Description
1
RO
Receiver Output. When
RE
is low and A - B
When
RE
is low and A - B
(more positive than) 200mV, RO will be high.
(more negative than) –200mV, RO will be low.
2
RE
Receiver Output Enable. Take
RE
low to enable RO; RO is high impedance when
RE
is high.
Take
RE
high and DE low to enter low-power shutdown mode.
3
DE
Driver Output Enable. Take DE high to enable driver outputs. These outputs are high
impedance when DE is low. Take RE high and DE low to enter low-power shutdown mode.
4
DI
Driver Input. With DE high, a low on DI forces non-inverting output low and inverting output
high. Similarly, a high on DI forces non-inverting output high and inverting output low.
5
GND
Ground
6
A
Non-Inverting Receiver Input and Non-Inverting Driver Output
7
B
Inverting Receiver Input and Inverting Driver Output
