SN74LVC162244 General Description
This 16-bit buffer/driver is designed for 2.7-V to 3.6-V VCC operation.
The SN74LVC162244 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.
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.
The SN74LVC162244 is characterized for operation from 40°C to 85°C.
