LS156-OPEN-COLLECTOR LOW POWER SCHOTTKY

TheSN54/74LS155 and SN54/74LS156 are high speed Dual 1-of-4 Decoder/Demultiplexers.These deviceshave two decoders with common 2-bit Address inputs and separate gated Enable inputs. Decoder “a” has an Enablegate with one active HIGH andone active LOW input. Decoder “b” has twoactive LOW Enable inputs. If the Enable functions are satisfied,one output of each decoder will be LOW as selected by the address inputs. The LS156has open collector outputs for wired-OR (DOT-AND) decoding and function generator applications. TheLS155 and LS156 are fabricated with the Schottky barrier diode processfor high speed andare completely compatible with all Motorola TTL families.
