handbook, halfpage
Wide supply voltage range from 1.2 to 3.6 V
Complies with JEDEC standard no. 8-1A/5/7
CMOS low power consumption
Input/output tolerant up to 3.6 V
Dynamic Controlled Output (DCO) circuit dynamically
changes output impedance, resulting in noise reduction
without speed degradation
Low inductance multiple power and ground pins for
minimum noise and ground bounce
Power off disables outputs, permitting live insertion.

DESCRIPTION
The 74AVC16245 is a 16-bit transceiver featuring
non-inverting 3-state bus compatible outputs in both send
and receive directions.
The 74AVC16245 features two output enable inputs (nOE)
for easy cascading and two send/receive inputs (nDIR) for
direction control. Input nOE controls the outputs so that the
buses are effectively isolated. This device can be used as
two 8-bit transceivers or one 16-bit transceiver.
This product 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, input nOE should be tied to V
through a pull-up resistor (live insertion).
A DCO circuitry is implemented to support termination line
drive during transient (see Figs 1 and 2).
