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 V
CC
through a pullup resistor; the
minimum value of the resistor is determined by the current-sinking
capability of the driver.

Short-form specification -- The data in a short-form specification is extracted from a full data sheet with the same type number and title. For
detailed information see the relevant data sheet or data handbook.
Limiting values definition -- Limiting values given are in accordance with the Absolute Maximum Rating System (IEC 134). Stress above one
or more of the limiting values may cause permanent damage to the device. These are stress ratings only and operation of the device at these or
at any other conditions above those given in the Characteristics sections of the specification is not implied. Exposure to limiting values for extended
periods may affect device reliability.
