Bipolar Schottky TTL while maintaining the CMOS low power dissipation. Features When the device is enabled, 3 Binary Select inputs (A , A 0 1 � High Speed: t = 7.6 ns (typ) at V = 5V PD CC and A ) determine which one of the outputs (O –O ) will go 2 0 7 � Low power dissipation: I = 4 μA (max.) at T = 25°C LOW. When enable input E is held LOW or either E or E CC A 3 1 2 is held HIGH, decoding function is inhibited and all outputs � Power down protection is provided on all inputs and go HIGH.
