description

This 16-bit buffer/driver is designed for 2.7-V to

3.6-V VCC operation.
The SN74L VC162244 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 . It provides true outputs and symmetrical active-low output-enable
(OE) inputs. The outputs, which are designed to sink up to 12 mA, include 26-Ω resistors to reduce overshoot
and undershoot.

Active bus-hold circuitry is provided to hold unused or floating data inputs at a valid logic level.
T o 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.
The SN74LVC162244 is characterized for operation from –40°C to 85°C.

†

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.

NOTES: 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.
