1. General description

The 74ALVC16836A is a 20-bit universal bus 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/flipflop.

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 pullup resistor; the minimum value of the resistor is determined by the current-sinking

capability of the driver.
