Texas Instruments SN74ALS156

the SN74ALS156 is as a dual 1-line to 4-line decoder /demultiplexer with individual strobes (G) and common binary-address inputs in a single 16-pin package. When both sections are enabled, the common binary-address inputs sequentially select and route associated input data to the appropriate output of each section. The individual strobes permit enabling or disabling each of the 4-bit sections, as desired.

The inverter following the 1C data input permits use of the SN74ALS156 as a 3-line to 8-line demultiplexer without external gating. All inputs are clamped with high-performance Schottky diodes to suppress line ringing and simplify system design. The SN74ALS156 is characterized for operation from 0°C to 70°C.
