FK PACKAGE (TOP VIEW) D9 D8 VCC D7 D6 D5 D4 The 3-state control gate is a 2-input AND gate with active-low inputs so that if either output-enable (OE1 or OE2) input is high, all 12 outputs are in the high-impedance state. These devices provide inverted data. The outputs, which are designed to source or sink up to 12 mA, include equivalent 25-Ω series resistors to reduce overshoot and undershoot. To ensure the high-impedance state during power up or power down, OE should be tied to VCC through a pullup resistor; the.
