Product data sheet
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 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 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.
2. Features and benefits
 Wide supply voltage range from 1.2 V to 3.6 V
 Complies with JEDEC standards:
 JESD8-7 (1.2 V to 1.95 V)
