1. General description
The 74ALVC162334A is a 16-bit universal bus driver. Data flow is controlled by
active LOW output enable (OE), active LOW latch enable (LE), and clock input (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.
The 74ALVC162334A is designed with 30 W series resistors in both HIGH or LOW output
stages.
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.
