FUNCTIONAL DESCRIPTION  
RECEIVER  
The HI-1565 family of data bus transceivers contain differ-  
ential voltage source drivers and differential receivers.  
They are intended for applications using a MIL-STD-1553  
A/B data bus. The device produces a trapezoidal output  
waveform during transmission.  
The receiver accepts bi-phase differential data from the  
MIL-STD-1553 bus through the same direct or transformer  
coupled interface as the transmitter. The receiver’s differ-  
ential input stage drives a filter and threshold comparator  
that produces CMOS/TTL data at the RXA/B and RXA/B  
output pins.  
TRANSMITTER  
Data input to the device’s transmitter section is from the  
complementary CMOS /TTL inputs TXA/B and TXA/B.  
The transmitter accepts Manchester II bi-phase data and  
converts it to differential voltages on BUSA/B and BUSA/B.  
The transceiver outputs are either direct or transformer  
coupled to the MIL-STD-1553 data bus. Both coupling  
methods produce a nominal voltage on the bus of 7.5 volts  
peak to peak.  
Each set of receiver outputs can be independently forced  
to a logic "0" (HI-1565) or logic “1” (HI-1566) by setting  
RXENAor RXENB low.  
MIL-STD-1553 BUS INTERFACE  
A direct coupled interface (see Figure 2) uses a 1:2.5 ratio  
isolation transformer and two 55 ohm isolation resistors  
between the transformer and the bus.  
The transmitter is automatically inhibited and placed in the  
high impedance state when both TXA/B and TXA/B are ei-  
ther at a logic “1” or logic “0” simultaneously. A logic “1” ap-  
plied to the TXINHA/B input will force the transmitter to the  
high impedance state, regardless of the state of TXA/B and  
TXA/B.  
In a transformer coupled interface (see Figure 3), the  
transceiver is connected to a 1:1.79 isolation transformer  
which in turn is connected to a 1:1.4 coupling transformer.  
The transformer coupled method also requires two  
coupling resistors equal to 75% of the bus characteristic  
impedence (Zo) between the coupling transformer and the  
bus.
