74HC139D circuits equivalent, cmos digital integrated circuits.
(1) High speed: tpd = 10 ns (typ.) at VCC = 5 V (2) Low power dissipation: ICC = 4.0 µA (max) at Ta = 25 (3) Balanced propagation delays: tPLH ≈ tPHL (4) Wide operating.
When the enable input is held "H", all four outputs are fixed at a high logic level independent of the other inputs. Al.
