INTRODUCTION
The monolithic UT63M1XX Transceivers are complete
transmitter and receiver pairs conforming fully to MIL-STD-
1553A and 1553B. Encoder and decoder interfaces are idle low.
UTMC’s advanced bipolar technology allows the positive
analog power to range from +5V to +12V or +5V to +15V,
providing more flexibility in system power supply design.
The receiver section of the UT63M1XX 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.
