acid Solution (250 mm) 4 Channels Humidity Range: 0% to 100%

Humidity Range: 0% to 100%

all the segment outputs are HIGH independent of all other input conditions

It also acts as a wetting agent

When there is light

74HC138 can be used as an eight output demultiplexer by using one of the activeLOW enable inputs as the data input and the remaining enable inputs as strobes
