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 3.3 or 5 V devices. In 3-state operation,
outputs can handle 5 Volt. These features allow the use of
these devices as a mixed 3.3 and 5 V environment.
The 74LVC(H)16244A 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
device features four Output Enables (1OE, 2OE, 3OE and
4OE), each controlling four of the 3-state outputs. A HIGH
on nOE causes the outputs to assume a high-impedance
OFF-state.
The 74LVC(H)16244A is identical to the 74LVC16240A
but has non-inverting outputs.
The 74LVCH16244A bushold data inputs eliminates the
need for external pull-up resistors to hold unused inputs.
