1. 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 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 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.
