Texas Instruments SN74LV138A/SN74LV138A-Q1 Decoders/Demultiplexers

Texas Instruments SN74LV138A/SN74LV138A-Q1 3-to-8 Line Decoders / Demultiplexers are 3-line to 8-line decoders/demultiplexers designed for 2V to 5.5V V_CC 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 are used to reduce the need for external gates or inverters when expanding. The Texas Instruments SN74LV138A-Q1 devices are AEC-Q100 qualified for automotive applications.

Features
