3 Description

The SN74LV8T139-EP contains two two-to-four

decoders with one active low output strobe G. When

the outputs of one channel are gated by the strobe

input, they are all forced into the high state. When the

outputs are not disabled by the strobe input, only the

selected output is low while all others are high.
