NOTES:
Stresses greater than those listed may cause permanent damage to the device. This is a stress
rating only, and functional operation of the device at these or any other conditions outside those
indicated in the operational sections of this specification is not implied. Exposure to absolute
maximum rating conditions for extended periods may affect reliability.

V
CC and VCCQ must be within 300mV of each other at all times; this is not required when power
is ramping down.
REF ≤ 0.6 x VCCQ; however, VREF may be ≥ VCCQ provided that VREF ≤ 300mV.

CC and VCCQ must track each other. VCC and VCCQ are tied on this device.
REF is expected to equal VCCQ/2 of the transmitting device and to track variations in the DC level of the same. Peak-to-peak noise on VREF may not exceed ±1 percent of the DC value. Peak-to-peak AC noise
on VREF may not exceed ±2 percent of VREF. This measurement is to be taken at the nearest VREF bypass capacitor.
VTT is not applied directly to the device. VTT is a system supply for signal termination resistors, is expected to be set equal to VREF and must track variations in the DC level of VREF
