The 74ALVCHT16835 is a 18-bit registered driver. Data flow is controlled by active low output enable (OE), active high latch enable (LE) and clock inputs (CP).
When LE is HIGH, the A to Y data flow is transparent. When LE is LOW 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.
WhenOE of the 74ALVCHT16835 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 of the 74ALVCHT16835 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
