1.
General description
The 74LVCH322244A is a 32-bit non-inverting buffer/line driver with 3-state outputs. The
3-state outputs are controlled by the output enable inputs nOE. A HIGH on input nOE
causes the outputs to assume a high-impedance OFF-state.
The device is designed with 30
series termination resistors in both HIGH and LOW
output stages to reduce line noise.
To ensure the high-impedance state during power-up or power-down, input nOE should
be tied to VCC through a pull-up 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. In 3-state operation, outputs can
handle 5 V. These features allow the use of these devices in a mixed 3.3 V and 5 V
environment.
Bus hold on data inputs eliminates the need for external pull-up resistors to hold unused
or floating data inputs at a valid logic level.
