Description

This 16-bit buffer/driver is designed for 1.65-V to 3.6-V VCCoperation. The SN74ALVCH162244 is designed specifically to improve 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 equivalent 26-resistors to reduce overshoot and undershoot. To ensure the high-impedance state during power up or power down, OE\ should be tied to VCCthrough a pullup resistor; the minimum value of the 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. The SN74ALVCH162244 is characterized for operation from –40°C to 85°C.
