INTRODUCTION
The monolithic UT63M147 Transceivers are complete
transmitter and receiver pairs for MIL-STD-1553A and 1553B
applications. Encoder and decoder interfaces are idle low.
The receiver section of the UT63M147 series accepts biphase-
modulated Manchester II bipolar data from a MIL-STD-1553
data bus and produces TTL-level signal data at its RXOUT and
RXOUT outputs. An external RXEN input enables or disables
the receiver outputs.
