General description

The 74AVCH16245 is a 16-bit transceiver featuring non-inverting 3-state bus compatible

outputs in both send and receive directions. The device features two output enable inputs

(nOE) for easy cascading and two send/receive inputs (nDIR) for direction control.

Inputs nOE control the outputs so that the buses are effectively isolated. This device can

be used as two 8-bit transceivers or one 16-bit transceiver.

The 74AVCH16245 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, tie pins nOE

A Dynamic Controlled Output (DCO) circuitry is implemented to support termination line

drive during transient (see Figure 4 and Figure 5)

The 74AVCH16245 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.
