FUNCTION TABLES

PIN FUNCTIONS

RO: 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.

RE: Receiver Enable. A low enables the receiver. A high

inputforcesthereceiveroutputintoahighimpedancestate.

DE: 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.

DI: 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.

GND: Ground.

Y: Noninverting Driver Output for LTC2851 and LTC2852.

High impedance when driver disabled or unpowered.

Z:InvertingDriverOutputforLTC2851andLTC2852.High

impedance when driver disabled or unpowered.

A: Noninverting Receiver Input (and Noninverting Driver

Output for LTC2850). Impedance is >96kΩ in receive

mode or unpowered.

B: Inverting Receiver Input (and Inverting Driver Output

for LTC2850). Impedance is >96kΩ in receive mode or

unpowered.

VCC: Positive Supply. 3V ≤ VCC ≤ 3.6V. Bypass with 0.1µF

ceramic capacitor.

Exposed Pad: Ground. The exposed pads on the DFN

packages must be soldered to ground.

NC: Not connected internally for LTC2852 in SO-14

package.
