DESCRIPTION  
This 16-bit bus transceiver and register is designed  
for 1.65-V to 3.6-V VCC operation.  
The SN74ALVCH16646 can be used as two 8-bit  
transceivers or one 16-bit transceiver. Data on the A  
or B bus is clocked into the registers on the  
low-to-high transition of the appropriate clock (CLKAB  
or CLKBA) input. Figure  
fundamental bus-management functions that can be  
performed with the SN74ALVCH16646.

Output-enable (OE) and direction-control (DIR) inputs  
are provided to control the transceiver functions. In  
the transceiver mode, data present at the  
high-impedance port may be stored in either register  
or in both. The select-control (SAB and SBA) inputs  
can multiplex stored and real-time (transparent mode) data. The circuitry used for select control eliminates the  
typical decoding glitch that occurs in a multiplexer during the transition between stored and real-time data. DIR  
determines which bus receives data when OE is low. In the isolation mode (OE high), A data may be stored in  
one register and/or B data may be stored in the other register.  
When an output function is disabled, the input function is still enabled and may be used to store and transmit  
data. Only one of the two buses, A or B, can be driven at a time.  
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 SN74ALVCH16646 is characterized for operation from -40°C to 85°C.
