DESCRIPTION/ORDERING INFORMATION  
A2  
GND  
NC  
This 1-bit to 4-bit address register/driver is designed  
for 1.65-V to 3.6-V VCC operation. The device is ideal  
for use in applications in which a single address bus  
is driving four separate memory locations. The  
SN74ALVCH16831 can be used as a buffer or a  
register, depending on the logic level of the select  
(SEL) input.

When SEL is logic high, the device is in the buffer  
mode. The outputs follow the inputs and are  
controlled by the two output-enable (OE) controls.  
Each OE controls two groups of nine outputs.  
When SEL is logic low, the device is in the register  
mode. The register is an edge-triggered D-type  
flip-flop. On the positive transition of the clock (CLK)  
input, data set up at the A inputs is stored in the  
internal registers. OE controls operate the same as in  
buffer mode.

When OE is logic low, the outputs are in a normal  
logic state (high or low logic level). When OE is logic  
high, the outputs are in the high-impedance state.  
NC

SEL and OE do not affect the internal operation of  
the flip-flops. Old data can be retained or new data  
can be entered while the outputs are in the  
high-impedance state.

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 holds unused or undriven  
inputs at a valid logic state. Use of pullup or pulldown  
resistors with the bus-hold circuitry is not  
recommended.
