74LS155-SN74LS155N-SN74LS156N
Dual 2-Line to 4-Line Decoders/Demultiplexers
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.
The LS155 and LS156 are fabricated with the Schottky barrier diode
process for high speed and are completely compatible with all Motorola TTL
families. Schottky Process for High Speed Multifunction Capability Common Address Inputs True or Complement Data Demultiplexing Input Clamp Diodes Limit High Speed Termination Effects ESD > 3500 Volts

NOTES: 1 TTL Unit Load (U.L.) = 40 μA HIGH/1.6 mA LOW. 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.
