SN74LS156

SN74LS156 Dual 1-of-4 Decoder/ Demultiplexer The SN74LS156 is a high speed Dual 1-of-4 Decoder/ Demultiplexer. This device has two decoders with common 2-bit Address inputs and separate gated Enable inputs. Decoder “a” has an Enable gate with one active HIGH and one active LOW input. Decoder “b” has two active LOW Enable inputs. If the Enable functions are satisfied, one output of each decoder will be LOW as selected by the address inputs. The LS156 has open collector outputs for wired-OR (DOT-AND) decoding and function generator applications. The LS156 is fabricated with the Schottky barrier diode process for high speed and are completely compatible with all ON Semiconductor TTL families.
