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.
The 3-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 (see Figs 1 and 2).
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.
