Question:
Page 14 of the datasheet (Rev 0; 3/15) says pin 15 (Y\) is only used when differential mode is enabled. However, page 28 shows Y\ connected to ground in TTL mode. Which is correct?
Something similar is shown on page 27 for A\, B\ and Z\ for singe-ended HTL mode. What is the correct connection for these pins when not used in differential mode?
Answer:
The MAX14890E inverting inputs, A\, B\, Z\ and Y\ are high impedance when not in differential mode. The various datasheet figures show these either as unconnected or connected to ground. Either connection scheme is fine.
