DESCRIPTION  
This 16-bit registered transceiver is designed for  
1.65-V to 3.6-V VCC operation.  
The SN74ALVCH16543 can be used as two 8-bit  
transceivers or one 16-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 CEBA,  
LEBA, and OEBA.  
To ensure the high-impedance state during power up or power down, 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.  
The SN74ALVCH16543 is characterized for operation from -40°C to 85°C.
