Part # 74LS139 datasheet

Part Manufacturer: Motorola


Part Description: 74LS139

Part Details:

SN54/74LS139 DUAL 1-OF-4 DECODER/DEMULTIPLEXER The LSTTL/MSI SN54/74LS139 is a high speed Dual 1-of-4 Decoder /De- multiplexer. The device has two independent decoders, each accepting twoinputs and providing four mutually exclusive active LOW Outputs. Eachdecoder has an active LOW Enable input which can be used as a data input DUAL 1-OF-4 DECODER / for a 4-output demultiplexer. Each half of the LS139 can be used as a function DEMULTIPLEXER generator providing all four minterms of two variables. The LS139 isfabricated with the Schottky barrier diode process for high speed and is LOW POWER SCHOTTKY completely compatible with all Motorola TTL families.· Schottky Process for High Speed · Multifunction Capability · Two Completely Independent 1-of-4 Decoders · Active Low Mutually Exclusive Outputs J SUFFIX · Input Clamp Diodes Limit High Speed Termination Effects CERAMIC · ESD > 3500 Volts CASE 620-09 16 1 CONNECTION DIAGRAM DIP (TOP VIEW) VCC Eb AOb A1b O0b O O 1b 2b O3b 16 15 14 13 12 11 10 9 N SUFFIX PLASTIC NOTE: CASE 648-08 The Flatpak version 16 has the same pinouts 1 (Connection Diagram) asthe Dual In-Line Package. 1 2 3 4 5 6 7
