Enhanced-product three-line to eight-line decoders/demultiplexers

The SN74LV8T138-EP is a

three to eight decoder with one standard output strobe (G2) and two

active low output strobes (G1 and

G0). When the outputs are gated by any of the

strobe inputs, they are all forced into the high state. When the outputs are not

disabled by the strobe inputs, only the selected output is low while all others are

high. The output level is referenced to the supply voltage (VCC) and

supports 1.8V, 2.5V, 3.3V, and 5V CMOS levels.

The input is designed with a lower threshold

circuit to support up translation for lower voltage CMOS inputs (for example, 1.2V

input to 1.8V output or 1.8V input to 3.3V output). In addition, the 5V tolerant

input pins enable down translation (for example, 3.3V to 2.5V output).
