DescriptionThis 16-bit buffer/driver is designed for 1.65-V to 3.6-V VCC operation.The SN74LVCZ16240A 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 SN74LVCZ16240A can be used as four 4-bit buffers, two 8-bit buffers, or one 16-bit buffer. This device provides inverting 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 VCC through a pullup resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver. Inputs can be driven from either 3.3-V or 5-V devices. This feature allows the use of these devices as translators in a mixed 3.3-V/5-V system environment.Active bus-hold circuitry is provided to hold unused or floating data inputs at a valid logic level.
The SN74LVCZ16240A is characterized for operation from 40°C to 85°C.
