When both sections are enabled, the mon 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. Data applied to input 1C is inverted at its outputs and data applied at input 2C is not inverted through its outputs. 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.
