TC74VHCT139AFN decoder equivalent, dual 2-to-4 line decoder.
* High speed: tpd = 5.0 ns (typ.) at VCC = 5 V
* Low power dissipation: ICC = 4 µA (max) at Ta = 25°C
* Compatible with TTL outputs: VIL = 0.8 V (max)
VIH = 2.
When the enable input is held High, all four outputs are fixed at a high logic level independent of the other inputs.
