DESCRIPTION

The 74LVC(H)162244A is a high-performance, low-power,
low-voltage, Si-gate CMOS device, superior to most advanced
CMOS compatible TTL families. Inputs can be driven from either

3.3V or 5V devices. In 3-State operation, outputs can handle 5V .
These features allow the use of these devices in a mixed 3.3V/5V
environment.

The 74LVC(H)162244A is a 16-bit non-inverting buf fer/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
nOE

causes the outputs to assume a high impedance OFF-state.
The 74LVC(H)162244A is designed with 30Ω series termination
resistors in both HIGH and LOW output stages to reduce line noise.
The device can be used as four 4-bit buffers, two 8-bit buffers or one
16-bit buffer.

The 74LVCH162244A bus hold data inputs eliminates the need for
external pull up resistors to hold unused inputs.
