The SN74ALVCHR16409 allows synchronous data  
exchange between four different buses. Data flow is  
controlled by the select (SEL0-SEL4) inputs. A  
data-flow state is stored on the rising edge of the  
clock (CLK) input if the select-enable (SELEN) input  
is low. Once a data-flow state has been established,  
data is stored in the flip-flop on the rising edge of  
CLK if SELEN is high.  
The data-flow control logic is designed to allow glitch-free data transmission.  
The B outputs, which are designed to sink up to 12 mA, include equivalent 26-Ω series resistors to reduce  
overshoot and undershoot.  
When preset (PRE) transitions high, the outputs are disabled immediately, without waiting for a clock pulse. To  
leave the high-impedance state, both PRE and SELEN must be low, and a clock pulse must be applied.  
To ensure the high-impedance state during power up or power down, PRE 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 SN74ALVCHR16409 is characterized for operation from -40°C to 85°C.
