4 / 8 page LTC490 4 CC HARA TERISTICS A TYPICALPERFOR CE PI FU C S TI VCC (Pin 1): Positive Supply; 4.75V ≤ VCC ≤ 5.25V. R (Pin 2): Receiver Output. If A > B by 200mV, R will be high. If A < B by 200mV, then R will be low. D (Pin 3): Driver Input. A low on D forces the driver outputs A low and B high. A high on D will force A high and B low. GND (Pin 4): Ground Connection. Y (Pin 5): Driver Output. Z (Pin 6): Driver Output. B (Pin 7): Receiver Input. A (Pin 8): Receiver Input.
