74155 DeMultiplexer IC

SN74155 Dual 2-Line To 4-Line Decoders, Demultiplexers

These monolithic transistor-transistor-logic (TTL) circuits feature dual 1-line-to-4-line demultiplexers with individual strobes and common binary-address inputs in a single 16-pin package. When both sections are enabled by the strobes, the common binary-address inputs sequentially select and route associated input data to the appropriate output of each section.

The individual strobes permit activating or inhibiting each of the 4-bit sections as desired. Data applied to input 1C is inverted at its outputs and data applied at 2C is not inverted through its outputs. The inverter following the 1C data input permits use as a 3-to-8-line decoder or 1-to-8-line demultiplexer without external gating. Input clamping diodes are provided on all of these circuits to minimize transmission-line effects and simplify system design.

We have Various sizes of 7400 Series IC. Check out our complete collection of 7400 Series IC.


If you are in Nashik you can buy this Electronic Component at our local shop at New CBS, Nashik or you can place order online and get it delivered at your doorstep anywhere in India.
