DESCRIPTION

The 74LVC161284 contains eight high speed non

inverting bidirectional buffers and eleven control/

status non-inverting buffers with open drain

outputs

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. It is available in the

commercial temperature range.
