Packages

This 16-bit universal bus driver is designed for 1.65-V

to 3.6-V V

operation.

Data flow from A to Y is controlled by the

output-enable ( OE) input. The device operates in the

transparent mode when the latch-enable ( LE) input is

low. When LE is high, the A data is latched if the

clock (CLK) input is held at a high or low logic level. If

LE is high, the A data is stored in the latch/flip-flop on

the low-to-high transition of CLK. When OE is high,

the outputs are in the high-impedance state.

<br/>

To ensure the high-impedance state during power up or power down, OE should be tied to V

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 SN74ALVCH16334 is characterized for operation from -40 ° C to 85 ° C.
