DESCRIPTION
The 74ACT1284 contains four high-speed non-in-
verting bidirectional buffers and three non-invert-
ing buffers with open drain outputs fabricated in
silicon gate C
It’s intended to provide a standard signaling meth-
od for a bidirection parallel peripheral in an Ex-
tended Capabilities Port mode (ECP).
The HD (active High) input pin enables the B ports
to switch from Open Drain to a high drive totem
pole output, capable of sourcing 14mA on all sev-
en buffers. 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.
ESD protection is greater than 2000V per Method
3015.7 of MIL-STD-883B. It’s available in the
commercial temperature ranges.
