8 / 18 page LTC2859/LTC2861 8 285961fc RO(Pin1):ReceiverOutput.Ifthereceiveroutputisenabled (RE low) and A > B by 200mV, then RO will be high. If A < B by 200mV, then RO will be low. If the receiver inputs are open, shorted, or terminated without a valid signal, RO will be high. RE (Pin 2): Receiver Enable. A low enables the receiver. A high input forces the receiver output into a high imped- ance state. DE (Pin 3): Driver Enable. A high on DE enables the driver. A low input will force the driver outputs into a high imped- ance. If RE is high with DE and TE LOW, the part will enter a low power shutdown state. DI (Pin 4): Driver Input. If the driver outputs are enabled (DE HIGH), then a low on DI forces the driver positive output LOW and negative output HIGH. A high on DI, with the driver outputs enabled, forces the driver positive output HIGH and negative output LOW. (DD/DE/GN) TE (Pin 5): Internal Termination Resistance Enable. A high input will connect a termination resistor (120Ω typical) between pins A and B. GND (Pins 6,11/6,13/6): Ground. Pins 11 and 13 are backside thermal pad, connected to Ground. SLO (Pins 7/7/11): Driver Slew Rate Control. A low input will force the driver into a reduced slew rate mode. Y (Pins -/8/12): Positive Driver Output for LTC2861. Z (Pins -/9/13): Negative Driver Output for LTC2861. B (Pins 9/10/14): Negative Receiver Input (and Negative Driver Output for LTC2859). A (Pins 8/11/15): Positive Receiver Input (and Positive Driver Output for LTC2859). VCC (Pins 10/12/16): Positive Supply. 4.5V < VCC < 5.5V. Bypass with 0.1µF ceramic capacitor. pin FuncTions |
