DESCRIPTION
The 74ALVCH16827 is a 20-bit non-inverting buffer/driver with
3-State outputs for bus oriented applications.
The 74ALVCH16827 consists of two 10-bit sections with separate
output enable signals. For either 10-bit buffer section, the two output
enable (1OE1 and 1OE2 or 2OE1 and 2OE2) inputs must both be
active. If either output enable input is high, the outputs of that 10-bit
buffer section are in high impedance state.
The 74ALVCH16827 has active bus hold circuitry which is provided
to hold unused or floating data inputs at a valid logic level. This
feature eliminates the need for external pull-up or pull-down
resistors.
