HD74ALVCH16827
20-bit Buffers / Drivers with 3-state Outputs
ADE-205-140B (Z)
3rd. Edition
December 1999
Description
The HD74ALVCH16827 is composed of two 10-bit sections with separated output enable signals. For
either 10-bit buffer section, the two output enable (1
OE1
and 1
OE2
or 2
OE1
and 2
OE2
) inputs must both
be low for the corresponding Y outputs to be active. If either output enable input is high, the outputs of that
10-bit buffer section are in the high impedance state. Active bus hold circuitry is provided to hold unused
or floating data inputs at a valid logic level.
