description/ordering information
This 16-bit buffer/driver is designed for 2.7-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 can be used as four 4-bit buffers, two
8-bit buffers, or one 16-bit buffer. This device
provides inverting outputs.
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.
During power up or power down when VCC is between 0 and 1.5 V, the device is in the high-impedance state.
However, to ensure the high-impedance state above 1.5 V, 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.
