具有三态输出的36位寄存总线收发器 36-BIT REGISTERED BUS TRANSCEIVERS WITH 3-STATE OUTPUTS
The "ABTH32543 are 36-bit registered transceivers that contain two sets of D-type latches for temporary storage of data flowing in either direction. These devices can be used as two 18-bit transceivers or one 36-bit transceiver. 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.
When VCC is between 0 and 2.1 V, the device is in the high-impedance state during power up or power down. However, to ensure the high-impedance state above 2.1 V, OE\ should be tied to VCC through a pullup 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.
