DESCRIPTION
The 74LVCZ161284A contains eight high speed
non inverting bidirectional buffers and eleven
control/status non-inverting buffers with open
drain outputs fabricated in silicon gate C
2
MOS
technology. It’s intended to provide a standard
signaling method for a bi-direction parallel
peripheral in an Extended Capabilities Port Mode
(ECP). The HD (Active HIGH) input pin enables
the Cable port to switch from Open Drain to a high
drive totem pole output, capable of sourcing 14mA
on all thirteen buffer and 84mA on PERI LOGIC
OUTPUT buffer. The DIR input determines the
direction of data flow on the bidirectional buffers.
DIR (Active HIGH) enables data flow from A port
to B port. DIR (Active LOW) enables data flow
from B port to A port. The Y output (Y9-Y13) stay
in the high state after power-on until an associated
input A9-A13) goes high. When an associated
input goes high, all Y outputs are active, and non
