74ALVC16835A
18-bit registered driver; 3-state
Rev. 7 — 19 January 2018
Product data sheet
1 General description
The 74ALVC16835A is a 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 pullup resistor; the minimum value of the resistor is determined by the
current-sinking capability of the driver.
