HD74ALVCH162244

Notes: 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.
1. The input and output negative voltage ratings may be exceeded if the input and output clamp current ratings are observed. 2. This value is limited to 4.6 V maximum.
3. The maximum package power dissipation is calculated using a junction temperature of 150°C and a board trace length of 750 mils.

The HD74ALVCH162244 is designed specifically to improve both the performance and density of 3-state memory address drivers, clock drivers, and bus oriented receivers and transmitters. The device can be used as four 4-bit buffers, two 8-bit buffers, or one 16-bit buffer. HD74ALVCH162244 provides true outputs and symmetrical active-low output-enable (OE) inputs.

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 HD74ALVCH162244 resistor is determined by the current sinking capability of the driver.Active bus hold circuitry is provided to hold unused or floating data inputs at a valid logic level.All outputs, which are designed to sink up to 12 mA, include 26 W resistors to reduce overshoot and undershoot.
