Please be aware that an important notice concerningavailability, standard warranty, and use in critical applications ofTexasInstruments semiconductor products and disclaimers theretoappears at the end of this data sheet.
One of the main applications of the SN74ALS156 is as a dual 1-lineto 4-line decoder/demultiplexer with individual strobes (G\) andcommon binary-address inputs in a single 16-pin package. When bothsections are enabled, the common binary-address inputs sequentiallyselect and route associated input data to the appropriate output ofeach section. The individual strobes permit enabling or disablingeach of the 4-bit sections, as desired.
Data applied to input 1C is inverted at its outputs and dataapplied at input 2C\ is not inverted through its outputs. Theinverter following the 1C data input permits use of the SN74ALS156 asa 3-line to 8-line demultiplexer without external gating. All inputsare clamped with high-performance Schottky diodes to suppress lineringing and simplify system design.
The SN74ALS156 is characterized for operation from 0°C to70°C.
