Description

The Electronic Component Model 74LS156B is an IC chip that belongs to the Dual 1-of-4 Decoder/Demultiplexer series, which is fabricated with the Schottky barrier diode process for high speed and is completely compatible with all Motorola TTL families. It 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, while Decoder “b” has two active LOW Enable inputs. The LS156 has open collector outputs for wired-OR (DOT-AND) decoding and function generator applications.
