74ACT1284
IEEE 1284 Transceiver
General Description
The 74ACT1284 contains four non-inverting bidirectional
buffers and three non-inverting buffers with open Drain out-
puts and high drive capability on the B Ports. It is 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 B Ports to
switch from open Drain to a high drive totem pole output,
capable of sourcing 14 mA on all seven buffers. The DIR
input determines the direction of data flow on the bidirec-
tional buffers. DIR (active HIGH) enables data flow from A
Ports to B Ports. DIR (active LOW) enables data flow from
B Ports to A Ports.
