Product data sheet

1 General description

The 74ALVC16834A is an 18-bit registered driver. Data flow is controlled by active low

output enable (OE), active low latch enable (LE) and clock inputs (CP).

When LE is LOW, the A to Y data flow is transparent. When LE is HIGH and CP is held

at LOW or HIGH, the data is latched; on the LOW to HIGH transient of CP the A-data is

stored in the latch/flip-flop.

When OE is LOW the outputs are active. When OE is HIGH, the outputs go to the high

impedance OFF-state. Operation of the OE input does not affect the state of the latch/

flip-flop.

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

to VCC through a pull-up resistor; the minimum value of the resistor is determined by the

current-sinking capability of the driver.
