DESCRIPTION

The 74LVC(H)16244A 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)16244A 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
the outputs to assume a high impedance OFF-state. The device can
be used as four 4-bit buffers, two 8-bit buffers or one 16-bit buffer.

The 74LVC(H)16244A is identical to the 74LVC16240A but has
non-inverting outputs.

The 74LVCH16244A bus hold data inputs eliminates the need for
external pull up resistors to hold unused inputs.
