Important notice
Dear Customer,
On 7 February 2017 the former NXP Standard Product business became a new company with the
tradename
Nexperia.
Nexperia is an industry leading supplier of Discrete, Logic and PowerMOS
semiconductors with its focus on the automotive, industrial, computing, consumer and wearable
application markets
In data sheets and application notes which still contain NXP or Philips Semiconductors references, use
the references to Nexperia, as shown below.
Instead of http://www.nxp.com, http://www.philips.com/ or http://www.semiconductors.philips.com/,
use

DESCRIPTION
The 74ALVCH162244 is a high-performance, low-power,
low-voltage, Si-gate CMOS device, superior to most advanced
CMOS compatible TTL families.
The 74ALVCH162244 is a 16-bit non-inverting buffer/line driver with
3-State outputs. The device can be used as four 4-bit buffers, two
8-bit buffers or one 16-bit buffer. The 3-State outputs are controlled
by the output enable inputs 1OE and 2OE. A HIGH on nOE causes
the outputs to assume a high impedance OFF-state. The
74ALVCH162244 is designed with 30Ω series resistors in both HIGH
and LOW output states.
The 74ALVCH162244 has active bus hold circuitry which is provided
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.
