The device is put into shutdown mode by driving
RE
high and DE low. If these inputs are in this state for less than 50 ns, the device is guaranteed not to enter
shutdown mode. If the enable inputs are in this state for at least 3000 ns, the device is guaranteed to have entered shutdown mode.

Stresses above those listed under Absolute Maximum Ratings
may cause permanent damage to the device. This is a stress
rating only; functional operation of the device at these or any
other conditions above those indicated in the operational
section of this specification is not implied. Exposure to absolute
maximum rating conditions for extended periods may affect
device reliability.
ESD CAUTION
ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily accumulate on
the human body and test equipment and can discharge without detection. Although this product features
proprietary ESD protection circuitry, permanent damage may occur on devices subjected to high energy
electrostatic discharges. Therefore, proper ESD precautions are recommended to avoid performance
degradation or loss of functionality.

Table 4. Pin Function Descriptions
Pin No. Mnemonic Description
1 RO
Receiver Output. When enabled, if A > B by 200 mV, then RO = high.
If A < B by 200 mV, then RO = low.
2
RE Receiver Output Enable. A low level enables the receiver output, RO.
A high level places it in a high impedance state.
3 DE
Driver Output Enable. A high level enables the driver differential inputs A and B.
A low level places it in a high impedance state.
4 DI
Driver Input. When the driver is enabled, a logic low on DI forces A low and B high,
while a logic high on DI forces A high and B low.
5 GND Ground.
6 A Noninverting Receiver Input A/Driver Output A.
7 B Inverting Receiver Input B/Driver Output B.
