†

Whenever the flag output is deasserted (logic low), the DATA and CLOCK outputs are silenced. See the Flag Output section on

page 2 for the DATA and CLOCK output signal levels.

‡

Power supply noise in excess of 50 mVp-p may degrade the performance of the receiver. See User Interface section for recom-

mended power supply filtering.
