Hot-selling and scarce MM74HC139N Dual 2-To-4 Line Decoder DIP16 spot stock

Product Descriptions

The MM74HC139 decoder utilizes advanced silicon-gate CMOS technology, and is well suited to memory address decoding  or  data  routing  applications.  It  possesses  the high noise immunity and low power consumption usually associated with CMOS circuitry, yet has speeds comparable to low power Schottky TTL logic.

The  MM74HC139  contain  two  independent  one-of-four decoders each with a single active low enable input (G1, orG2). Data on the select inputs (A1, and B1 or A2, and B2) cause one of the four normally high outputs to go LOW. 

The decoder’s outputs can drive  10 low power Schottky TTL equivalent loads, and are functionally as well as pin equivalent to the 74LS139 . All inputs are protected from damage  due  to  static  discharge  by  diodes  to V CC  and ground.​
