Pin description
Symbol
Name and function
RO Receiver output. If A>B by 200mV, RO will be high; if A<B by 200mV, RO will be low
RE
Receiver output enable. RO is enabled when RE is low; RO is high impedance when RE
is high. If RE is high and DE is low, the device will enter a low power shutdown mode.
Driver output enable. The driver outputs are enabled by bringing DE high. They are high
DE
impedance when DE is low. If RE is high DE is low, the device will enter a low-power
shutdown mode. If the driver outputs are enabled, the part functions as line driver, while
they are high impedance, it functions as line receivers if RE is low.
DI
GND
Driver input. A low on DI forces output A low and output B high. Similarly, a high on DI
forces output A high and output B low
Ground
A
Non-inverting receiver input and non-inverting driver output
B
Inverting receiver input and inverting driver output
VCC
Supply voltage: VCC= 3V to 3.6V
3/22
