Proportional signal levels. A logic device encodes signals with levels proportional to its power supply voltage (V
Question:
Proportional signal levels. A logic device encodes signals with levels proportional to its power supply voltage (VDD) according to Table 1.4.
Suppose two such logic devices A and B send signals to one another and the supply of device A is VDDA = 1.0 V. Assuming that there are no other noise sources and that the two devices have a common ground (i.e., 0 V is the same level in both devices), what is the range of supply voltages for device B, VDDB, over which the system will operate properly?
