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 3.3 or 5 V devices. In 3-state operation,
outputs can handle 5 V. These features allow the use of
these devices as a mixed 3.3 and 5 V environment.
The74LVC(H)162244Aisa16-bitnon-invertingbuffer/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, 2OE, 3OE and 4OE. A HIGH on nOE causes the
outputs to assume a high-impedance OFF-state.
The 74LVCH162244A bushold data inputs eliminates the
need for external termination resistors to hold unused
inputs.
The 74LVC(H)162244A is designed with 30
series
termination resistors in both HIGH and LOW output stages
to reduce line noise.
