74ALVC162834ADGG中文资料18-bit registered driver with inverted register enable and 30 Ohm termination resistors; 3-state数据手册Nexperia规格书

描述 Description

The 74ALVC162834A 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.
The 74ALVC162834A is designed with 30 Ω 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 pullup resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.
