MC54HC139A General Description
The MC54/74HC139A is identical in pinout to the LS139. The device inputs are compatible with standard CMOS outputs; with pullup resistors, they are compatible with LSTTL outputs.
This device consists of two independent 1of4 decoders, each of which decodes a twobit Address to oneoffour activelow outputs. Activelow Selects are provided to facilitate the demultiplexing and cascading functions. The demultiplexing function is accomplished by using the Address inputs to select the desired device output, and utilizing the Select as a data input.

For high frequency or heavy load considerations, see Chapter 2 of the Motorola HighSpeed CMOS Data Book (DL129/D).
This device contains protection circuitry to guard against damage due to high static voltages or electric fields.However, precautions must be taken to avoid applications of any voltage higher than maximum rated voltages to this highimpedance circuit. For proper operation, Vin and Vout should be constrained to the range GND (Vin or Vout) VCC.
Unused inputs must always be tied to an appropriate logic voltage level (e.g., either GND or VCC). Unused outputs must be left open.
