1. Stresses beyond those listed under "absolute maximum ratings" may cause permanent damage to the device. These are stress ratings
only, and functional operation of the device at these or any other conditions beyond those indicated under "recommended operating
conditions" is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
2. The input negative-voltage and output voltage ratings may be exceeded if the input and output current ratings are observed.
3. This value is limited to 4.6 V maximum.
4. The package thermal impedance is calculated in accordance with JESD 51.


Description

The 74ALVCHS162830 address driver is designed for 2.3 V to 3.6 V VCC operation.

Diodes to VCC of the 74ALVCHS162830 have been added on the inputs to clamp overshoot. The bus hold feature retains the inputs' last state whenever the input bus goes to high impedance. This prevents floating inputs and eliminates the need for pull up or pull down resistors.

The outputs of the 74ALVCHS162830 which are designed to sink up to 12 mA, include equivalent 26 W series resistors to reduce overshoot and undershoot.

To ensure the high-impedance state during power up or power down, the output-enable (OE) input 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.

The 74ALVCHS162830 is characterized for operation from 40 to +85 °C.
