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.

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.

• Schottky Process for High Speed

• Multifunction Capability
