Separate Latch Enable (LEAB or LEBA), and Output Enable (OEAB and OEBA) inputs are provided for each register to permit independent control in either direction of data flow. The A-to-B Enable (CEAB) input must be LOW to enter data from A or to output data from B. If CEAB is LOW and LEAB is LOW, the A-to-B latches are transparent; a subsequent low-to-high transition of LEAB puts the A latches in the storage mode. With CEAB and OEAB both LOW, the 3-State B outputs are active and reflect the data present at the output of the A latches. Data flow from B to A is similar but requires using CEBA, LEBA, and OEBA. To ensure the high-impedance state during power up or power down, OE should be tied to VCC through a pull-up resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver. Active bus-hold circuitry is provided to hold unused or floating data inputs at a valid logic level.
