TC74HC139AP, TC74HC139AF
Dual 2-to-4 Line Decoder
The TC74HC139A is a high speed
CMOS 2-to-4 LINE DECODER/DEMULTIPLEXER fabricated with silicon gate C2MOS technology.
It achieves the high speed operation similar to equivalent LSTTL while maintaining the
CMOS low power dissipation.
The active low enable input can be used for gating or it can be used as a data input for demultiplexing applications.
When the enable input is held “H”, all four outputs are fixed at a high logic level independent of the other inputs.
All inputs are equipped with protection circuits against static discharge or transient excess
voltage.
