Part # 74LS155 datasheet

Part Manufacturer: Motorola


Part Description: 74LS155

Part Details:

SN54/74LS155 DUAL 1-OF-4 DECODER/ SN54/74LS156 DEMULTIPLEXER The SN54 / 74LS155 and SN54 / 74LS156 are high speed Dual 1-of-4 Decoder/Demultiplexers. These devices have two decoders with common2-bit Address inputs and separate gated Enable inputs. Decoder "a" has an DUAL 1-OF-4 DECODER / Enable gate with one active HIGH and one active LOW input. Decoder "b" has DEMULTIPLEXER two active LOW Enable inputs. If the Enable functions are satisfied, oneoutput of each decoder will be LOW as selected by the address inputs. The LS156-OPEN-COLLECTOR LS156 has open collector outputs for wired-OR (DOT-AND) decoding and LOW POWER SCHOTTKY 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 TTLfamilies.· Schottky Process for High Speed J SUFFIX · Multifunction Capability CERAMIC · Common Address Inputs CASE 620-09 · True or Complement Data Demultiplexing 16 1 · Input Clamp Diodes Limit High Speed Termination Effects · ESD > 3500 Volts N SUFFIX PLASTIC CASE 648-08 16 CONNECTION DIAGRAM DIP (TOP VIEW) 1 VCC Eb Eb A0 O3b O O 2b 1b O0b 16 15 14 13 12 11 10 9 NOTE: D SUFFIX The Flatpak version SOIC 16
