PIN NAME
DESCRIPTION
1
RO
Receiver output: if A>B by 200mV, RO will be high; if A<B by 200mV, RO will be low.
2
RE
Receiver output enable. RO is enable when RE is low; RO is high impedance when
RE
is high.
3
DE
Driver output enable. The driver outputs, Y and Z, are enabled by bringing DE high. They
are high impedance when DE is low. If the driver outputs are enabled, the parts function
as line drivers. While they are high impedance, they function as line receivers if RE is
low.
4
DI
Driver Input. A low on DI forces output Y low and output Z high. Similarly, a high on DI
forces output Y high and output Z 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; 4.75V≤VCC≤5.25V
