In one embodiment, a decision feedback equalizer helps mitigate intersymbol interference in a bi-directional signaling environment. In the particular embodiment, the decision feedback equalizer includes a voltage-to-current converter to source a received differential current to first and second node, a latch to provide logic signal when comparing currents sourced to the first and second nodes, a memory unit to store the logic signals, and a mapping circuit to source first and second feedback currents to the first and second nodes. This embodiment further includes a transmitter to transmit data over a transmission line during receiving, and a digital-to-analog converter to provide a differential current to the first and second nodes to substantially cancel that part of the received differential currents contributed by the transmitter. In this embodiment, the mapping circuit may comprise a lookup table to map the stored logic signals into code words, and another digital-to-analog converter to source differential current to the first and second nodes in response to the code words. Other embodiments are described and claimed.
