noise and ground bounce
Supports Live Insertion
All inputs have bus-hold.
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, pins nOE should be tied to V
CC
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 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.
