scbs704f ? august 1997 ? revised october 2003 2 post office box 655303 ? dallas, texas 75265 description/ordering information (continued) the ?lvth543 devices contain two sets of d-type latches for temporary storage of data flowing in either direction. separate latch-enable (leab or leba ) and output-enable (oeab or 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 the ceba , leba , and oeba inputs. active bus-hold circuitry holds unused or undriven inputs at a valid logic state. use of pullup or pulldown resistors with the bus-hold circuitry is not recommended. when v cc is between 0 and 1.5 v, the device is in the high-impedance state during power up or power down. however, to ensure the high-impedance state above 1.5 v, oe should be tied to v cc through a pullup resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver. this device is fully specified for hot-insertion applications using i off and power-up 3-state. the i off circuitry disables the outputs, preventing damaging current backflow through the device when it is powered down. the power-up 3-state circuitry places the outputs in the high-impedance state during power up and power down, which prevents driver conflict. function table ? inputs output ceab leab oeab a output b h x x x z x xhxz l hlxb 0 ? l llll l l l h h ? a-to-b data flow is shown; b-to-a flow control is the same, except that it uses ceba , leba , and oeba . ? output level before the indicated steady-state input conditions were established
