SN54/74LS156  
DUAL 1-OF-4 DECODER/  
DEMULTIPLEXER  
The SN54/74LS155 and SN54/74LS156 are high speed Dual 1-of-4  
Decoder/Demultiplexers. These devices have 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.

DEMULTIPLEXER  
LS156-OPEN-COLLECTOR  
LOW POWER SCHOTTKY  
The LS155 and LS156 are fabricated with the Schottky barrier diode  
process for high speed and are completely compatible with all Motorola TTL  
families.
