RO (Pin 1): Receiver Output. If the receiver output is enabled
(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 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 out-
put 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.
Y (Pins NA/8/12): Positive Driver Output for LTC2855.
Z (Pins NA/9/13): Negative Driver Output for LTC2855.
B (Pins 9/10/14): Negative Receiver Input (and Negative
Driver Output for LTC2854).
A (Pins 8/11/15): Positive Receiver Input (and Positive
Driver Output for LTC2854).
VCC (Pins 10/12/16): Positive Supply. VCC = 3.0V < VCC <
3.6V. Bypass with 0.1μF ceramic capacitor.
