描述 Description

The 74AVCH16244 is a 16-bit non-inverting buffer/line driver with 3-state outputs. The device can be used as four 4-bit buffers, two 8-bit buffers or one 16-bit buffer. The3‑state outputs are controlled by the output enable inputs nOE. A HIGH on nOE causes the outputs to assume a high impedance OFF-state.
The 74AVCH16244 is designed to have an extremely fast propagation delay and a minimum amount of power consumption.
To ensure the high-impedance output state during power-up or power-down, nOE should be tied to VCC through a pull-up resistor (Live Insertion).
A dynamic controlled output (DCO) circuitry is implemented to support termination line drive during transient.
The 74AVCH16244 has active bus-hold circuitry to hold unused or floating data inputs at a valid logic level. This feature eliminates the need for external pull-up or pull-down resistors.
