Seven-segment decoders, polarity and digit drivers, voltage reference, and clock circuit are integrated on-chip. These devices incorporate a display hold (HLDR) function. The displayed reading remains indefinitely, as long as HLDR is held high. Conversions continue, but output data display latches are not updated. The reference – ) is not available as it is with the TC7106/ low input (VREF – 7107.
