NAME

FUNCTION

1

RO

Receiver Output. If A > B by -50mV, RO will be high; if A < B by 200mV, RO will be low.

2

/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.

3

DE

Driver Output Enable. The driver outputs are enabled by bringing DE high. They are high impedance

when DE is low. If /RE is high and DE is low, the device will enter a low-power shutdown mode. 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 B high and output A low. Similarly, a high on DI forces output

B low and output A high.
