PIN ASSIGNMENTS
Pin Name
Pin Function
RO
Receiver Output. When RE is low and if (A – B) ≥ -40mV, RO is High. If (A – B) ≤ - 200mV, RO
is low.
2
RE
Receiver Output Enable. RO is enabled when RE is low. When RE is high, RO is high imped-
ance. Drive RE high and DE low to enter shutdown mode. RE is a hot-swap input.
3
DE
Driver Output Enable. When DE is high, outputs are enabled. When DE is low, outputs are
high impedance. Drive DE low and RE high to enter shutdown mode. DE is a hot-swap input.
4
DI
Driver Input. With DE high, a low level on DI forces non-inverting output low and inverting out-
put high. Similarly, a high level 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
8
Vcc
Positive Supply Vcc. Bypass Vcc to GND with a 0.uF capacitor.
