No Connect.
Receiver Output. High when A > B by 200 mV or Low when A < B by 200 mV.
Receiver Output Enable. With
RE
low, the receiver output RO is enabled. With
RE
high,
the output goes high impedance. If
RE
is high and DE low, the ADM3491 enters a
shutdown state.
Driver Output Enable. A high level enables the driver differential outputs, Y and Z. A low
level places it in a high impedance state.
Driver Input. When the driver is enabled, a logic Low on DI forces Y low and Z high while
a logic high on DI forces Y high and Z low.
Ground Connection, 0 V.
Noninverting Driver Output Y.
Inverting Driver Output Z.
