SN74LS155
DUAL 1-OF-4 DECODER/
DEMULTIPLEXER
The SN54 / 74LS156 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 Motorola TTL
families.

b) The Output LOW drive factor is 2.5 U.L. for Military (54) and 5 U.L. for Commercial (74)
Temperature Ranges. The HIGH level drive for the LS156 must be established by an
external resistor.
