Description

The 74LVC161284 contains eight high speed non inverting bidirectional buffers and eleven control/ status non-inverting buffers with open drain outputs fabricated in silicon gate C2MOS 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 of the 74LVC161284 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.
