DESCRIPTION
PIN CONFIGURATIONS
To minimize the package size for this function, the
transmitter outputs are internally connected to the receiver
inputs, so that only two pins are required for connection to
each coupling transformer.

The receiver section of each channel converts the 1553
bus bi-phase data to complementary CMOS / TTL data
suitable for inputting to a Manchester decoder. Each
receiver has a separate enable input which can be used to
force the output of the receiver to a logic 0 (HI-1565) or
logic 1 (HI-1566).

FUNCTIONAL DESCRIPTION
The HI-1565 family of data bus transceivers contain differential 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.
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.
The transmitter is automatically inhibited and placed in the
high impedance state when both TXA/B and TXA/B are either at a logic “1” or logic “0” simultaneously. A logic “1” applied to the TXINHA/B input will force the transmitter to the
high impedance state, regardless of the state of TXA/B and
TXA/B.
RECEIVER
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 differential input stage drives a filter and threshold comparator
that produces CMOS/TTL data at the RXA/B and RXA/B
output pins.
Each set of receiver outputs can be independently forced
to a logic "0" (HI-1565) or logic “1” (HI-1566) by setting
RXENA or 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.
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.

HEAT SINK - ESOIC & CHIP-SCALE PACKAGE
Both the HI-1565PSI/T/M and HI-1566PSI/T/M use a
20-pin thermally enhanced SOIC package. The
HI-1565PCI/T and HI-1566PCI/T use a plastic chip-scale
package. These packages include a metal heat sink
located on the bottom surface of the device. This heat
sink should be soldered down to the printed circuit board
for optimum thermal dissipation. The heat sink is
electrically isolated and may be soldered to any
convenient power or ground plane..
