DESCRIPTION
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 valid signal, RO will be high.
Receiver Enable. A low enables the receiver. A high input forces the receiver
output into a high impedance state.
Driver Enable. A high on DE enables the driver. A low input will force the driver
outputs into a high impedance. If RE is high with DE low, the part will enter a
low power shutdown state.
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.
Ground. *The Exposed Pad on the DFN packages should be connected to
ground.
Noninverting Driver Output for the LTC2857-1, LTC2857-2, LTC2858-1 and
LTC2858-2. High impedance when the driver is disabled (LTC2858-1) or
unpowered.
Inverting Driver Output for the LTC2857-1, LTC2857-2, LTC2858-1 and
LTC2858-2. High impedance when the driver is disabled (LTC2858-1) or
unpowered.
Inverting Receiver Input (and Inverting Driver Output for the LTC2856-1 and
LTC2856-2). Impedance is > 96kΩ in receive mode or unpowered.
Noninverting Receiver Input (and Noninverting Driver Output for the LTC2856-1
and LTC2856-2). Impedance is > 96kΩ in receive mode or unpowered.
Positive Supply. 4.5V < VCC < 5.5V. Bypass with a 0.1µF ceramic capacitor.
