DESCRIPTION:
The LVC16827A provides high-performance bus interface buffering for
wide data/address paths or buses carrying parity. Two pairs of NAND-ed
output enable controls offer maximum control flexibility and are organized
to operate the device as two 10-bit buffers or one 20-bit buffer. Flow-through
organization of signal pins simplifies layout. All inputs are designed with
hysteresis for improved noise margin.
