SN74LV138A Description
The SN74LV138A device is 3-line to 8-line decoders/ demultiplexers designed for 2 V to 5.5 V VCC operation. The conditions at the binary-select inputs (A0, A1, A2) and the three enable inputs (G2, G0, G1) select one of eight output lines. The two active-low (G0, G1) and one active-high (G2) enable inputs reduce the need for external gates or inverters when expanding.
